Four lithium-ion batteries and dual-slot USB charger

This pack supplies four 7.4 V lithium-ion cells rated at 2400 mAh each, together with a compact LTD2 charger that accepts both Micro-USB and Type-C power. It is intended for photographers using Sony Alpha DSLR and SLT bodies that take the NP-FM500H form factor and who want a lightweight spare-power kit for day-long shoots.

7.76 Wh per cell matches the NP-FM500H specification

Each battery delivers 7.76 Wh at the nominal 7.4 V, matching the original Sony NP-FM500H and NP-FM500HN cells. The charger outputs 8.4 V at 800 mA per slot so two packs reach full charge in parallel without needing a proprietary AC adapter.

Steady 800 mA output keeps temperatures low during

The charger maintains a constant 800 mA per bay whether one or two batteries are inserted, avoiding the current taper that causes heat build-up in rapid single-slot units. LCD read-outs show individual capacity so you can rotate packs through a wedding or event without guessing remaining runtime.

Questions about this item

How long will a 2400 mAh 7.4 V battery last in my Sony DSLR-A700?

The 7.76 Wh cells give roughly the same shooting time as the original NP-FM500H; actual frames depend on LCD use, flash and temperature.

What does the 5 V 2–3 A USB input on the LTD2 charger limit?

It caps each bay at 800 mA, so two batteries charge together at that rate from any 15 W USB source.

Will the 5 by 3 by 3 inch pack fit in my camera bag beside an A900 body?

The four batteries and dual charger occupy a small 5×3×3 in block that slides into most accessory pockets.
