Replacement Battery for BeoPlay A1 2nd Gen

This Cameron Sino lithium-polymer pack replaces the original C406C2 cell inside the Bang & Olufsen BeoPlay A1 2nd Gen portable speaker. It delivers 3400mAh at 7.4V and matches the factory dimensions of 66.60 x 38.50 x 21.30mm. The unit weighs 103.0g and carries ISO9001, RoHS and CE certifications.

Installation Notes

The battery uses a fully decoded chip so the speaker recognises it immediately after the connector is seated. Many online videos demonstrate the swap, which typically involves removing a few screws and unplugging the old pack. The most common issue is a loose connector that prevents charging; press the plug firmly until it clicks. The package includes shock-absorbing foam to protect the cell during transit.

Pre-Purchase Checks

Verify that your speaker is the BeoPlay A1 2nd Gen and that the original battery bears part number C406C2. Confirm the voltage printed on the old cell reads 7.4V and the capacity is 3400mAh. Avoid using low-quality third-party chargers, as they can reduce the new pack’s lifespan. The battery reaches optimum performance after two or three full charge-discharge cycles.
