Replacement for Sony NP-FM series

This Kastar lithium-ion pack replaces a long list of Sony NP-FM, NP-QM and NP-FM90-type batteries used in Handycam camcorders and Cyber-shot cameras. It delivers 7.4 V and 2 300 mAh in a single-cell format that fits the original battery compartment without modification.

Sustained shooting performance

The 17 Wh cell maintains a steady voltage curve during extended recording sessions, avoiding the sudden drop-off seen in lower-capacity packs. Built-in protection circuits guard against over-charge, over-discharge, over-voltage, over-current and over-heating so the pack remains stable under continuous load.

Upgrade from lower-capacity originals

Users moving from the 1 300 mAh NP-FM30 or similar entry-level packs gain roughly 75 % more runtime per charge, reducing the need to carry spares on long shoots. The improvement is most noticeable on models that drain batteries quickly, such as the DCR-TRV350 or DSC-F828.
