6.8.4 Battery service
WARNING!
Danger of cauterisation ! Danger of explosion!
When working on the battery do not use open fire, do
not smoke!
The battery contains acid. Do not let acid come in con-
tact with skin or clothes!
Wear protective clothing!
Do not lay any tools on the battery!
For recharging remove the plugs from the battery to
avoid the accumulation of highly explosive gases.
ENVIRONMENT!
Dispose of the old battery environmentally.
Maintenance free batteries also need care. Mainte-
nance free only means that the fluid level does not
need to be checked. Each battery suffers under self-
discharge, which may, in not checked occasionally,
even cause damage to the battery as a result of
exhaustive discharge.
The following therefore applies for the service life:
Switch off all consumers (e.g. ignition, light, inside light,
radio).
Check open-circuit voltage of the battery at regular intervals.
At least once per month.
Reference values: 12.6 V = fully charged; 12.3 V = 50% dis-
charged.
Recharge the battery immediately after an open-circuit
voltage of 12.25 V or less is reached. Do not perform quick
charging.
The open-circuit voltage of the battery occurs approx. 10 hours
after the last charging process or one hour after the last discharge.
After each charging process allow the battery to rest for one
hour before taking it into service.
For resting periods of more than one month you should
always disconnect the battery. Do not forget to perform reg-
ular open-circuit voltage measurements.
