How to properly charge a dry-charged battery

Without exception, all car batteries run on electrolyte. It is thanks to this substance that batteries have the ability to accumulate electricity when charging, and then provide it to the car’s electronics for operation. Along with alkaline electrolyte, the most used is acidic. Today we will talk in more detail about this substance, its essence and principles of operation.

This set of actions has had a positive result, significantly reducing the damage caused by this phenomenon, which we do not see or feel, but which is a reality. Currently, in addition to selling equipment and tools for use in technical assistance, we also offer some static energy control tools, such as wristbands, gloves, anti-static blankets.

More detailed information can be found. Do not dispose of this product as unsorted municipal solid waste. Rechargeable batteries have a limited number of charge cycles. You can charge and discharge the battery more than 300 times before its capacity is significantly reduced.

A few words about acid electrolyte

Acid electrolyte is one of the components of many rechargeable batteries (AB). This substance is a mixture of two main elements:

acid, which is often sulfuric acid;
and distilled water.

A similar solution is often used to refill lead-acid batteries, which have been actively used in the automotive industry for about 170 years. Note that in this case the electrolyte is in a liquid state and requires constant topping up. Noticeably less often when using cars, gel batteries are used, which are based on the same solution with the composition noted above, but there it is no longer in a liquid state, but in a more or less thickened state.
The number of charge cycles also varies depending on use and operating conditions. You can charge the battery through a wall outlet. When syncing is complete, the battery icon will begin to fill the screen. . Do not leave the battery completely discharged for too long or constantly charge it, otherwise it may affect its service life.

Low battery notifications
Until recently, electric cars seemed like a mirage, a gimmicky invention with no market in the oil-dependent world. Today, however, there is a period of enormous expansion, mainly due to greater environmental awareness among consumers. Eco-friendly, low cost and small, ideal for those living in the city as an alternative to other green means of transport such as bicycles. But what are its features?

In the usual version, the liquid electrolyte requires periodic filling, because during operation it partially evaporates and goes through the gas outlet sections of the battery. Also, depending on the season, the solution should be either less or more dense. It is by correctly maintaining the amount and density of the acid electrolyte from the battery used that the highest efficiency can be achieved. In fact, only these two indicators of a mixture of acid and distilled water require proper monitoring and appropriate adjustment.

There are two types of electric vehicles: those that are purely electric and those that are hybrid, which have an internal combustion engine that is capable of moving the vehicle and charging the batteries. The operation of one or the other engine varies depending on the situation: at low speeds only electric operates, at higher speeds it also acts as combustion.

Hybrid cars have what's called a "regenerative brake," which instead of dissipating energy as heat stores it to recharge the batteries. Thus, it recovers 15% of the energy produced. While hybrid cars have pollutant emissions, even if they fall, electric cars have the advantage of not producing any pollutants - no exhaust, particulate matter, or water vapor. The only problem in this case depends on the country's energy production: if it comes from thermoelectric power plants, the electric car will still have minimal environmental impact, but if it comes from renewable sources, the engine will be 100% green. Also in the pipeline are prototypes of electric cars with an attached photovoltaic plant that will be able to power themselves, but there is still time.

Life time

It is important to understand that an acid electrolyte is precisely a solution that does not have an expiration date. The latter for a mixture of this kind is determined based on how well it is able to perform the functions assigned to it. The main indicators affecting the current use of the battery include:

Electric motors have a remarkable energy efficiency level of 90%, much more than a conventional gasoline engine. Finally, they are very silent, and in large cities this can reduce noise levels, which is important. Another advantage for big cities is that when you stop, so when you get into traffic, electric cars don't consume power. During the stop phase, the electric motor does not operate.

The performance of modern electric vehicles is no longer relegated to the first model introduced to the market. They have gone from being slow and heavy cars to fast and quick cars that have nothing to envy their fuel-efficient counterparts. They have excellent performance during acceleration and have high top speeds. The body is more aerodynamic, as there is no need for air intakes to cool the engine.

electrolyte density;
temperature regime of its operation;
battery charge level.

