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 un-
til after approx. 5 charging/discharging cycles.
A significantly reduced working period after charg-
ing indicates that the battery is used and must be
replaced.
Observe the notes for disposal.
