Kastar 1600mAh NP-BG1 replacement battery

This lithium-ion cell delivers 3.7V and 1600mAh capacity for Sony Cyber-shot cameras using the NP-BG1 or NP-FG1 G-Type pack. It fits a long list of DSC-H, HX, N, T and W series models and works with Sony BC-CSG chargers. The pack weighs 1.0 oz (28 g) and measures 1.63 × 1.39 × 0.32 in (41.4 × 35.3 × 8.1 mm).

Upgrading from a worn or lost original NP-BG1

Replace an ageing Sony NP-BG1 that no longer holds a full day’s charge or a missing pack on a used camera. The jump is worth it when your current battery drains quickly during extended shooting or video recording. This cell restores the original runtime without requiring a new charger.

Verify your camera uses the G-Type NP-BG1 before

Check the battery compartment label or manual for NP-BG1 or NP-FG1 compatibility; this pack will not fit slimmer Sony types such as NP-BK1, NP-BN1 or NP-FR1. Confirm you own or can access a Sony BC-CSG, BC-CSGD or BC-CSGE charger. Ensure the physical dimensions match the 1.63 × 1.39 × 0.32 in space in your camera.
