Removal corrosion from terminals and poles

Terminal (photo on the left) and the battery pole (photo on the right) should be thoroughly cleaned until shiny.
Battery maintenance consists of the following operations:
- periodic checking and restoration of electrolyte levels;
- checking the condition of the battery case by inspection;
- battery cleaning, corrosion removal (white deposits) on the battery mounting parts and terminals (see fig. Removing corrosion from terminals and poles) with an aqueous solution of soda ash;
- checking the reliability of the terminal fastening on the poles;
- checking the battery charge with a voltmeter or hydrometer.
A fully charged battery should have a voltage of 12.6 V. Maintenance-free batteries have a built-in color indicator. A blue spot in the indicator window indicates that the battery is fully charged; when the indicator becomes discolored, the battery should be charged.
It is recommended to charge the battery with a current of 2A for 12-16 hours.
