Recommendations for Optimal Handling of the Battery
Protect the battery against moisture and water.
Only store the battery within a temperature range of −20 to 50 °C. Do not leave the bat-
tery in your car in the summer, for example.
Occasionally clean the ventilation slots on the battery using a soft brush that is clean and
dry.
A significantly reduced operating time after charging indicates that the battery has de-
teriorated and must be replaced.
