Rechargeable battery (battery) is one of the most important elements of the car. Despite the fact that she is not directly involved in the movement, without it you cannot start the engine and activate the electronic system of the car. The importance of the battery the owner is especially urgent in the cold season. When the mark thermometer drops below zero, defective or worn out battery quickly losing charge. In recent years, the market of automotive parts became popular calcium batteries. Today we'll learn what they are, and answer common question drivers: “How to charge a calcium battery?”
Calcium battery (Ca/Ca) – kind of the battery lead plate which is alloyed with calcium. The amount of calcium in the battery, compared to the total mass of the plate very slightly (not more than 0.1 %). Thus, a battery of this type would more correctly be called lead-calcium, but in everyday life somehow stuck another formulation, the shorter and more promising. As alloying element, calcium, in these batteries was replaced by antimony. It has been used for these purposes for many years, but had a number of shortcomings, which prompted scientists to search for new, more suitable substances.
There is another, less common type of calcium batteries – silver-calcium batteries (Ca/Ag). It is easy to guess that they, by analogy with the previous example, commonly referred to simply as silver. Plates of such batteries are made of lead-calcium alloy, which adds quite a bit of silver. The presence of this element means that the battery of the shortcomings of models such as Sa/Sa, while retaining all their advantages. The only problem with these battery – the high price which is due not only to the cost of raw materials, but also the manufacturing complexity of the battery.
To understand the fundamental differences of this type of battery, briefly acquainted with the methods of their production, which is also called “calcium technology”. In lead-antimony battery grid made by casting. When this method was used for lead-calcium alloy, calcium is simply burnt out. Therefore, the grid for the CA/CA batteries have decided to make using the stamping. It allows you to produce plate more complex shape while maintaining the outer frame.

Today calcium batteries can not displace from the market traditional antimony, and the main reason for this is the difficulty of manufacturing arrays. Therefore, manufacturers maintenance-free batteries do both and something in between – a hybrid.
Let us Examine the pros and cons of a calcium battery.
The Advantages of such batteries are the following:
These batteries will be the best solution for car with a fully working electrical equipment. Many novice drivers, parked your car, forget to turn off her radio, headlights, cabin lights and other electricity consuming device. As a result, next day it turns out that the battery is low. In the cold season, this problem is particularly acute. Therefore, if the machine system is provided, independently turn off all electrical consumers after Parking, the novice driver will be easier to protect yourself from such problems as the calcium-discharged battery.
For all its benefits, calcium car battery has some disadvantages:
Speaking of which, a battery of this type can be used only for cars. Wherever there is a possibility of a deep discharge (for example, boats), they are not used. But it's not a minus, and operating the feature.
Now let's look at how to charge a calcium battery.
The First thing worth noting is talking about charging calcium battery – it in any case can not “boil”. The fact that the gases produced during electrolysis can destroy the lubrication of the plates. Another important point – measuring the electrolyte density in calcium battery with a standard hydrometer is useless. The fact that in different parts (“banks") battery, this figure can vary greatly, so to obtain adequate data will not work. However, given the fact that most calcium batteries are maintenance free, most likely, this aspect of measurement will not affect you.
As mentioned above, the battery of this type is highly undesirable to bring up the deep, and even more full charge. And the reason for this lies not only in the long term reduce the battery capacity. The fact that calcium sulfate is not soluble in water and extremely difficult to dissolve in the electrolyte. Therefore, when a deep discharge occurs clogging of the plates, which greatly complicates the movement of charge. And even if you charge the battery at a voltage above 15 V, the electrolyte may not reach the proper density. Thus, to charge-discharge calcium batteries unless absolutely necessary is not worth it.
Charging calcium battery consists of the following steps:
We looked at how to charge a calcium battery from zero. Of course, if this procedure is carried out as a preventive measure, the first two or even three phases can be eliminated. The frequency of recharging depends on several factors: time of year of battery life and usage. In warm time of the year with a new battery and periodic travel long-distance on charge, you can forget for 1-2 months. And Vice versa – in winter, if the battery is old, and a mode of driving - mostly city, charging will become a regular procedure.
To determine the frequency of recharging personally for your car and battery, it is not necessary to wait until the battery runs out. This can happen at the most inopportune moment when you will not be able to return the performance of the car, “lit” it from another machine or putting the battery on charge. How to check the battery? To measure charge it is recommended to use such a simple device, such as a multimeter. It is inexpensive, and in the economyneed everywhere. Carrying out periodic measurements under different weather conditions and operating conditions, you can understand how often your battery needs to recharge, and to protect themselves from a bad situation.
Features calcium batteries, on the one hand, are their competitive advantage, and on the other – require special operation of the device. The following are the key recommendations for the use and maintenance of batteries of this type (some of them already mentioned, but required clarification, and for someone to be new):
Since AKB is one of the most important parts in the design of the car, her choice should be treated with the utmost seriousness. Overly not worth saving, especially if we are talking about calcium batteries. Varta, Bosch, Delkor, Topla – firms which are well established in the market and for products which are recommended to pay attention in the first place.
Today we figured out how to charge a calcium battery and what it represents in principle. Based on the foregoing, we can conclude that this type of battery clearly deserves the attention of drivers, especially beginners. However, it has several disadvantages. Calcium batteries, which we held, can become faithful assistants if they are to competently operate and maintain. Otherwise, the battery always remind myself at the most inopportune moment.
