Two-Pack Replacement Battery

This two-pack of 7.4V lithium-ion cells replaces Sony NP-FM50 and NP-FM55H batteries for a wide range of Handycam and Cyber-shot models. Each cell delivers 2300 mAh and 17 Wh, giving extra recording time for events, travel or family video. Built-in protection circuits guard against over-charge, over-discharge, over-voltage, over-current and over-heating.

Capacity and Practical Headroom

At 2300 mAh the pair comfortably powers a camcorder through a wedding ceremony, a school play or a day of holiday clips without a mid-event swap. Extended sessions such as multi-hour sports matches or back-to-back interviews will drain the cells and require a recharge or a third battery. The 7.4 V output matches the original spec so the camera’s fuel gauge remains accurate.

Upgrade Path and When It Pays Off

Users moving from aged NP-FM30 or NP-QM50 packs that no longer hold a full charge will see an immediate runtime gain. The jump is worthwhile whenever the original battery dies before the memory card fills. Shooters who need all-day power without access to a charger should add a third cell or a higher-capacity alternative.

Questions about this item

Will the 7.4 V 2300 mAh packs work in my DCR-TRV140 camcorder?

Yes, the batteries are listed as direct replacements for the DCR-TRV140 and the full TRV series shown in the compatibility list.

How can I confirm the cells are charging correctly after I insert them?

The built-in protection circuit prevents over-charge and over-discharge; the camcorder’s battery indicator will show normal charge progress when the pack is seated.

Does the two-pack include a charger or only the batteries?

The pack contains two lithium-ion batteries only; a compatible Sony BC-VM50, BC-VM10 or BC-V615 charger must be supplied separately.
