Four-pack NP-FM500H with dual USB charger

The set supplies four 7.4 V lithium-ion cells rated at 2400 mAh each, plus an LCD charger that powers two batteries simultaneously from any 5 V USB source. Photographers using Sony Alpha DSLR or SLT bodies listed in the compatibility data gain a ready spare pool for long shooting days.

Suits owners of listed Sony models needing

The bundle covers DSLR-A200 through DSLR-A900 and SLT-A57 through SLT-A77II bodies that accept NP-FM500H cells. Users whose cameras require a different battery form factor or who need AC mains charging without a separate USB adapter should look at other kits.

Charges two batteries at once from 5 V USB

The LTD2 charger delivers 8.4 V at 800 mA per slot and shows capacity on its LCD while drawing 5 V at up to 3 A through Micro-USB or Type-C ports. This single spec decides whether the kit fits a workflow built around portable power banks rather than wall outlets.

Questions about this item

Should I choose the four-battery pack or a smaller set for my Sony A580?

The pack includes four 2400mAh NP-FM500H batteries and one dual-slot charger, giving you enough spares for a full day of shooting without swapping.

What does the 7.76 Wh rating mean when the battery is inside my A700?

At 7.4 V the cell stores 7.76 Wh, which is the same as 2400 mAh and typically delivers several hundred shots per charge on compatible Alpha bodies.

How fast does the LTD2 charger actually fill a battery over its USB-C or Micro-USB ports?

The charger draws up to 15 W from a 5 V 2–3 A source and outputs 8.4 V at 800 mA per slot, so two batteries charge simultaneously at that rate.
