Compatible Replacement Battery

The Cameron Sino B0513 is a lithium-ion cell designed for the Pill 2.0 speaker and devices using part numbers MH812AMA-UG or J272/ICP092941SH. It delivers a 750mAh capacity at 7.4 volts for 5.55Wh of energy. This new battery targets owners needing a direct swap for an exhausted original pack.

Built-In Protection And Fit

The pack measures 40.66 x 30.10 x 10.10 mm and weighs 45.0g, matching the original form factor for a secure fit inside the speaker cavity. A fully decoded chip communicates with the host device exactly like the factory unit. Integrated circuitry guards against overcharge, over-discharge, over-voltage and short-circuit events to preserve cell health.

Cycle Life And Charging Limits

Lithium-ion chemistry performs best after two or three full charge and discharge cycles when new. The supplier advises against using low-quality third-party chargers, which can shorten usable life. Storage above 60°C or 140°F is not recommended, and the cell must never be disassembled or exposed to fire or water.
