Kastar NP-FM50 Replacement Battery

The Kastar NP-FM50 is a lithium-ion power cell built to replace Sony NP-FM50 and NP-FM55H packs in compatible Handycam and Cyber-shot models. It delivers 7.4 volts and a rated capacity of 2300 milliampere-hours, giving 17 watt-hours of energy. The pack suits owners of older Sony camcorders who need a fresh, safety-tested cell for continued use.

Lithium-Ion Chemistry and Voltage Limits

The cell uses standard lithium-ion chemistry with a nominal 7.4 V output, so it must only be charged in devices or chargers designed for that voltage. Over-charge, over-discharge, over-voltage, over-current and over-heating protection circuits are built into the pack to meet UL1642 and CE safety requirements. Users should avoid third-party chargers that lack matching voltage regulation.

2300 mAh Capacity Decides Suitability

The single specification that determines fit is the 2300 mAh capacity at 7.4 V; cameras expecting a higher or lower milliampere-hour rating may show reduced run-time or inaccurate fuel-gauge readings. Buyers who need extended recording sessions beyond what this capacity provides should look for a higher-rated compatible pack.

Questions about this item

Should I choose the NP-FM50 or NP-FM55H version for my camera?

This single pack replaces both Sony NP-FM50 and NP-FM55H batteries, so one version covers either original model without needing to select between them.

What does the 2300mAh capacity actually deliver in my camcorder?

At 7.4V the cell stores 17 Wh, giving roughly the same runtime as the original Sony NP-FM50 or NP-FM55H packs in compatible Handycam and Cyber-shot models.

Does the built-in protection circuit limit charging with Sony BC-VM50 or BC-VM10 chargers?

No — the over-charge, over-discharge, over-voltage, over-current and over-heating safeguards work with the listed Sony BC-VM50, BC-VM10 and BC-V615 chargers without restricting normal charge cycles.
