Kastar NP-FM500H 2-pack for Sony Alpha cameras

This two-battery set replaces the Sony NP-FM500H and fits a wide range of Alpha DSLR and SLT bodies from the A200 through the A900 series. Each cell is a 7.4V 2400mAh lithium-ion unit rated at 17.76 Wh. The pack suits photographers who want a ready spare without paying original-brand prices.

Upgrade from worn or low-capacity originals

Swapping an ageing NP-FM500H that no longer holds a full charge restores shooting time for long sessions or video work. The jump is worth it when your current battery drains quickly or when you regularly carry only one cell and risk missing shots. Built-in protection circuits guard against over-charge, over-discharge, over-voltage, over-current and over-heating.

Check your camera and charger compatibility

Confirm your body appears in the supported model list covering Alpha A200, A300, A350, A450, A500, A550, A560, A580, A700, A850, A900 and SLT-A57, A58, A65, A68, A77, A77II series. Verify you can charge these cells with a Sony BC-VM10 or AC-SQ950 charger. Buyers needing a different voltage, capacity or form factor should look elsewhere.

Questions about this item

Will the 2.2 by 1.5 by 1.6 inch NP-FM500H fit the Sony A550 battery compartment?

Yes, the NP-FM500H matches the original Sony dimensions and locks into the A550, A560 and every other listed Alpha body.

What is the correct way to charge these 7.4 V 2400 mAh packs and what step do users often skip?

Charge with the Sony BC-VM10 or AC-SQ950 charger until the indicator shows full; the step often skipped is completing that first full charge before shooting.

When will the lithium-ion cells in this two-pack need replacing?

After roughly 300 to 500 full cycles the capacity drops noticeably; swap the pack when run-time falls below your shooting needs.
