Cameron Sino M3AEBT 500mAh 3.7V cell phone battery

Replacement cell for Momentum True Wireless headsets

The Cameron Sino M3AEBT is a 3.7V 500mAh lithium cell built to the original 36.00 x 25.00 x 6.00mm footprint. It fits the Momentum 3 Wireless, Momentum True Wireless 2 and related models listed under part number AHB702535PCT-01. The pack weighs 10.2g and carries ISO9001, RoHS and CE certification. Buyers who need a higher-capacity pack or a different form factor cannot use this cell.

Thermal behaviour and power profile

Rated at 1.85Wh, the cell delivers the same voltage and capacity as the factory unit, so discharge curves and run-time remain unchanged. Normal use inside the sealed earbud enclosure keeps temperatures well below the 60 140 storage limit. No active cooling is required and the protection circuit guards against over-charge, over-discharge, over-voltage and short-circuit. Users who expect the battery to power larger devices will find the energy reserve insufficient.

Included hardware and installation notes

The retail box contains one AAA-size cell wrapped in shock-absorbing foam for transit protection. A fully decoded chip ensures the headset recognises the pack immediately without firmware updates. The manufacturer notes that two or three full charge-discharge cycles bring the cell to peak capacity. Installers who cannot access the internal connector or lack suitable tools will not be able to complete the swap.