Monitoring of these indicators must be carried out in accordance with special technical literature and some GOST standards. It’s probably not worth going into details of the normal parameters, because not a single motorist will fully comply with them. It’s better to pay attention to the basic rules necessary to comply with the correct operating mode of acid batteries. To be more precise, their list includes:

In terms of autonomy, they have improved significantly compared to a few years ago: the latest models can travel up to 150 km before recharging, and the batteries have a longer lifespan. Considering the average 30km home journey is an electric car, this is a good choice, but for those who have to move a hybrid car around, a hybrid car is probably a better choice. The only significant cost is replacement every 5-6 years of battery life. Their biggest disadvantage is the market price.

Some countries, including Italy, offer more or less an incentive to buy an electric car. The higher price level is due to the battery, especially due to its poor diffusion. But we believe that the introduction of technology will lead to a fall in prices. Another painful key is the inability to use them for long trips: only the most advanced models can reach 150 km of autonomy, so circling in the city is the only way to use it. It will be necessary to wait for the future, even close enough, for greater autonomy.

Maintaining normal electrolyte density. A normal indicator of this parameter is considered to be anywhere from 1.07-1.3 grams per milliliter (approximate sulfuric acid content is 30-40%). It is officially recommended to adhere to an electrolyte density of 1.21-1.24 g/ml in warm seasons, and 1.27-1.30 in cold seasons. This battery parameter is checked using special instruments - analyzers or hydrometers. A decrease or increase in density occurs by adding distilled water or correction electrolyte;
Battery charge monitoring. Note that when the battery is discharged, the density of the electrolyte drops, so it is advisable that the battery is always charged to 60-100%. It is better to avoid complete battery discharge or, if it occurs, completely change the electrolytic solution and restore the battery in the mode recommended by the manufacturer;
The battery is always fully charged. This, again, is necessary to maintain good electrolyte density;
Maintaining a normal electrolyte level in the separator. Here it is worth considering the indicators recommended by the manufacturer. That is, fill in the electrolyte according to existing standards;
Avoiding overloading the battery by operating too vigorously or operating in high temperature conditions at frequent intervals. These phenomena, which is not surprising in principle, negatively affect the condition of any electrolyte, including an acid solution.

By adhering to only the 5 rules noted above for the operation of acid batteries and corresponding electrolytes, it is quite possible to extend their service life by 2 or even 3 times. Remember this.
They also suffer from very low temperatures, which can reduce winter productivity by up to 26%. You should have a car available to get more miles when you need to go. When purchasing a new car, consider this information and be conscious of what your vehicle stands for, knowing that green solutions exist and are effective and efficient.
In nature, “hybrid” means the combination of two different species. The same goes for hybrid cars, which have two engines: one electric and one gasoline. They work together to provide a range of benefits that improve quality of life and the environment.

The procedure for filling and topping up acid electrolyte in the battery

From the information presented above, it is clear that it is important to maintain the acid electrolyte of any battery at the proper level and condition. The use of low-quality or small quantities of solution is a factor that can significantly reduce the service life of the battery.

Double the power, double the fun

These engines work together to release more power and reactivity, depending on demand.

Brain power, no matter the journey

The electric motor is activated at start-up with stored energy in the batteries and provides the boost needed to reach low speeds. After a certain speed and time when you need more power, switch to a gasoline engine.

You'll appreciate the fuel savings

When it is stopped: both motors are automatically switched off so that they do not lose energy. Overtaking: The two engines work in pairs to provide the vehicle with the necessary acceleration. It's no secret that city driving involves increased fuel consumption for most vehicles. Hybrids are different from other vehicles.

During operation of acid batteries, it may be necessary to either completely change the electrolyte or top it up. Any of these processes should be carried out when the following signs appear:

the battery has stopped holding a charge or is doing so extremely poorly;
electrodes, separators and their plates are intact;
The battery was charging, but there was no result or it was, but extremely weak.

