Two-Pack Lithium-Ion Replacement

This two-pack supplies 7.4 V 2300 mAh lithium-ion cells that replace Sony NP-FM and NP-QM series batteries. Each unit stores 17 Wh and fits the original battery compartment without modification. The pair suits owners of compatible Handycam, Cyber-shot and MVC models who want a ready spare.

Built-In Protection and Charger Compatibility

Cells meet UL1642 and CE safety standards and include over-charge, over-discharge, over-voltage, over-current and over-heating circuits. The batteries charge in Sony BC-VM50, BC-VM10 and BC-V615 chargers, so existing charging workflows stay unchanged. Compact 3 by 2 by 2 inch dimensions keep the kit easy to stow in a camera bag.

Direct Substitute for Aging Originals

The pack replaces depleted Sony NP-FM30, NP-FM50, NP-FM55H, NP-QM71D, NP-QM91D and related packs used in listed CCD-TRV, DCR, DSC and MVC cameras. It is not for devices that require a different voltage or form factor. The upgrade is worth it when original cells no longer hold a full day’s charge.

Questions about this item

What voltage does the 7.4 V Li-ion pack deliver to the camera?

Each cell provides a nominal 7.4 V output that matches the original Sony NP-FM50 and NP-FM55H specifications.

What are the physical dimensions of one battery?

Each unit measures 3 × 2 × 2 inches, fitting the same compartment as the Sony NP-FM50, NP-FM55H and listed compatible models.

How do I charge the two packs with a Sony BC-VM50 charger?

Insert one battery at a time into the BC-VM50, BC-VM10 or BC-V615 charger; the built-in protection circuit stops charging automatically when full.
