Working Advice
Recommendations for Optimal Handling of the Battery
Protect the battery against moisture and water.
Store the battery only within a temperature range between
–20 °C and 50 °C. As an example, do not leave the battery in
the car in summer.
A battery that is new or has not been used for a longer period
does not develop its full capacity until after approx. 5 charg-
ing/discharging cycles.
A significantly reduced working period after charging indi-
cates that the battery is used and must be replaced.
Observe the notes for disposal.
