Replacement Battery and Wall Charger Kit

This kit supplies a 7.4 V lithium-ion battery rated at 2300 mAh together with an AC wall charger. It targets owners of compatible Sony Handycam and Cyber-shot models who need a spare power source. The foldable flat plug makes the charger easy to pack for travel or daily use.

Sustained Use Behaviour

The charger accepts 100 to 240 V AC input and delivers 8.4 V at 600 mA, so a fully depleted cell takes several hours to reach full capacity. A red LED shows active charging while a green LED signals standby or completion, allowing the user to monitor progress without guesswork.

Installation and Common Issues

The battery slides into the camera compartment exactly like the original NP-FM50, and the charger plugs directly into a wall outlet with no cables required. Problems usually arise when the camera model is not on the supported list, resulting in a poor fit or no charge indication.

Questions about this item

How warm does the NP-FM50 battery get when the camcorder runs all day?

The 7.4 V lithium-ion cell produces little heat during normal recording; the charger’s 600 mA output keeps temperature low while topping it up.

What must I already own so the foldable-plug AC charger can power the battery?

A standard 100–240 V wall outlet is all that is required; the charger accepts worldwide mains voltage directly.

Will this NP-FM50 pack work in my older DCR-TRV140 that originally used an NP-FM50?

Yes — the battery replaces Sony NP-FM50 and NP-FM55H packs and fits every camcorder and camera listed as compatible with those models.
