What the product is and who it is for

This two-pack supplies 7.2 V lithium-ion cells rated at 1550 mAh and 11.16 Wh each. They replace Sony NP-FV30, NP-FV50, NP-FV70 and NP-FV100 batteries in a long list of Handycam and FDR camcorders as well as DEV-series 3-D models. Videographers who need spare power for multi-hour shoots will find the pair convenient.

Build quality and daily use

Each cell carries UL1642 and CE safety marks and integrates protection against over-charge, over-discharge, over-voltage, over-current and over-heating. The pack works with Sony BC-TRV, BC-VH1 and AC-VQH10 chargers, so existing charging gear can be reused without buying new adapters. No mounting hardware is included; the batteries slot directly into the camera compartment.

Practical limits of the interface

Capacity is fixed at 1550 mAh, so runtime scales with the camcorder’s power draw and cannot be extended without adding more cells. The lithium-ion chemistry self-discharges slowly but still requires periodic top-ups during long storage. Users needing significantly longer runtimes per battery must consider higher-capacity NP-FV70 or NP-FV100 units instead.
