Calcium batteries (Ca/Ca) are a battery whose lead plates are doped with calcium. The Ca content is 0.08-0.09% by weight. A similar look

unlike antimony or hybrid, it is rarely used due to its high cost, although plates with antimony are inferior to plates with calcium. The device is identical to any lead battery car.

Review of calcium batteries (Ca-Ca), which can be bought in stores

It is worth highlighting batteries with the addition of silver - batteries (Ca/Ag). Availability precious metal reduces calcium deficiencies while highlighting its benefits. Silver-plated plates are more expensive than just calcium plates, due to the high cost of the metal and complex technology.

Overview of silver-calcium (Ca-Ag) batteries

The production process for a calcium-containing battery is somewhat different from the standard one. Battery grids are created by stamping because heat When casting, it destroys calcium. For stamping, lead tape is made with the addition of Ca, then it is perforated, creating a complex shape, but maintaining the outer frame.

Advantages

Calcium car batteries are distinguished by the following characteristics:

1. During the production process, increased strength is achieved, creating protection against vibration.
2. About 90% are not serviced. Calcium reduces the electrolysis of water, causing the liquid to evaporate in small quantities.
3. The plates are not afraid of overcharging, since Ca helps withstand up to 15 V.
4. Thin plates allow you to increase their number in the battery, which significantly increases power.
5. The alloy is considered anti-corrosion and protected from external influences.
6. It has a low self-discharge rate, approximately 70% lower than that of antimony analogues.
7. Durable - with proper use, service life is from 5 years.

Flaws

1. Does not tolerate sharp shocks. In a charged battery, the voltage should be maintained above 12 V, preferably 14.5 V. One deep discharge reduces the capacity by 8-20%, and one full discharge - by 50%. Losses are difficult to replace, while 3-4 discharges completely kill these batteries.
2. It is afraid of downtime, as well as frequent switching on and off, so it is recommended for long trips.
3. Expensiveness associated with technology and components. A high-quality mechanism costs from 6 to 15 thousand rubles, although there are models for 2000.

Manufacturers

Among the manufacturers, it is worth highlighting several that create high-quality car batteries:

• TUDOR
• Varta
• Exide

Each manufacturer creates them in a wide price range. They are characterized by high prices, so you should pay attention to mechanisms costing from 5 thousand rubles.

Some automobile factories produce and install their own batteries (Ca/Ca), for example, Ford, Mazda, Nissan, Toyota. It is these four companies that most often use calcium batteries in their cars. average cost- 7 thousand rubles.

To distinguish a fake from the original, you should look at the markings. The housing must indicate the starting current and plate capacity, rated voltage and production date.

Exploitation

Operating schedules for calcium batteries using the example of batteries produced by AKOM

High quality and long work requires proper battery care. When using transport for city driving - frequent stops with the engine turned off, it is recommended to carry out preventive charging, for which it is necessary to purchase a special expensive Charger.

The wrong type of urban driving requires charging every month, while the correct charging is every two.

Charging rules

The calcium battery is charged until it reaches 14.3-14.5 V, the current should be 10% of the maximum declared by the manufacturer, for example, for a 50 amp battery it should be set to 5 A; turns off when the current reaches 0.5 A.

The voltage at the terminals is checked with a voltmeter. 12 V or less indicates the need to charge the battery in order to avoid difficult to recover capacity losses.

Before charging, you need to make sure that the battery is at room temperature. Try to avoid heating above 40-45 degrees Celsius. Boiling is contraindicated - it reduces performance and can lead to failure. Turn off the device if gas emission begins, indicating that the plates are boiling.

A lead-calcium battery does not require a hydrometer. The alloy itself maintains the electrolyte in a non-free state. The liquid is stratified - the liquid one is on top, and the denser one is below.

Full charge during deep discharge

Discharging to 11.5V or below is detrimental to the battery because a reaction occurs in the electrolyte that creates a precipitate of calcium sulfate, blocking the charge from reaching the outlet. It is prohibited to carry out a CTC (control-training cycle), which negatively affects the battery.

