Warranty Exclusion: Please note that as batteries are "consumables" we only provide dead on arrival warranty.

The maximum capacity of all rechargeable batteries fades with time depending on application and usage patterns.

This is considered normal - therefore, a change in battery capacity is not covered under warranty.
