Three-pack Li-ion for Sony Alpha DSLRs

This Kastar NP-FM500H set supplies three 7.4 V 2400 mAh lithium-ion cells rated at 17.76 Wh each. They fit the Sony NP-FM500H slot used across the Alpha A200 through A900 and SLT-A57 to A77 II families. Photographers who need several ready spares for long shooting days can carry all three in a compact bag.

Steady output across extended sessions

Each cell delivers its rated capacity without the sharp voltage drop seen in lower-grade packs after a few dozen shots. The built-in protection circuit guards against over-charge, over-discharge, over-voltage, over-current and over-heating so the camera keeps running predictably from the first frame to the last. Cycle life benefits from the consistent charge management.

Low heat and safe charging on standard chargers

The chemistry and protection design keep cell temperature modest during normal capture and playback, even when the camera is used continuously. Charging on the Sony BC-VM10 or AC-SQ950 proceeds at the charger's standard rate with no extra fan noise from the battery itself. UL1642 and CE marks confirm the safety baseline for everyday handling.
