Battery 4160mAh LI-Polymer (BM4R compatible)

This replacement battery is a 4160 mAh lithium-polymer cell compatible with the BM4R model. It is designed to replace a worn-out or faulty battery and restore the power supply of the matching device. The 4160 mAh capacity determines how long the battery can supply the device's electronics between charges.

Lithium-polymer batteries belong to the lithium-ion family and offer high energy density at a low weight. Their thin, flexible form suits slim devices where space is limited. They also avoid the memory effect, so their capacity does not drop noticeably over repeated charge cycles.

The battery weighs around 60 grams and is supplied as a single unit.
