Two-Battery Kit with AC Charger

This kit supplies two lithium-ion cells rated at 7.4V and 2400mAh each, together with an AC wall charger that accepts 100 to 240V input and delivers 8.4V at 600mA. The bundle replaces Sony NP-FM500H batteries and the BC-VM10 or AC-SQ950 charger for a long list of Alpha DSLR and SLT bodies from the A200 through the A900 and the A57 to A77 II series. Photographers who need spare power for extended shoots can carry both cells and recharge from any mains socket.

Cool Running Charger with Foldable Plug

The charger uses a foldable flat pin that lies flush for storage and runs without a fan, so it adds no audible noise to a quiet studio or location bag. During a normal charge cycle the unit draws modest power from the wall and the LED shows red while charging, then green once each cell reaches full capacity. Because the output current is limited to 600mA, the batteries and the charger body stay at comfortable temperatures throughout the process.

Steady Output During Long Sessions

Each 17.76 Wh cell maintains a stable 7.4V nominal voltage through continuous shooting, video recording or live-view use without the voltage sag that can trigger early shutdowns. The charger replenishes both packs sequentially from a single outlet, allowing one battery to power the camera while the other recovers. This arrangement supports sustained workloads such as event coverage or time-lapse sequences where frequent swaps would be impractical.

Questions about this item

How do I install the Kastar NP-FM500H batteries and charger, and what step is often missed?

Insert each 7.4V 2400mAh battery into the charger slots, plug the foldable flat pin into a 100~240V AC outlet, and wait for the green LED before removing them.

What maintenance or replacement will the Kastar NP-FM500H batteries need later?

Lithium-Ion cells degrade with cycles; expect reduced runtime after several hundred charges and plan to replace both 17.76 Wh packs when they no longer hold a full 8.4V charge.

What limit appears first during sustained charging of the Kastar NP-FM500H kit?

The charger outputs 8.4V at 600mA, so each 2400mAh battery needs about four hours; heat from continuous cycling is the first practical limit.
