Battery FAQs

The battery does not work

Some batteries need to be turned on before use.

The battery can’t be charged

- The indicator on the charger turns green right after connecting it to the battery. It won’t turn red, but the battery is empty.  The indicator on the charger turns green if the battery is fully charged, if there is a problem concerning the charging fuse or if the battery is deeply discharged.  - Try an alternative socket.  - Replace charger - Check charging fuse. For most batteries it is possible to reach the charging fuse from the outside of the battery case. (B1U, I5-36V. R3S). If the battery does not have a cover with the inscription "FUSE" (e.g. I5-48Volt), the battery must be sent in and replaced, as an internal charge fuse can only be changed by qualified personnel.

Attention! Never ask the customer to open the battery case!