Do you observe these moments specifically in your situation? Then changing or partially topping up the acid electrolyte is simply necessary, because perhaps it is they that will revive the battery.

Feeling calm

When you select a power mode, you will notice something special: silence! The silence and calmness of the engine is truly an experience you have to try to believe. Electric mode also provides zero emissions and a smooth driving experience.

Benefits of using a hybrid car

Consider a plug-in hybrid, such as an electric car or a hybrid car. There is a long list of things that our hybrid vehicles can guarantee you the best in: whether you're driven by a love of driving, a desire to cut costs or just want to have fun while respecting the environment.

If motorists do not have any particular difficulties with changing the solution, many cannot cope with refilling it. In fact, there is nothing complicated in carrying out this procedure and the procedure for its implementation is as follows:

Remove the battery from the car;
Take the battery to the place where it is topped up, which must be protected from third parties, current, fire and water;
Prepare a protective suit and some tools to top up the electrolyte;
After this, carefully remove the separator covers and use an analyzer to check the density of the electrolyte, as well as its filling level. If the density is higher than normal, dilute the electrolyte with distilled water; if it is lower, add correction electrolyte. It is advisable to add the solution to the level recommended by the battery manufacturer, but a slight deviation from it while maintaining the normal density of the electrolyte, checked by the analyzer, is also acceptable;
Then all that remains is to assemble the battery to its original form and return it to the car structure.

Note! When adding distilled water, we recommend purchasing the liquid not from pharmacies, but from car dealerships. The former often sell ordinary tap water, which is not recommended to be poured into the battery.
With a hybrid car, everything is simpler: just get in and drive
Our hybrid vehicles have been designed to be easy to drive. When the power button is pressed, there is no noise, but only a message appears to alert you that the car is ready to go! Plus, since the hybrid system is self-monitoring and all hybrid cars are automatic, simply place the shift lever in Manual and then enjoy the drive in complete serenity.
Hybrid: two engines working in tandem
With a hybrid car, you can enjoy wet environments thanks to the electric motor. This powertrain is ideally matched to the strong powerful petrol engines and when you need them, the two engines will work in sync in tandem to create the ultimate driving experience.

Note that when replacing or adding a large amount of electrolyte, it is advisable to additionally recharge the battery. When completely replacing the solution, the battery must be fully charged; when partially topping up, a third or a quarter of the duration of a full charge is required.

Our hybrid car batteries are always charged

You don't have to worry about how long you're traveling, with our hybrid cars you only need to fill up the fuel to continue your journey, just like any regular car.
When the battery is low on charge, it starts the motor, which charges it with energy. And that's not all, every time you brake, the energy is recycled to charge the battery - so nothing is wasted. Our hybrid vehicles' batteries are always charged: good for your wallet and the environment. Not only will you enjoy being on the wheel of a hybrid car, but you will also appreciate how much it will save you. Our hybrid cars have been designed for city driving by switching their engines off as often as possible to save fuel and money.

Electrolyte preparation process

Summarizing today's material, it would not be amiss to consider the process of preparing an acid electrolyte with your own hands. Of course, buying a solution is not so difficult, especially considering its low cost, but many motorists still like to “do some chemicals.” For these purposes, when preparing an acid electrolyte, it is important:

All hybrid benefits in Italian regions and cities

Since then, our hybrid family has grown and today we offer our customers up to six hybrid models to choose from: a model for all your needs. In many Italian regions and municipalities, owners of a hybrid car can enjoy the following amenities. The brand is also calculated based on the power of a single heat engine, rather than the total power of the vehicle. Trust us, there is nothing difficult about owning a hybrid car. In fact, we are confident that these eight simple hybrid truths will put an end to your worries once and for all.

First, prepare sulfuric acid with a density of about 1.83 g/ml and distilled water - 1.4 g/ml. At least, this is what GOST recommends for the preparation of an acid electrolyte, from which it is undesirable to deviate;
Secondly, find a cast iron or plastic container with a tight-fitting lid, similar items for stirring the electrolyte and an analyzer (hydrometer);
And thirdly, organize a place for preparing the solution, which must be protected from third parties, current, fire and water.

