Direct replacement for Bose SoundLink Mini 2

This lithium-ion pack matches the original 3400 mAh capacity and 7.4 V rating for the SoundLink Mini 2 speaker. It fits part numbers 088772, 088789, 088796 and 080841 so the speaker recognises the battery immediately. The decoded chip reports charge status exactly as the factory cell did. Installers can follow widely available online guides to complete the swap in minutes.

Steady output through a full listening session

The 25.16 Wh rating delivers consistent voltage across the discharge curve rather than a brief peak. Protection circuitry guards against over-charge, over-discharge, over-voltage and short circuits during extended playback. A new cell reaches its rated runtime after two or three complete charge cycles. Avoiding low-quality chargers preserves this steady behaviour over the long term.

Compact sealed pack with foam-protected shipping

The battery measures 112.55 x 37.85 x 40.70 mm and weighs 112.4 g, matching the original footprint for a snug fit inside the speaker cabinet. The connector aligns with the stock socket so no adapter or soldering is required. Each unit ships in shock-absorbing foam to prevent transit damage. Store below 60 °C and keep away from fire or water as with any lithium-ion cell.

Questions about this item

Does the 3400 mAh lithium-ion cell run hot or draw extra power during all-day playback?

The replacement pack matches the original 7.4 V, 3400 mAh specification, so heat and current draw remain the same as the factory battery during extended use.

What must I already own to install this 112.55 × 37.85 × 40.70 mm pack in my SoundLink Mini 2?

You need the speaker itself and a small screwdriver to open the battery compartment; the pack includes its own decoded chip and connector.

Will this 7.4 V, 25.16 Wh battery work correctly with the original charging circuit in my older SoundLink Mini 2?

Yes, the fully decoded chip communicates with the speaker’s existing charger just like the OEM cell, so charging behaviour is unchanged.
