Cleaning battery packs

Wipe the battery contacts with a clean and lint free cloth to remove dirt, grease or any other material that may prevent a good electrical contact. If contacts are very dirty you can also wipe them using a soft pencil rubber (not hard erasers for ink!). If you feel that battery contacts aren’t still working properly, please contact your authorized dealer.

,Do not use liquid, alcohol or aerosol cleaners.
