Two-pack replacement batteries for Sony camcorders

This pack contains two Kastar lithium-ion batteries built to replace Sony NP-FM50 and NP-FM55H cells. They supply 7.4 V and 2300 mAh for compatible Handycam, Cyber-shot and DCR models. The pair lets you keep one charging while the other shoots.

7.4 V 2300 mAh lithium-ion chemistry

Each cell delivers 17 Wh at the nominal voltage your camcorder expects. The lithium-ion chemistry matches the original Sony specification so the camera’s fuel gauge and charge logic work without adaptation. No other voltage or capacity is offered in this listing.

Drop-in fit with built-in protection circuits

The batteries slide into the same compartment and charge on Sony BC-VM50, BC-VM10 or BC-V615 chargers. Integrated over-charge, over-discharge, over-voltage, over-current and over-heating guards protect both the pack and the camera. Users who need a different form factor or higher capacity must choose another model.

Questions about this item

What does the 2300 mAh rating mean for actual recording time on my camcorder?

The 2300 mAh capacity at 7.4 V delivers roughly 17 Wh of energy, which typically powers compatible Sony Handycam models through several hours of continuous DV recording before needing a recharge.

Does the 7.4 V lithium-ion chemistry limit which chargers I can use?

These cells are designed for Sony BC-VM50, BC-VM10 and BC-V615 chargers; using other chargers that do not match the 7.4 V lithium-ion profile can prevent proper charging or trigger the built-in protection circuit.

Will the 3-by-2-by-2-inch pack fit the battery compartment of a DCR-TRV30?

Yes, the NP-FM50/NP-FM55H form factor matches the original Sony battery dimensions, so it slides directly into the DCR-TRV30 and the other listed Handycam and Cyber-shot models without adapters.
