5.1.1 Charging cycles
A cycle is counted when the battery has been discharged by the capacity set at the cycle depth and
then recharged.
With the number of cycles they are able to estimate the life of your battery. Standard starter
batteries have a lifespan of 30-50 cycles, while cycle batteries have a lifespan of up to 300 cycles if a
modern battery charger is used. These values can only be achieved with proper care and deteriorate
rapidly in case of mistreatment.
5.1.2 Deep discharges
Every complete discharge up to the lower voltage limit (9-11.5 V depending on the load) is
considered a deep discharge. Deep discharges should be avoided at all costs as they damage the
battery and premature capacity loss and lifetime reduction are expected for most battery types.
However, should a deep discharge occur, the battery must be recharged immediately to avoid
further damage.
5.1.3 Mean depth of discharge
The average depth of discharge indicates the amount of capacity by which the battery group was
discharged on average in the past 10 cycles. From this it is possible to read the cycle load of the
battery and to deduce a conclusion on the battery life.
5.1.4 Reset the counters
If a new battery pack is used, the number of cycles, the deep discharges on and the total capacity
counter must be set to zero. To do this, the upper battery "000" key must be pressed and
subsequently confirmed by PIN entry (PIN Default 1234). The Min / Max counters can be reset by
pressing the lower "000" key followed by the PIN entry (PIN Default 1234).
