Button Cell - Rechargeable Variants

Rechargeable Variants

Most button cell batteries are not rechargeable due to the inferior capacity and/or high self-discharge rate of rechargeable batteries. There are a few rechargeable button cell batteries, such as lithium-ion rechargeable batteries intended to replace CR-series lithium manganese dioxide batteries in devices with relatively high current consumption or some devices with solar panels which can be used to keep the battery charged under certain circumstances.

Rechargeable NiCd button cells were often components of the backup battery of older IBM PC compatibles as well as Amiga computers.
