Compatible Replacement Battery

This Cameron Sino DS-CS-SAZ100MC lithium-ion cell replaces the Sony NP-BY1 pack in Action Cam Mini models AZ1, HDR-AZ1, HDR-AZ1/W, HDR-AZ1VR and HDR-AZ1VR/W. It supplies 3.7V and 640mAh for 2.39Wh of energy. The black housing measures 38.20 x 26.82 x 7.34 mm and weighs approximately 0.64Ah equivalent. It arrives new and ready to use.

Who Should Skip This

Owners of other Sony camcorders or Alpha cameras need a different form factor and voltage. Users who require longer runtimes than a single 640mAh cell provides should consider carrying spares. Videographers needing in-camera USB charging must verify their specific model supports it with third-party cells. This unit only fits the listed Action Cam Mini series.

Capacity and Voltage Rating

The decisive figure is the 640mAh capacity at 3.7V, yielding 2.39Wh. Confirm your device accepts the NP-BY1 part number before ordering. This capacity determines recording time per charge. No other specification overrides this compatibility check.
