Replacement Battery for BOSE SoundLink Speakers

This 11.1V lithium pack replaces the original battery in BOSE Sound 20, SoundLink II, SoundLink 3 and SoundLink 2 systems. It delivers a rated 3000mAh capacity for extended portable listening. The unit is built to the same electrical specifications as the factory cell. It suits owners who need a direct swap for a depleted or failing internal battery.

Installation Notes and Common Issues

The pack fits inside the speaker’s existing battery compartment using the original connector. No soldering or tools beyond a small screwdriver are typically required. The most frequent issue is ordering the wrong part number; verify the code printed on your old cell before purchasing. Improper alignment of the connector can prevent the speaker from powering on.

Compatibility Check Before Ordering

Confirm that your speaker model appears in the supported list: Sound 20, SoundLink II, SoundLink 3 or SoundLink 2. Cross-reference the part number on your current battery against 359495, 330105A, 359498, 330107A, 404900, 404600, 330107 or 330105. This pack is not suitable for other BOSE portable speakers or for devices that require a different voltage or form factor.

Questions about this item

How can I confirm the replacement battery is working correctly after installing it in my SoundLink 3?

The speaker should power on and show a full charge indicator; the 11.1V lithium pack rated at 3000mAh or 3400mAh should deliver normal playback time without unexpected shutdowns.

What comes in the box and do I need any extra parts to fit this battery?

The package contains one 11.1V lithium battery pack measuring 178.6 x 31.26 x 42.12mm and weighing 355.6g; no additional components are required for installation.

Which capacity version should I choose for my SoundLink 2 — the 3000mAh or 3400mAh listing?

Both figures describe the same 11.1V replacement pack (37.74Wh); select the single 1-pack option that matches your original part number such as 330105, 330107, 359495 or 359498.
