In the practice of car owners, sometimes paradoxical situations arise when a battery that has worked for a relatively short period of time, for some unknown reason, can hardly cope with the responsibilities assigned to it related to starting the engine.
It is necessary
21 watt bulb
Instructions
Step 1
In addition to all the problems, the electrical equipment is found to be in good condition and functioning normally. The charging relay disconnects and connects the battery to the on-board network in time. The generator works flawlessly. But the battery stubbornly does not want to get infected.
Step 2
At car service stations, when a similar situation arises from the masters, you can get one single piece of advice: replace the old battery with a new one, and not suffer.
Step 3
But such a statement is rather controversial. Before hurting your budget, you need to try to get the battery to take charge.
Step 4
One of the ways to restore the functionality of the battery, oddly enough it sounds, is to completely discharge the battery. After reading the text, you should not immediately grab the crowbar and short-circuit the battery at the terminals.
Step 5
The battery is discharged under conditions that are as close as possible to the operating conditions. In other words, a 21-watt car light is connected to the battery, and under this load, the battery is discharged until the voltmeter shows the voltage at its terminals at 10.5 volts. When the specified level of battery discharge from the battery is reached, turn off the light bulb. And then connect it to the charger.
Step 6
As a rule, after performing one, maximum - two full discharge / charge cycles of the battery, its properties are restored, and it can still serve for quite a long time, at least a year.