Full charging is a long process, since charging calcium battery not easy. The following steps must be completed:

1. Cleaning sulfated plates. A voltage of 15.8 V is supplied, impulsively, for no longer than 8 hours. It helps clean the outer part of sulfates and partially restores the capacity.
2. The charge reception from the device is checked at a current of 1/10 of the starting current, at 12.6 V.
3. At a temperature of 25 degrees the main charge is produced. The current is constant, the voltage is increasing, not exceeding 14.5 V. Duration - until 80% of the capacity is replenished, but no more than 20 hours.
4. Under the same conditions, but now with a constant voltage and decreasing current, the capacitance is brought to 100%. This stage lasts up to 10 hours.
5. After the main stage, you need to check the battery for voltage retention for a couple of minutes.
6. You must enable Recond mode, if available, to restore maximum capacity. If this is not possible, and the rated capacity is less than half of the original, it is recommended to purchase a new battery.
7. In Recond mode it is fed high voltage at low current for 30-240 minutes for controlled gas formation, promoting mixing and separation of the electrolyte.
8. After recovery, a full charge is performed in buffer mode. At 13.6 V and a current of no more than 10 A for 10 days. The cycle restarts when the voltage drops.
9. At the end, preventive charging is carried out at a constantly decreasing current - from 10 to 2% of the base one. The device supports 12.7 - 14.4 V, but if it drops, you must start the cycle from scratch.

Among the chargers it is worth highlighting:

• Automatic Kedr-Auto-10, costing 1,700 rubles.
• Manual Orion PW-265 and ZPU 135. Their prices are 1500 and 4000 respectively. The ZPU is a starter and has a desulfurization function, which affects its cost.

Choose your device carefully as it is not easy to charge a calcium battery correctly. A good one should include desulfurization and recovery regimes. It is desirable that it also be a launcher, that is, capable of short term replenish the battery for the trip and subsequent fully charged.

Technologies are developing very rapidly. Before car owners had time to understand the differences between AGM and GEL, a newcomer appeared on the market - EFB batteries. What are they, what are their features and differences, how much do they cost and many other questions, we hope, will be dispelled after reading this material.

What is EBF? Areas of application, design features and performance characteristics of EFB batteries

Enhanced Flooded Battery translated from English means “improved liquid-filled battery.” Lead plates, unlike traditional batteries, EFBs are almost half as thick, which increases their capacity and charging speed. Each plate is enclosed in a separate envelope made of special microfiber, filled with liquid sulfuric acid electrolyte. This measure helps protect the surface of the plates from sulfation, and in the event of shedding of the active mass, from short circuits and premature exit battery failure. In short, batteries EFB technology have the following nice features:

• resistance to deep discharges, after which EFBs are able to restore capacity to almost 100%, in contrast to conventional batteries, which lose part of their resource;
• can work in wide range temperatures from -50 to +60 °C;
• starting current indicators have been improved by more than a third;
• evaporation of liquid electrolyte is reduced to almost zero;
• doubling the number of charge-discharge cycles without loss of functionality.

Where are EFB batteries used?

Initially, the impetus for creating high-quality new technology During the production of rechargeable batteries, vehicles equipped with a “start-stop” system became widespread in Europe. When the car is stopped in the “Stop” mode, the engine is automatically turned off, and when the clutch is pressed and the brake is released, it quickly starts. At such moments, the load from all electrical appliances falls on the battery, and without increasing charge reception regular battery It just doesn’t have time to fully charge in “Start” mode. An ordinary antimony battery only needs to be discharged to zero several times to make it the main raw material for smelting cargo for fishing. Another situation in which EFB batteries will be needed is use in a car. powerful systems car audio. The main problem is that amplifiers cannot operate efficiently at voltages less than 12 V and at moments of peak load (bass or strong broadband signal) they will emit unpleasant wheezing. EFB battery technology is designed to solve exactly these problems. Thanks to its design features, it perfectly copes with the assigned tasks.

Thus, the main purpose of EFB batteries is frequent use in urban environments, as well as the use of high-quality car audio systems. And one of the industries where they will be indispensable is taxi and other passenger transport, whose drivers love loud music :-).

Review of domestic and foreign EFB battery models

Almost all stores that distribute spare parts for cars offer EFB batteries. Russian production or made in large quantities European companies. The cost of the product will depend on the capacity, power and purpose of the battery.

