Two-pack replacement for Sony NP-BG1 and NP-FG1

This pack contains two 3.7 V lithium-ion batteries rated at 1600 mAh each. They are designed for Sony Cyber-shot cameras that accept the NP-BG1 or NP-FG1 form factor. The set is aimed at photographers who want spare cells for longer shooting sessions without relying on a single original pack.

Slim USB charger powers from multiple sources

The included charger accepts power from a wall adapter, car charger, power bank or PC via its USB input. It charges one battery at a time and uses an LED that glows red while charging and green when full. The bundle also supplies a short USB cable, so no separate AC adapter is required to start charging.

Compact cells weigh 1.0 oz each

Each battery measures 1.63 × 1.39 × 0.32 in and weighs approximately 1.0 oz, adding minimal bulk to a camera bag. The charger draws power only while a cell is inserted, so idle consumption is negligible. The pack is not compatible with slimmer Sony types such as NP-BN1, NP-BK1 or NP-FR1, so owners of those models must look elsewhere.

Questions about this item

How long will the 1600mAh capacity last during continuous shooting?

The 1600mAh lithium-ion cells deliver stable power for extended sessions; actual runtime depends on the camera model and usage pattern.

Does the slim USB charger get hot or noisy when charging both batteries back-to-back?

The charger runs silently with no fan; it may become slightly warm during prolonged charging, which is normal for compact USB designs.

Which Sony camera models must I already own for these NP-BG1/NP-FG1 batteries to fit?

Compatible cameras include Cyber-shot DSC-H, HX, N, T and W series models such as DSC-H3, HX5V, N1, T20 and W30 — check your original battery label for NP-BG1 or NP-FG1.