The car charges itself, there is no need to connect it to the network; The battery in our hybrid vehicles is just as important as the engine. That's why we studied batteries that can last the entire life cycle of a car. Today, our batteries power our lives, every day, all over the world, from. To find out first-hand about the potential of the Hybrid, you can do a special test.

General questions about the hybrid

The only driver intervention is when he decides to go into electric-only mode, but only for short journeys. Departure: When starting or at low speed, the vehicle is powered by the electric motor. This saves fuel and reduces exhaust emissions. . For driving pleasure, because hybrids are fun cars to drive.

After basic preparation, you can proceed directly to preparing the acid electrolyte. The order of operation looks like this:

Place 1-2 liters of distilled water in the prepared container;
Then sulfuric acid is slowly added and mixed thoroughly;
After this, the analyzer checks the density of the electrolyte and, if necessary, corrects it either by adding distilled water (to reduce the density) or by adding acid (to increase the density).

The prepared mixture should be stored in a glass container with a tightly closed rubber stopper. The storage location of the acid electrolyte should be protected from the sun and children.

Perhaps the most important information on the issue under consideration today has come to an end. We hope the material presented above was useful to you. Good luck with car repairs and on the roads!

As you know, nothing lasts forever, and one of the main elements of the car - the battery - someday the time comes to retire. When choosing a new power source, car owners can see a dry-charged battery. What it is? Which side should you approach it from and how to use it? How to charge a dry-charged battery? We will answer these and other questions in our article.

Dry-charged battery: what is it, why are they produced and how much do they cost?

This type of battery got its name due to the absence of electrolyte in the banks at the time of completion. The production of dry-charged batteries assumes that the lead plates are charged and the product itself is hermetically sealed in a factory environment. The price of such a power source is from 1500 rubles.

What to put in a dry battery? Since a dry-charged battery is a regular lead-acid battery, it must be filled with electrolyte. The latter can either be purchased ready-made in a store or prepared independently from acid and distilled water.

Dry-charged batteries are produced so that the owner has the opportunity to store the battery for a long time before its first use, for example, during storage. Due to the low rate of chemical processes, batteries without electrolyte are practically not subject to self-discharge. This allows you to store it for an incredibly long time.

Possible options

Once you have brought the amount of electrolytic solution to a constant level, check the voltage value with a voltmeter. There are several options available:

If the sensor shows 12.5 volts or more, then the battery is ready for use.
If the indicator reports a voltage between 10.5 and 12.5 V, the device must be recharged.
When the voltage at the terminals is below 10.5 V, the battery is considered damaged.

The first case indicates that the dry-charged battery is ready for use. Commissioning was successful and all that remains is to place the battery in the vehicle. The second option tells us that in order to use the battery it is necessary to recharge it, and the last option tells us that the storage or manufacturing conditions were violated and the device is not suitable for operation.

Shelf life and shelf life of a dry-charged battery

The popularity of this type of power source is due to the fact that there is no electrolyte in the banks, which means there is no chemical reaction. The lead plates are hermetically sealed and are not affected by moisture or air. Therefore, the shelf life of a dry-charged car power source in factory condition can reach 40 years. Despite the long shelf life, the shelf life of a dry-charged battery is approximately 7 years. The fact is that the chemical process in dry batteries, although significantly slowed down, still occurs. Therefore, after long-term storage (30-40 years), it is possible that the plates will be inoperative.

The battery should be stored in an upright position without direct sunlight. You should also make sure that the battery caps are closed.

Dry charged battery

Batteries that are familiar to us arrive on the shelves in a charged state: the electrolytic solution (sulfuric acid) has already been poured into a plastic container with lead plates inside.

Dry-charged batteries come to the market empty. They have a plastic shell with a lead reagent placed inside, but they do not contain an acid solution. This solution gives the electricity source some advantages, the main one being the possibility of long-term storage.

