Safety and operating instructions

- 11 -



Unpredictable chemical processes might occur during the charging of storage batteries

that have not been used for a longer period of time (more than 6 months). In this case, it

is recommended to repeat the charging / discharging cycle at least 2 to 4 times.



If no improvement is achieved after several charging / discharging cycles, every storage

battery should be tested individually (by comparing the storage battery voltages, testing

by means of a cell charger etc.). It is very likely that only some of the storage batteries

have lost capacity. If one storage battery differs from the other ones, this might affect the

correct functioning of the entire storage battery block!



The effects described above must not be confused with the normal battery capacity

decrease over time. All rechargeable batteries (storage batteries) lose some of their

battery capacity when being charged / discharged several times. This information is

provided in the technical data specified by the battery manufacturer.
