Replacement battery for BOSE SoundWear Companion

This replacement battery fits the BOSE SoundWear Companion speaker and delivers 1000 milliamp hours at 3.7 volts. It matches the original AHS803040 part number and uses lithium-ion chemistry with a fully decoded chip that works like the factory cell.

Fits the speaker without extra hardware

The cell measures 41.50 by 30.00 by 8.00 millimetres and weighs 18.4 grams, so it slides into the existing battery compartment. No adapter cables or firmware updates are required, and the built-in protection circuit guards against overcharge, over-discharge, over-voltage and short circuits.

Suits owners needing a direct cell swap

Ideal for users whose SoundWear Companion no longer holds a charge and who are comfortable opening the device. Not for buyers who want a higher-capacity pack, a different voltage, or a battery for another speaker model.

Questions about this item

How long does the 1000 mAh capacity last before the speaker needs recharging?

Runtime depends on the speaker's power draw; the cell stores 3.70 Wh so actual hours vary with volume level and usage pattern.

Does the battery become hot or noisy during extended playback?

The lithium-ion pack has no moving parts and includes over-temperature protection, so it runs silently and stays within safe thermal limits under normal load.

Must the original BOSE connector and mounting frame be reused for installation?

Yes, the replacement cell matches the 41.50 x 30.00 x 8.00 mm form factor and uses the same connector, so the existing hardware is retained.
