Two NP-FM500H batteries with foldable AC charger

This pack supplies two lithium-ion batteries rated at 7.4 V and 2400 mAh each, plus a wall charger with a foldable flat plug. The charger accepts 100 to 240 V input and delivers 8.4 V at 600 mA, showing red while charging and green when full. Photographers using compatible Sony Alpha and SLT bodies gain a spare set that charges from any mains socket.

Replaces Sony NP-FM500H cells

Owners of Alpha 57, 58, 65, 68, 77, 77 II or 99 models, as well as older DSLR-A200 through A900 bodies, can swap depleted originals for fresh 17.76 Wh units. The upgrade is worthwhile when the original pack no longer holds a full day of shooting or when a second charger is needed for travel.

Charger limited to 600 mA output per cycle

At 600 mA the wall unit needs several hours to restore a 2400 mAh cell, so rapid turnaround between shoots is not possible. The foldable pins aid packing but the single-channel design charges one battery at a time. Users needing faster or simultaneous charging must look elsewhere.

Questions about this item

What are the physical dimensions of each battery in the pack?

Each battery measures 3 by 2 by 2 inches, fitting the Sony NP-FM500H form factor used in Alpha 77II and Alpha 99 bodies.

How do you install the charger and what step is often missed?

Plug the foldable flat-pin charger into a 100 to 240V AC outlet, insert one or both batteries, and wait for the LED to turn green; people often pull the battery while the light is still red.

When will the 2400mAh Li-Ion cells need replacing?

After roughly 300 to 500 full charge cycles the capacity drops below 80 percent of 17.76 Wh, so plan on new batteries every two to three years with regular use.
