4-Pack Replacement for Sony Alpha DSLRs

This Kastar NP-FM500H set contains four lithium-ion batteries rated at 7.4V and 2400mAh each. They are direct replacements for the Sony NP-FM500H and work with a long list of Alpha DSLR and SLT bodies from the A200 through the A900 series. Photographers who need several spares for a full day of shooting can carry all four without buying single units repeatedly.

Thermal behaviour and power draw

Lithium-ion chemistry runs cool during normal camera operation and does not generate noticeable heat in the hand. Each cell stores 17.76 Wh of energy and includes built-in protection against over-charge, over-discharge, over-voltage, over-current and over-heating. The pack meets UL1642 and CE safety standards, so the camera draws power steadily without unexpected shutdowns or excessive drain.

What the four-pack changes for the user

Buying four batteries at once removes the need to rotate a single spare through a charger between sessions. The pack is compatible with the Sony BC-VM10 and AC-SQ950 chargers already owned by many Alpha users. Photographers who rely on extended video recording or continuous burst sequences gain enough reserve capacity to keep shooting without swapping cells mid-session.

Questions about this item

How do I install the NP-FM500H battery in my Sony A350, and what step do people often miss?

Slide the battery into the compartment until the latch clicks; the step many miss is pressing the lock lever fully so the pack cannot rattle loose during shooting.

What maintenance or replacement will the 2400mAh Li-ion cells need over time?

Expect capacity to drop after roughly 300–500 full cycles; store at about half charge in a cool place and replace the pack when run-time no longer covers a typical session.

What limit appears first during sustained use of the 7.4V 17.76Wh pack?

Heat buildup triggers the internal over-temperature protection, cutting output until the cells cool below the safety threshold.