Dry-charged battery: commissioning

Dry-charged batteries cannot be installed on a vehicle immediately after purchase. This factor often forces car owners to choose conventional batteries. However, starting to use a dry-charged battery is not as problematic as it seems. Before performing work, it is necessary to prepare all the tools: electrolyte, hydrometer, voltmeter and charger.

What to put in a dry battery

Before installing a dry-charged battery, you must fill it with electrolyte with a density of 1.27-1.28 g/cm3. You can purchase a ready-made solution or mix it yourself.

Attention! If you decide to dilute the electrolyte yourself, then use personal protective equipment - gloves, a mask. Sulfuric acid, which must be diluted with water, is a strong chemical. Protection is needed to avoid the harmful effects of vapors and to prevent burns from acid.

How to refill a dry-charged battery

Depressurize the battery. Depending on the design, you need to remove special gaskets under the plugs, side plugs on the battery cover or bosses on the plugs. Please note: on some power supplies, it is recommended to cut through the caps first to allow the vapors to escape.
Fill the dry-charged battery with electrolyte to the required level. If there are marks, follow them. If they are missing, determine the level yourself - the solution should cover the plates by 2 centimeters.
Leave the car battery for a while (2-3 hours). It is necessary for a chemical reaction to begin between the lead plates and the electrolyte. Attention! The acid solution level may decrease slightly. In this case, it needs to be topped up.
Measure the density of the electrolyte using a hydrometer. Indicators should not be lower than 1.27 g/cm3. A lower acid concentration requires recharging the battery to the specified value.
Check the voltage with a voltmeter. The battery will be fully charged at 12.7 volts.

Table 1. Indications of electrolyte density and battery voltage depending on the degree of its charge.

Below are the approximate volumes of electrolyte for different batteries of different capacities.

Table 2. The amount of electrolyte in the battery depending on the A/h capacity.

Rules for using dry-charged batteries

The service life of dry-charged energy sources that are ready for operation can be significantly extended by following basic operating rules. Firstly, you will need to check the voltage at the terminals once a month in the “idle” state and under load.

At the same time, measure the density of the electrolyte - it should not fall below the regulated level. If necessary, recharge the battery according to the instructions.

Secondly, once every six months, give the battery a workout - discharge it to the minimum value, and then completely replenish its supply of electricity. Finally, to ensure that dry-charged batteries last as long as possible, use a charger with a stabilized voltage - it fills the battery in a gentle manner.

Is it possible to charge a dry battery?

Quite often the question comes up: is it possible to charge a dry-charged battery? If the source is put into operation, then its charging is no different from this process for maintenance-free batteries. It may be necessary to restore the capacity of a dry-charged battery when it has already been in use for some time. The battery charging process is described in detail in the next section.

If we are talking about a new battery, then you should remember: a feature of using a dry-charged battery is that it should not be charged without electrolyte.

How to properly charge a dry-charged battery

Whether the battery needs to be charged or not depends on the storage life of the battery. If the battery was manufactured quite recently and has been in storage for no more than one year, most likely, a long recharging will not be required; three to four hours will be enough, and it is possible that the charger will not be needed at all. An “older” battery will have to be charged from 5 to 10 hours, and when the battery is fully charged, the electrolyte begins to boil. All that remains is to check the density; if it is normal, the battery can be installed in the car and used.

The battery must be charged from a stationary charger with a current equal to 0.1 battery capacity, for example, if the battery is 60 A/h, then the charging current is no more than 6 Amps. An important condition: the density of the electrolyte should not change for at least three hours, therefore, after recharging, measurements with a hydrometer should be carried out twice - immediately and after the specified time has elapsed. The voltage is also checked, it should also remain constant. It is necessary to charge the battery before starting operation in two cases:

if the battery was stored after manufacture for more than one year;
if the battery is used under increased load, for example, in frosty winter, with frequent starts, in a car with a large engine capacity.

