Three-pack lithium-ion power for Sony Handycam

This set delivers three 7.4 V 2300 mAh lithium-ion cells that replace the Sony NP-FM50 and NP-FM55H packs used across a long list of Handycam and Cyber-shot models. Each cell stores 17 Wh and includes built-in protection against over-charge, over-discharge, over-voltage, over-current and over-heating. The UL1642 and CE-tested chemistry targets owners who want a ready supply of compatible power without sourcing single units.

Steady output during long recording sessions

The protection circuit maintains stable voltage across extended takes, so the camcorder does not shut down early when the battery warms under continuous use. Three packs let you rotate cells while shooting events, interviews or travel footage, keeping the camera running without waiting for a single pack to recharge. The lithium-ion chemistry holds charge between uses better than older nickel-based packs.

Replaces ageing original packs

This bundle suits owners whose factory NP-FM50 or NP-FM55H cells no longer hold a full charge, or who have been using cheaper copies that fade quickly. It is not for users who need higher-capacity NP-FM70 or NP-FM90 series packs, nor for cameras that require the newer InfoLithium M-series interface.

Questions about this item

How much heat does the 7.4 V 2300 mAh pack generate during all-day recording?

The lithium-ion cells include over-heating protection and meet UL1642 and CE safety standards, keeping temperature rise within safe limits for continuous use.

Which charger do I already need to recharge these NP-FM50 / NP-FM55H batteries?

They charge on Sony BC-VM50, BC-VM10 or BC-V615 chargers, so one of those models must be available.

Will the three-pack work in my older DCR-TRV260 and Cyber-shot DSC-F717 without issues?

Yes, the batteries replace Sony NP-FM50, NP-FM55H and NP-QM51 types used by both the DCR-TRV260 and the DSC-F717.
