Do not remove battery terminal covers unnecessarily.
2. Do not lay tools on the battery. These can lead to short circuiting, overheating and battery
bursting.
3. Take particular care when the battery has been in service for a long time or has just been
charged as highly explosive gas is emitted.
Ensure adequate ventilation.
10.3.7.2 Battery checking and care
Even so-called 'maintenance-free' batteries need a degree of care to obtain their maximum opera‐
tional life.
The outside of the battery and the terminals should be cleaned regularly with a soft cloth. This
avoids current leaks and minimizes the discharge rate.
