Caring for batteries consists in periodically cleaning them from dust and dirt. It is also necessary to check the reliability of fastening the battery and the connection of the wire lugs to the battery terminals, the oxidized wire lugs and terminals are cleaned. When cleaning, the minimum layer of metal should be removed, otherwise it is impossible to securely connect the wire tips to the battery terminals. Make sure that the wires are not taut, as this may break the terminals or the battery cover. Lubricate wire lugs and terminals with technical petroleum jelly.
If the car is not used for more than one month, it is recommended to remove the wire from the negative terminal of the battery. During long breaks in operation (winter period) remove the battery from the car and store it in a cool room, but at a positive temperature. It is recommended to recharge the storage battery every three months.
Each discharge, especially a long discharge, shortens the life of the battery.
