The car stands with the hood open, and its dejected owner rushes around it, having discovered that his iron "horse" is immobilized. Moreover, the car itself is in good working order and fueled, but there is no way to start it due to a discharged battery.
How so? Just yesterday the battery was cranking the starter properly, and there were no signs of malfunction. Yes, it happens. Low temperature can lead to battery discharge. And sometimes, if it is not of the first "freshness," there is no other way out than buying a new battery.
Batteries available for sale are divided into several types (indicated on the sticker on top or side of the battery): calcium (maintenance-free), low-antimony (low-maintenance), and hybrid batteries.
Calcium batteries have several positive characteristics. They hold high current well, practically do not self-discharge, and do not boil over. They require no maintenance. Disadvantages include the fact that they require high-quality operation of the vehicle's electrical equipment without sharp voltage fluctuations.
Low-antimony batteries, compared to calcium ones, are less demanding on the quality of electrical equipment operation, more tolerant to voltage fluctuations, and resistant to deep discharges. Disadvantages include low current and the need for maintenance
Hybrid batteries combine the advantages of calcium and low-antimony ones. They have decent current characteristics, while evaporation of distilled water is practically absent. Endurance is also at a proper level. Such batteries include A-mega, Bosch S5, Varta Silver Dynamic, etc.
Choosing a battery
Most owners, when choosing a new battery, tend to opt for maintenance-free batteries. But do not forget that they are also more expensive - by almost 50%. They are made using the so-called calcium technology.

When choosing any type of battery, it is necessary to pay attention to the capacity and the value of the starting current. These are the two most important parameters. They must be no less than those specified by the vehicle manufacturer. It should be noted that a significant excess of these parameters is also undesirable. This is due to the fact that the vehicle's electrical equipment is designed for a certain value. An exception may be vehicles with a modified electrical system.
When selecting, you also need to consider the dimensions of the new battery. The fact is that the battery placement in the car has a specific niche. A larger battery simply will not fit there, and a smaller one will be difficult to secure.
Pay attention to the placement of the terminals. On the same battery model, terminals may have different sizes and be positioned differently. This is due to the fact that they can be used in vehicles from different manufacturers with different types of battery connections.
Additional protective elements in the design are welcome. These can be special plastic shields covering the terminals and reducing the risk of short circuits, or a built-in charge indicator. An ergonomic carrying handle will also not be superfluous. Yes, indeed, the need to carry the battery is not frequent, but when it is necessary, the handle will not be superfluous.
When purchasing, keep in mind that some new models of certain brands may use specific technologies that extend the service life or other battery parameters. Thus, specialists of the Autoportal.ua online store recommend choosing batteries with AGM technology (lead-acid) for vehicles with a start-stop system. The electrolyte in them is absorbed (not liquid), so such batteries are capable.
