Kastar NP-FM500H Lithium-Ion Battery

The Kastar NP-FM500H is a 7.4V lithium-ion replacement battery rated at 2400mAh and 17.76 Wh. It fits a wide range of Sony Alpha and SLT cameras including the A77 II, A99 and A580 series. Photographers who need a spare or replacement power source for long shooting days will find it compatible with the listed models.

Sustained Capacity and Protection

The cell delivers its rated capacity over extended use rather than only in short bursts. Built-in circuitry guards against over-charge, over-discharge, over-voltage, over-current and over-heating during continuous operation. This protection helps maintain consistent output and supports a longer overall cycle life for the pack.

Thermals and Safety Standards

The battery meets UL1642 and CE safety standards, limiting temperature rise during normal camera use. No active cooling is required and the pack runs silently inside the camera body. Power draw follows the camera's own demand profile without adding audible noise or excess heat.