• TAB Magic. A Slovenian manufacturer whose range of models includes a line of batteries manufactured using EFB technology. At the same time, not only batteries for passenger cars are offered for sale, but also for “trucks”. The cost starts from 3000, but the main difficulty of the purchase is the lack of availability in stores;
• Varta. The company introduces a series called Blue Dynamic Start-Stop, which includes batteries with EFB technology, differing in their capacity and price. The minimum cost of such models starts from 3,500 thousand for a standard 60 Ah;
• Exide. An American company that has been on the market since the 19th century and specializes in the production of high-quality batteries. The EFB line is represented by the Start&Stop series, the cost of which starts from 6,000 rubles. for the lowest capacity sample.

Russian EFB batteries

• AKOM EFB. Products from the same name Russian plant. The manufacturer guarantees excellent characteristics and offers seven types of batteries with capacities from 55 to 100 A/h. The cost of the products, taking into account the stated parameters, is very competitive. For example, the price of an AKOM EFB 60 battery is about 4,000 rubles;

• Ultimatum. A line of batteries from the same manufacturer with improved production technology. Thanks to special additives in the electrolyte, such domestic EFB batteries have improved charge acceptance and service life. The cost of such models starts from 6,000 rubles, depending on the capacity and size;

Since EFB is becoming increasingly popular and in demand every year, we can expect this technology to appear in the product range of both domestic and foreign manufacturers.

Features of charging EFB batteries

Charger EFB battery is not fundamentally different from this process for a traditional AMG battery, since their design is very similar. The main rule that should be observed when implementing it is the use of a high-quality (preferably intelligent) charger and strict adherence to the battery instructions. The EFB battery charger must provide a charging voltage not exceeding 14.4 V. The device must also have a current indication, since during charging of this type It is recommended to monitor its batteries.

Attention! The entire process must take place at an electrolyte temperature no higher than +45 °C; exceeding this threshold leads to increased corrosion processes.

How to properly charge an EFB battery?

In the operating instructions for this type of battery from Varta, only two sentences are devoted to this. The charger should be connected to the appropriate terminals, observing the polarity. The charging process can be considered complete when the charging readings drop below 2.5 A. If the charger is equipped with current and voltage indicators, then the end of the process will be considered when both indicators stop changing.

When charging batteries made using EFB technology, it is not recommended to use the accelerated mode, since the result may be battery failure due to excess gas formation. It is also not allowed to open the plugs, since in this case the chemical equilibrium will be disrupted, leading to a change in the functional qualities of the battery.

Difference between EFB and AGM batteries

The modern motorist has the opportunity to choose from a variety of batteries. In this regard, the question arises, which battery better than EFB or AGM. Each variety has its own advantages and disadvantages, and the owner himself must have the final say. vehicle after weighing all the positive and negative aspects. If we compare EFB and EFB, as they are the closest in design, then the former have the following differences:

• increased thickness of each individual plate, ensuring long service life;
• using less electrolyte and using specially purified lead leads to faster charge accumulation by 45%;
• greater reliability under engine operating conditions under frequent stops;
• are cheaper.

The disadvantages of EFB batteries of this type include:

• less power compared to, which can affect a large number of energy consumers;
• do not support Brake Energy Regeneration technology.

How often you need to resort to this operation depends on the ratio of the power of the car's generator and the power of consumers, as well as on driving conditions. In the summer, almost any car can do without additional battery recharging. The engine starts easily, consumers always turn on the ignition, electric fuel pump (approximately 8-10A), radio (3-4 A), headlights with dimensions (13 A). Even on Idling a working generator produces 40-45A, which is almost enough to power a minimum number of consumers. And at operating speeds, when driving along the highway, for example, the 60-70A supplied by the generator is enough to power consumers and charge the battery.

