Note
A too high storage temperature leads to faster self-discharge and a premature ageing of the
battery system.
The storage temperature must be in the range 0 °C … +40 °C.
The optimum storage
temperature is in the range +10 °C … +20 °C.

Storage with permanent float charge
Float charge means: Charge permanent with current limitation of the nominal charge current

/5h with following constant voltages:
•
2.25 V per cell in case of 2 V single cells
•
6.75 V per block in case of 6 V blocks
•
13.5 V per block in case of 12 V blocks
7.2.
Storage with regularly recharge
Regularly recharge means: Charge the battery system for 24 hours with current limitation of
the nominal charging current I

/5h with following constant voltages:
•
2.35 V per cell in case of 2 V single cells
•
7.05 V per block in case of 6 V blocks
•
14.1 V per block in case of 12 V blocks
Following intervals must be observed:
•
Every 6 months, if the average storage temperature is ≤ +20 °C
•
Every 3 months, if the average storage temperature is in the range of +20 °C … +30 °C
•
Every 6 weeks, if the average storage temperature is in the range of > +30 °C
Note the respective loading processes in a log.
