Checking the battery

Check the battery for damage such as cracks and a broken case or cover that could lead to electrolyte leakage. Determine the cause of the damage, repair it or replace the battery if necessary. Remove any traces of corrosion with a solution of soda and water.

Check the specific gravity of the electrolyte, while correcting the density depending on the temperature of the electrolyte.

If the density of the electrolyte is less than 1.100 g/cm³, slowly charge the battery with 5A for 14 hours or less, then test the battery under load.

If the electrolyte density is between 1.100-1.220 g/cm³, recharge the battery.

If the electrolyte density is more than 1.220 g/cm³, test the battery under load.

To test the battery under load, discharge the battery with a discharge current of 200 A for 15 seconds, then check the voltage at the battery terminals.

If the voltage is more than 9.6 V, the battery is good and can be used.

If the voltage is between 9.6-6.5V, fast charge the battery, then test it under load.

Attention! If the battery voltage is still less than 9.6 V after recharging, the battery must be replaced.

If the voltage is less than 6.5V, the battery is defective and needs to be replaced.
