Replacement Battery and USB Charger Kit

This kit provides a lithium-ion battery rated at 7.4 volts and 2300 milliampere-hours together with a dual-slot charger. It is intended for owners of compatible Sony Handycam and Cyber-shot models who need a spare power source and a convenient way to recharge it. The charger accepts Micro-USB or USB Type-C input and includes a Micro-USB cable.

Sustained Charging Behaviour

The charger can replenish two batteries simultaneously, each slot delivering 800 milliamperes at 8.4 volts. An intelligent LCD panel shows real-time charging status and remaining capacity for both cells. Input power is rated at 5 volts, 2 to 3 amperes, 15 watts, allowing continuous operation from standard USB power adapters or power banks.

Thermals, Noise and Power Draw

The charger operates silently with no moving parts, drawing up to 15 watts from the USB source during dual-battery charging. The lithium-ion battery chemistry produces minimal heat during normal discharge in a camcorder. No active cooling is required for either component under typical indoor use.

Questions about this item

Does the LTD2 charger generate noticeable heat or noise when charging two NP-FM50 batteries continuously all day?

The LTD2 charger runs from a 5 V 2-3 A USB supply and delivers 8.4 V at 800 mA per slot, so heat and fan noise stay low during extended dual-battery charging sessions.

What power source must I already have to run the LTD2 charger with its Micro-USB or Type-C input?

Any 5 V USB source rated at 2-3 A — such as a wall adapter, power bank or laptop port — and the included Micro-USB cable are all that is required.

Will the NP-FM50 battery work in my older Sony DCR-TRV10 camcorder alongside the original NP-FM30 pack?

Yes, the NP-FM50 is listed as compatible with the DCR-TRV10 and replaces the NP-FM30, NP-FM50, NP-FM55H and related InfoLITHIUM packs used in that model.
