E-bike batteries should be stored in a dry, well-ventilated place. A basement room or garage is ideal. The batteries should not be stored in the immediate vicinity of heat sources such as radiators. Direct sunlight should also be avoided. Make sure that the room has a smoke detector. Small metal objects should also be kept away from the e-bike battery. These include paper clips, coins, keys, nails and screws, for example. These could cause the contacts to be bridged, resulting in a short circuit between the battery contacts.
Should I store my e-bike battery fully charged?
No, a bicycle battery should not be fully charged before being stored for a longer period of time. Charging to approx. 60% is sufficient. Check the charge level again after six months. If it falls below 30%, a “recharge” is recommended. Please do not store an empty bike battery. This is because lithium-ion batteries discharge themselves over time. During prolonged storage, they can become discharged (deep discharge) that they have to be replaced.
