Compatible replacement for 70mai Pro dashcam

This Cameron Sino lithium-ion cell is built to the original specifications for the 70mai Pro dash camera carrying part number HMC1450. It delivers 1000mAh at 3.70 volts and fits the exact 53.00 x 14.50 x 14.20 millimetre footprint. A decoded chip ensures the camera recognises the pack and reports remaining capacity accurately.

Suits owners needing a fresh power cell for daily

Drivers who rely on continuous loop recording or parking-mode surveillance will regain full runtime with this new pack. The battery is not intended for cameras outside the 70mai Pro series, nor for devices that require a different voltage, capacity or physical layout. Buyers who need a multi-cell pack or a higher energy rating should look elsewhere.

1000mAh capacity at 3.70 volts

The single figure that decides fitment is the 1000mAh / 3.70Wh rating matched to the HMC1450 part number. If the original battery label shows those values and the dimensions match 53.00 x 14.50 x 14.20 millimetres, this replacement will slot in and power the dashcam as designed.
