1. Switch off all consuming devices (e.g. ignition, light).
2. Measure the open-circuit voltage of the battery at regular
intervals (at least 1 x per month).
ð
Reference values: 12.6 V = fully charged; 12.3 V = dis-
charged to 50%.
3. Recharge the battery immediately after an open-circuit
voltage of 12.25 V or less is reached. Do not perform boost
charging.
ð
The open-circuit voltage of the battery occurs approx. 10
hours after the last charging process or one hour after
the last discharge.
4. Switch off the charging current before removing the charging
clamps.
5. After each charging process allow the battery to rest for one
hour before taking it into service.
6. For standstill periods of more than one month you should
always disconnect the battery. Do not forget to perform reg-
ular open-circuit voltage measurements.