It's much harder in winter. Negative temperatures reduce the battery capacity, impair the ability to accept a charge, and starting a cold engine requires a large amount of energy. New powerful consumers are turned on on board: heater (5-7 A at first speed and 10-11 A at second), heated windows and mirrors (16-20A), heated seats 5A. The total current consumption is more than 50 A. At idle, the generator can no longer cope with powering consumers; most of the energy is taken from the battery. And even in operating modes, the ability of the generator to recharge the car battery turns out to be very modest; in addition, at negative electrolyte temperatures, the battery does not accept a charge. All this leads to the battery becoming chronically undercharged. The user may not notice this, because even a partial charge is usually enough to start the engine. But chronic undercharging leads to sulfation of the plates, which reduces capacity and increases internal resistance. This in turn shortens the battery life and worsens starting performance. Therefore, in winter you need to systematically recharge the battery.

How often should you recharge your car battery?

The frequency of recharging depends on the car, weather, and travel conditions. For cars with a well-regulated starting system, in mild winter conditions with daily trips over short distances, accompanied by systematic standing in traffic jams, it is enough to charge about once every month or two. Of course, if frosts approach -30°, and each start is accompanied by repeated activation of the starter, then it makes sense to check the battery charge level more often.

And, of course, the battery must be charged immediately if you have discharged it “to zero” unsuccessful attempts starting the engine. Precisely “immediately”, since the density of the electrolyte in a discharged state is low and there is a possibility that it will freeze, damaging the battery. On the other hand, stay lead battery in a discharged state leads to sulfation of the plates.

Electrolyte density, normalized to 25° C, g/cm3	Freezing temperature, °C
1.09	-7
1.12	-10
1.14	-14
1.16	-18
1.18	-22
1.20	-40
1.23	-43
1.24	-50
1.26	-58

There are several battery charging modes: DC, constant voltage, combined.

Basic conditions of a deeply discharged battery

1. The battery was in a discharged state for no more than 2 weeks at room temperature and was not used in the car. It is usually recommended to charge such a battery with a current equal to 0.1 of the rated capacity (6A for a 60Ah battery) until ρ=1.27-1.28 g/cm³ is reached. The charging process may take up to 24 hours. If it is not possible to control the density of the electrolyte using a hydrometer, then you can focus on the state of charge indicator, if available in the battery cover. Green color the indicator indicates the degree of charge ≈ 50% (ρ=1.23 g/cm and above). One of the signs of the end of battery charging is the “boiling” of the electrolyte and the temperature of the battery case reaching ≈ 40 ° C.

2. The battery was in a discharged state for a long time (deep sulfation of the plates occurred).

What is “plate sulfation”.

During charging of a normally discharged battery, small crystals of lead sulfate are easily converted back into metal lead (negative plate) and PbO2 (positive plate), which make up the active mass of the plates. However, if you leave the battery in a discharged state, lead sulfate begins to dissolve in the electrolyte until it is completely saturated, and then falls back onto the surface of the plates, but in the form of large and practically insoluble crystals. They are deposited on the surface of the plates and in the pores of the active mass, forming a continuous layer that isolates the plates from the electrolyte, preventing its penetration deep into the active masses. As a result, large volumes of active mass are “turned off”, and the total battery capacity is significantly reduced.

Restoration of such a battery is usually carried out using the so-called “step mode”:

• start charging with a current of 0.1C20 ≈ 16 hours;
• discharge, for example, with a set of car lamps for 2-3 hours;
• charge with current 0.1C20 until fully charged;

The condition of the battery is checked by measuring the open circuit voltage (OCV). The voltage at the battery terminals is measured 6 - 8 hours after stopping the engine. If the NRC of the battery is below 12.5 V, the battery must be charged. It is advisable to carry out such a check once every 3-4 months.

Charging efficiency primarily depends on the type and quality of the charger. More than half of the chargers on sale are not capable of fully charging a modern battery. Chargers designed to operate in automatic mode, are often set to a voltage of 14.4 - 14.5 V. When this voltage is reached, the green indicator, signaling the end of charging and automatic reduction occurs charging current almost to 0. When purchasing a charger, pay attention to its characteristics. The charger must provide an output charging voltage of 16.2 V. Before you start charging the battery, carefully read the charger instructions - it should describe in detail specifications, all the rules and procedures for performing the work.The battery is considered charged when the electrolyte density in all banks reaches 1.27-1.28 g/cm³, the electrolyte “boils” at the end of charging and the temperature of the battery case reaches ≈ 40 ° C
