It's unpleasant when the car battery runs out when you need to travel. This may be due to the operation of the internal equipment when the engine is not running, with contact closure, excessive voltage and some other factors.
Necessary
- - automatic charger;
- - a source of electric current.
Instructions
Step 1
First of all, disconnect the electrical cables from the attachment point and remove the battery from the car. Before connecting the battery to the charger, remember that it should only operate with DC current.
Step 2
After disconnecting the battery, open the filler caps (if any) and connect the correct polarities of the battery and the charger ("mass" with "mass", and "force" with "force").
Step 3
Next, connect the device to the network. If charging does not occur, check that the terminals are connected correctly and properly. The capacity of the battery determines how long it takes to charge it. Also at this stage, pay considerable attention to tension. Despite the same method of charging absolutely all batteries, please note that it is strictly forbidden to use a high charging current. The maximum allowed voltage should not be more than 1/10 of the battery capacity. If you are dealing with a deeply discharged battery, charge with a small current of 1.5 to 2.0 A.
Step 4
During the charging process, take time to periodically check the temperature and density of the electrolyte, as well as the voltage of the battery. When the temperature reaches 45 ° C, immediately reduce the amperage by half, and in some cases you may interrupt the charging process. You can consider the storage battery fully charged when gas is emitted from all the cells of the battery, and within two or more hours the density and voltage of the electrolyte do not change. If urgently needed, change the density of the electrolyte by adding distilled water if the battery is to be serviced. The density should not be more than 0.01 g / cm3.
