Direct replacement for Bose speakers

This 2.4 V lithium-ion pack is built to replace the original battery in Bose SoundLink 3, SoundLink 2, SoundLink II and SoundTouch 20 models. It matches the factory part numbers 330105, 330107, 359495, 359498, 404600 and 404900 so the speaker recognises it immediately. The 3400 mAh capacity restores the same runtime you had when the unit was new.

Fits inside the existing compartment

The cell measures 178.60 x 31.26 x 42.12 mm and weighs 175.6 g, matching the original footprint exactly. No case modifications, adapter cables or additional hardware are required; the pack simply slots into the speaker and connects to the stock connector. A fully decoded chip reports charge status to the speaker’s firmware without extra setup.

Steady output through long sessions

The pack delivers a constant 2.4 V across the full discharge curve, keeping volume and DSP performance stable during extended playback. Integrated protection guards against over-charge, over-discharge, over-voltage and short-circuit events so the cell remains safe under continuous load. After two or three full cycles the chemistry settles to its rated 37.74 Wh capacity.

Questions about this item

How long will the 3400mAh capacity last before it drops under continuous playback?

The pack stores 3400mAh at 2.4V (37.74Wh); runtime depends on the speaker's draw, and a new cell reaches full performance after two or three full charge cycles.

Does the 2.4V lithium-ion pack run hot or make noise during all-day use?

The battery itself is silent and produces only normal warmth; the speaker's own thermal management handles any heat generated during extended play.

Which original Bose part numbers must match for this replacement to fit?

Compatible Bose part numbers are 330105, 330105A, 330107, 330107A, 359495, 359498, 404600 and 404900; verify the number printed on your old battery before ordering.