Dry-charged batteries are bought by car owners who are not too lazy to service the car themselves; some drivers also take such a battery as a reserve when the “original” battery is already running low. Of course, the SAKB belongs to the category of serviceable batteries; maintenance-free ones are always filled with electrolyte, which does not change until the very end of the battery’s service life.

Correctly charge the battery as follows:

we check that the battery is not cold; if it was stored outside at a low temperature, it must first be warmed up;
we connect the charger (charger) to the battery, it is very important to install the terminals correctly: connect plus to plus, and minus to minus. As a rule, the positive charger wire is red;
we set the required charging current on the “charger”; it should not exceed 10% of the battery capacity;
We charge for 3-5 hours; if this time is not enough, we leave the battery to recharge for another four hours.

How to properly charge a dry-charged battery

The first replenishment of the dry battery capacity is necessary at the commissioning stage. Instructions for charging this power supply:

Connect the charger in accordance with the polarity;
connect the equipment to the network;
the charge current should be equal to 10% of the battery capacity;
charge the battery for about 5 hours;
If during this time the voltage does not reach 12.5 volts, reduce the current and continue charging.

If the battery is fully charged, the electrolyte will begin to boil, and the voltage level and density indicators will remain unchanged for some time.

How to charge a dry-charged battery

For a battery to be considered charged, the voltmeter must read 12.5 volts or more. The state at which it can be recharged is 10.5 V. Otherwise, restoring it will be difficult, if not impossible. With a new dry-charged battery there will be no such problem. The main thing is to fill it with electrolyte with the specified density.

Instructions for charging the battery:

It is necessary to connect the “+” and “-” terminals to the charger, observing the polarity.
Turn on the charging station.
The charging current must be set to a level of 10% of the battery capacity.
Charge for 5 hours.
If the battery does not produce the required voltage, you must reduce the charge by 50% and wait another 4 hours.

A fully charged battery will boil, which can be observed with the naked eye. The electrolyte density and terminal voltage will be constant.

Advantages and disadvantages of dry-charged batteries

The dry-charged battery is in demand among motorcyclists and owners of special vehicles. Most often they are purchased in the summer. Therefore, the main advantage is a long shelf life, which is important primarily for the manufacturer, because the battery will be operational several years after it comes off the production line. But this property of dry batteries is also attractive for vehicle owners - they can be purchased in reserve.

A dry-charged battery does not require special attention (refilling electrolyte, recharging) - you installed an uncharged battery and forgot about it.

We also note the lower cost of these batteries - from 2 thousand rubles. The price of an acid solution is from 300 rubles.

This type of battery is also convenient for transportation - you don’t have to worry about electrolyte spilling.

The disadvantages of dry batteries include the difficulty of commissioning, the inability to immediately put it in a car after purchase, and a certain amount of time spent getting it into working condition.

Advantages of dry-charged batteries

Despite the complexity of putting a dry-charged battery into operation, it is quite popular due to its advantages. The first of these is a long shelf life. Conventional lead-acid batteries are stored for no more than 4 years and require special conditions. “Dry” installations retain their properties for 7 years and do not require additional storage conditions.

The second advantage is ease of transportation. When not in use, it lacks electrolyte, which may begin to leak for some reason. In addition, this installation is lightweight.

The third advantage is the cost of a dry-charged battery. Putting it into operation with your own hands will cost around 300 rubles, and the average price of the battery itself starts to rise from 1900 rubles, which is significantly lower than ready-made batteries.

How to choose a dry-charged battery: evaluation criteria

See all offers on the battery market.
Consider the characteristics of the vehicle (volume and type of internal combustion engine, availability and power of additional equipment).
Study the technical recommendations for the battery for your car.
Decide on the capacity of the power source.
Consider the cost of the battery - this will affect the choice of class.
Select its characteristics and determine the originality of the product (manufacturer, tightness, integrity).

We hope that after reading this article, dry-charged batteries are no longer “dark horses” for you. You also learned how to properly charge dry batteries, so all you have to do is try it. Share your experience in purchasing and operating this type of power source for a car. How did you recharge a dry-charged battery? We will also be happy to answer all your questions.
