Three-pack replacement batteries

Kastar supplies three lithium-ion batteries rated at 7.4 V and 2300 mAh each, matching the NP-FM50 and NP-FM55H form factor. The pack is intended for owners of compatible Sony Handycam and Cyber-shot models who want spare power without buying single cells.

Built-in protection circuits

Each cell includes over-charge, over-discharge, over-voltage, over-current and over-heating safeguards and meets UL1642 and CE safety standards. The batteries slot directly into the camera or the listed Sony BC-VM50, BC-VM10 and BC-V615 chargers, so no extra adapters are required for daily charging.

17 Wh capacity per battery

The 17 Wh rating determines how long a single charge will last in supported camcorders and cameras; buyers who need more runtime per cell should look for higher-capacity alternatives.

Questions about this item

Does the 7.4 V 2300 mAh lithium-ion pack fit the NP-FM50 and NP-FM55H form factor?

Yes, each cell matches the NP-FM50 / NP-FM55H size and voltage so it slides into the same battery compartment.

What physical space is needed for one battery?

Each unit measures 3 by 2 by 3 inches, so allow that volume in the camera body or charger bay.

How are the batteries installed and what step is often missed?

Insert each pack with the contacts facing the camera terminals until it clicks; the step users skip is fully seating the latch so the protection circuit engages.
