Maintenance free battery

Maintenance Free Battery


"Maintenance-free" is a major feature of automotive batteries, but it does not mean that they are really maintenance-free. The maintenance-free label often indicates that the battery does not require water additions, which can be facilitated by choosing grid hardeners (such as calcium).


As a matter of fact, all batteries require some routine maintenance, such as keeping the top of the battery clean, keeping the attached cables tight, and charging or recharging the battery as soon as possible after a significant discharge.
