For motorists, the question almost never loses its relevance: how to charge a car battery? Young motorists especially want to get an answer to it, since the most unexpected situations often arise on the road and in the garage, in which it is simply necessary to have a clear understanding of the technology of charging a car battery.
In order to charge the battery, it is necessary to use a constant current source, a so-called rectifier. The battery and charger terminals must be connected according to the gradation. The most popular among the existing methods of recharging the battery are the procedure that is performed in the presence of direct current, as well as the procedure for which a constant voltage is required. Both methods allow you to charge your car's battery at the right time at the right time.
A charge based on a constant current has certain disadvantages, for example, among them such as the need to control the current for a long time, as well as the presence of very abundant gas formation. However, these disadvantages can be minimized by using the technique of gradually reducing the current (its strength). In the event that the charge and current maintain their readings for 2 hours, it is possible to determine whether the battery is sufficiently charged.
The charge based on constant voltage is the main one for working with car batteries, since it has practically no drawbacks and is quite convenient and simple. The way in which the battery is charged, as well as the way it retains its charge, indicates its condition, which should be carefully monitored, since the battery is the most important automotive element.
