Two-Pack Replacement Battery for Sony DSLR

This Kastar NP-FM500H twin-pack supplies two 7.4 V 2400 mAh lithium-ion cells rated at 17.76 Wh each. They replace the Sony NP-FM500H and fit a long list of Alpha and SLT bodies from the A200 through the A900 series. Photographers who need spare power for extended shoots can carry both units in a bag.

Simple Drop-In Installation With Built-In Protection

Each cell slides into the camera battery compartment exactly like the original pack and charges on the Sony BC-VM10 or AC-SQ950 charger. Integrated circuits guard against over-charge, over-discharge, over-voltage, over-current and over-heating. The only common issue is forgetting to fully charge both packs before a long session.

Verify Your Camera Model Before Ordering

Check that your body appears in the compatible list covering Alpha 200, 300, 350, 450, 500, 550, 560, 580, 700, 850, 900, 57, 58, 65, 68, 77 and 77II variants. These batteries do not fit Sony mirrorless E-mount models or older InfoLithium types such as NP-FW50. Confirm the NP-FM500H designation on your current pack or charger.

Questions about this item

How do I confirm the batteries are charging and holding a charge correctly?

Insert a battery into a Sony BC-VM10 or AC-SQ950 charger; the charger indicator should show charging progress and then a full-charge signal. In the camera, the battery info screen should report 7.4 V and capacity near 2400 mAh after a full cycle.

What comes in the package and do I need a separate charger?

The pack contains two Kastar NP-FM500H lithium-ion batteries (7.4 V, 2400 mAh, 17.76 Wh each). A charger is not included; you must use a compatible Sony BC-VM10 or AC-SQ950 charger or the camera's own charging function.

Which Kastar NP-FM500H version should I choose for my Sony Alpha 77?

This single 2-pack version (part BA-2B-FM500H-M) is the only one listed; it replaces the Sony NP-FM500H and fits the Alpha 77, SLT-A77, SLT-A77V and related models directly.
