Battery care

cause creepage current. This can cause the
batteries to discharge.

fuel. Cleaning agents containing fuel corrode
the battery housing.

If dirt enters the battery cell, self-discharg-
ing of the battery is increased and the battery
may be damaged.

terminal clamps with acid-resistant grease.

cially available cleaning agents.
