Two-pack Li-ion camera batteries

This twin pack delivers two 7.4 V 2300 mAh lithium-ion cells rated at 17 Wh each. They replace Sony NP-FM50 and NP-FM55H packs and fit a long list of Cyber-shot, Handycam and DCR models. Photographers and videographers who need a ready spare for extended shoots will find the pair convenient.

Compact cells with built-in protection

Each battery measures 3 by 2 by 2 inches and includes over-charge, over-discharge, over-voltage, over-current and over-heating safeguards that meet UL1642 and CE standards. The cells slot directly into the camera or into compatible Sony BC-VM50, BC-VM10 and BC-V615 chargers, so no extra adapters are required for daily use.

Upgrade from lower-capacity originals

The 2300 mAh rating exceeds the capacity of the original NP-FM30, NP-FM50 and NP-QM50 packs, giving longer run time per charge. The jump is worth it when you regularly drain a single battery during events, travel or long recording sessions. Buyers who need higher voltage or a different form factor should look elsewhere.
