Cameron Sino B825M replacement battery 360mAh 1.33Wh 7.4V

Direct replacement for Voyager Focus headsets

This Cameron Sino B825M battery replaces the original Plantronics AHB403029 cell in Voyager Focus B825, B825-M and Voyager Focus UC wireless headsets. It is built to the same electrical and mechanical specifications as the factory pack. The fully decoded chip communicates with the headset exactly like the original unit. Buyers whose headset uses a different part number cannot use this battery.

360 mAh capacity restores original talk time

Rated at 360 mAh and 1.33 Wh with a nominal 7.4 V output, the cell delivers the same energy the headset was designed for. Users can expect the same listening and talk duration they had when the headset was new. The battery will not extend runtime beyond the original specification. Heavy users who need multi-day operation without recharging will find the capacity unchanged.

Compact 31.94 x 29.60 x 4.54 mm pack fits

The replacement measures 31.94 x 29.60 x 4.54 mm and weighs 7.4 g, matching the space and connector layout inside the Voyager Focus chassis. No soldering or case modification is required; the original connector plugs straight in. Installers must verify the connector orientation before closing the housing. Builders looking for a higher-capacity pack in the same footprint will not find it here.
