Battery 4250mAh LI-Polymer (BP42 compatible)

This 4250 mAh lithium-polymer battery is designed as a replacement for the BP42 battery. It is a generic OEM battery without its own brand name and weighs about 50 g. The cell stores electrical energy and releases it to the device it is intended for whenever power is needed.

Lithium-polymer batteries belong to the lithium-ion family and offer a high energy density in a light, thin form. That slim construction makes them well suited to compact devices. They can be recharged repeatedly and do not suffer from the classic memory effect, so their capacity holds up well under regular charging.

The 4250 mAh capacity determines how long the device runs on a single charge. Like all rechargeable cells, this battery gradually loses performance over time, and its service life depends on the number of charge cycles and how it is cared for. Before fitting it, check that its compatibility details match your device.
