Four-battery kit for Sony Alpha DSLR and SLT bodies

The pack contains four 7.4 V 2400 mAh lithium-ion cells rated at 17.76 Wh each, plus an AC wall charger. It replaces the Sony NP-FM500H and works with Alpha models from the 200 series through the 900 series and SLT-A57 to SLT-A77 II.

Charger limited to 600 mA output per cell

The wall unit accepts 100-240 V AC input and delivers 8.4 V DC at 600 mA, so a fully depleted 2400 mAh battery needs roughly four hours to reach the green-light indication. Only one battery charges at a time in the single bay.

Foldable plug eases travel but single bay slows

The flat pins fold flat for packing, yet swapping four cells sequentially means a full set change takes most of a day. Users who shoot long sessions should plan for overnight charging or carry a second charger.
