4.4 CHARGING INSTRUCTIONS LEAD-ACID BATTERIES
The care and maintenance of the batteries is a crucial criterion for your batteries lifetime.
Improper maintenance, care and charging behavior can greatly reduce this, to irreparable
damage and premature catastrophic failure of the batteries. Leadacid
batteries should never be deeply discharged, but always be operated under the highest pos-
sible voltage. Deep-discharged batteries, for example, by total „run empty“ or by long storage,
without charging (eg over winter period) can force lead batteries getting sulfated and damage
the cells. This process is irreversible in many cases resulting in total loss of the battery.
Do not think you „waste“ many charge cycles by recharging the lead-acid battery more often
although this is not „emptied„ completely - this is totally wrong! For the specifi ed life by
charging cycles, so-called full cycles are meant. This means that if your battery is low 50% and
then fully recharged, this equates to a half charging cycle. Twice recharge accordingly means
full cycle then.
We therefore recommend recharging the battery from a discharge of 25%. But then always
until the charger completely fi nished loading. This guarantees reaching a maximum allowable
voltage of the cells.
During the winter or long-term storage of vehicles with lead-acid batteries, it is imperative
charging at least once a month until charging is complete.
