Four lithium-ion batteries with wall charger

This kit supplies four NP-FM50 lithium-ion batteries and a matching AC wall charger. Each cell delivers 7.4 volts and 2300 milliampere-hours for a total energy rating of 17 watt-hours. The charger accepts 100 to 240 volt mains input and provides 8.4 volts at 600 milliamps output. A foldable flat plug keeps the adapter compact when packed.

Users of listed Sony Handycam and Cyber-shot models

The pack works with the Sony camcorder and camera series named in the compatibility list, including TRV, DCR, HC, PC, DSC and DVD models. It also replaces the NP-FM30, NP-FM55H, NP-QM50, NP-QM51, NP-FM70, NP-FM71, NP-QM71, NP-QM71D, NP-FM90, NP-FM91, NP-QM91 and NP-QM91D battery families. Photographers whose equipment uses a different battery form factor or voltage should choose a dedicated kit for that system.

7.4 V 2300 mAh lithium-ion chemistry

Every battery in the set is a 7.4 volt lithium-ion cell rated at 2300 milliampere-hours. The charger shows a red LED while charging and a green LED when the cell reaches full charge or stands by. This voltage and capacity combination is the deciding factor for matching the original Sony NP-FM50 specification.
