The battery works due to the fact that two different metals, being in an acidic solution, create a potential difference, as a result of which an electric current is generated.
Order of execution
1. Cars are equipped with maintenance-free batteries.
2. The battery does not need to be topped up with distilled water.
3. The battery is completely sealed except for small ventilation holes in the lid.
Battery Testing
1. Check the condition of the battery for external damage that could lead to loss of electrolyte. Determine the cause of the damage. Clean the battery with a solution of baking soda and water.
2. Replace battery
3. Check the specific gravity of the electrolyte.
4. Enter the specific gravity correction depending on the temperature of the electrolyte.
5. Over 1,100
Charge the battery slowly.
Charge with a current of no more than 5 A for 14 hours, then test the battery under load.
6. 1,100–1,220
Recharge the battery.
Pay attention to the charging process and precautions.
7. Over 1,220
Check the battery under load.
8. Check the battery under load.
9. Discharge the battery with a discharge current of 200 A for 15 seconds, then check the battery voltage
10. More than 9.6 V
The battery is fine.
11. 9.6-6.5 V
Quickly charge the battery, then test it under load.
Warning! If the battery voltage is still less than 9.6V after repeated charging and discharging, it must be replaced.
12. Less than 6.5V
Replace battery.
