Four-pack replacement for Sony camcorders

This set contains four Kastar lithium-ion batteries rated at 7.4 V and 2300 mAh, delivering 17 Wh each. They replace Sony NP-FM30, NP-FM50, NP-FM55H, NP-QM71D, NP-QM91D and related packs. The cells suit Handycam, Cyber-shot and MVC models listed by the supplier.

Works with Sony chargers and listed cameras

The batteries charge in Sony BC-VM50, BC-VM10 and BC-V615 chargers without an adapter. They power the compatible camcorders and cameras directly, freeing you from carrying a single original pack. No other chargers or camera models are supported by this pack.

Steady output with built-in protection

Internal circuits guard against over-charge, over-discharge, over-voltage, over-current and over-heating during extended recording sessions. The lithium-ion chemistry maintains voltage through long takes rather than fading after a short burst. Cycle life benefits from the protection design.
