— Maintainable. Only classic lead-acid batteries (see "Type") can be serviced: they are easy to distinguish even externally — by the presence of removable plugs that provide access to internal containers with electrolyte. The latter is a mixture of sulfuric acid with water, and with each charge, some of this water "boils away" (decomposes into oxygen and hydrogen and evaporates). This happens especially intensively during overcharging or charging at high voltage. Battery maintenance consists of periodically replenishing the water reserves in the electrolyte — without this, a decrease in its level leads to damage to the plates due to contact with air, which irreparably worsens the battery's characteristics. On average, maintenance should be carried out 1-2 times a year (15-20 thousand km of mileage for a passenger car) and these periods usually coincide with the terms of scheduled maintenance. However, this value may vary depending on the characteristics of both the battery itself and its operation; More detailed information is usually contained in the instructions for specific models. "Refilling" should be done exclusively with distilled water, since even a relatively small amount of foreign impurities can damage the plates.

— Maintenance free. As the name suggests, such batteries do not require the maintenance described above; this is achieved in a number of ways, in particular by filling the elect...rolyte with a reserve for the entire service life or using gel (see "Type"). With obvious advantages due to ease of use, maintenance-free batteries at the same time have one drawback: they are much more sensitive to deep discharge (capacity decreases), and, accordingly, tolerate cold and long periods of downtime worse.

The form factor describes the general design features of the battery, primarily the way the terminals are installed and their dimensions, as well as the dimensions of the battery itself.

— European. A distinctive feature of European batteries are the terminals, somewhat recessed into the case. Due to this, this form factor is considered safer than the Asian form factor — the risk of a short circuit is lower when the battery falls on a conductive surface or when a metal object hits it. In addition, the terminals themselves are usually made in the form of Euro cones (see below for more details). As for the dimensions, European batteries have more depth and less height than Asian ones. As the name implies, this form factor is found in cars of European manufacturers, mainly passenger cars.

— Asian. Asian batteries are easy to identify by the terminals protruding from the top of the case; also, these terminals can be noticeably thinner than European ones, because. many models use JAP cones (although not all). If compared in size, then the "Asians" are taller and thinner than the "Europeans" (more precisely, they have less depth). This option is popular with Japanese and Korean automakers, and is also quite widespread among trucks.

— American. A rather rare form factor on our roads — due to the fact that cars from American manufacturers are most often delivered to us in the form...of modifications adapted to Europe or Asia; original versions are rare. Lightweight batteries of this form factor have "USA" screw terminals (see "Terminals"), located not on the cover, but on the front wall of the case. At the same time, both “purely American” and combined batteries are produced, which, in addition to a pair of USA terminals on the front wall, also have contacts on the cover that are more familiar to east european drivers. And in cargo batteries of this form factor, the terminals are usually installed on the cover, in the left side location.

When choosing a battery, it makes sense to clarify which form factor is optimal for your car: a discrepancy in this parameter can cause compatibility problems up to the complete impossibility of installing a battery.

In this case, polarity refers to the location of the terminals on the battery. Traditionally, it is named according to the location of the "+" terminal when looking at the battery from the front (or, in the case of side terminals, from the side closest to which they are located).

— + left. In relation to passenger cars, such polarity in the CIS countries is often called "direct" or "ours". At the same time, in trucks (see "Purpose") the situation is the opposite - the left "plus" is the European standard.

— + right. In passenger cars, the right "plus" is typical mainly for European models, for which this polarity in the CIS countries received the unofficial name "euro" or "reverse" (as opposed to the domestic "direct"). In batteries for trucks, everything is the other way around.

— + right/ + left. This marking means that this battery model is available with both right and left “plus” (see above), and you can choose the option depending on the car model.

Note that the above division into “direct” and “reverse” polarity is not absolute, and in any case, before purchasing a battery in your car, this parameter should be clarified separately.

The starting power of the battery, measured according to the EN standard (the unified standard of the European Union). According to this standard, the starting power is the maximum power that the battery can deliver for 30 seconds at an electrolyte temperature of -18 °C without the voltage dropping below a certain level (for standard 12 V batteries - not lower than 7.2 V). The term "starting" appeared because this operating mode is similar to starting an engine, when the battery has to deliver a high-power power to the starter for a short time.

The recommended starting power value is generally related to the weight category of the vehicle: the heavier it is, the more powerful the power usually needed to start it. And many manufacturers directly indicate the recommended values in the characteristics of a particular vehicle model. If the battery is purchased as a replacement, the general rule is: its starting power should be no less than that of its predecessor.

Note that in practice, starting power designations may be encountered according to 3 more standards: SAE (USA), DIN (Germany) and TU (GOST 959-91). The first is almost identical to EN, and DIN and TU are quite easy to translate into EN and vice versa: they are similar to each other, and each of them gives a number approximately 1.7 times smaller than NE. That is, for example, to replace a 200 A battery according to TU, you should look for a model with a power of at least 340 A (200 * 1.7) according to EN.
