Replacement battery for BOSE speakers

This Cameron Sino lithium-ion cell replaces the original pack in BOSE 520II, 525II, 535, 535II, T20 and V35 models. It delivers 3400mAh at 3.7V and matches the factory dimensions of 66.10 x 21.74 x 18.60 mm. A fully decoded chip ensures the speaker recognises the battery exactly like the original unit. Buyers needing a different form factor or voltage cannot use this pack.

Fits directly into the speaker chassis

The battery slides into the existing compartment without adapters or soldering. Its 50.0g weight keeps the speaker balance unchanged. No external charger is required; the speaker’s own circuitry manages charging through the standard connector. Installers should verify the part number 064454 or 626161-0010 on the old cell before fitting. Builders looking for a higher-capacity upgrade will not find it here.

Protective packaging and decoded chip

The shipment includes shock-absorbing foam that guards the cell during transit. The onboard protection circuit guards against overcharge, over-discharge, over-voltage and short circuits. A new battery reaches peak runtime after two or three full charge cycles. Users relying on third-party chargers not approved by BOSE may see reduced service life.
