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 0 °C and 45 °C. As an example,
do not leave the battery in the car in summer.
A significantly reduced working period after
charging indicates that the battery is used and
must be replaced.
Observe the notes for disposal.
