It fits the compact cylindrical housing and connects directly to the existing power management circuit. OEM part numbers 088789, 088796, 088772, and 080841 all cross-reference to this pack.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSoundLink Mini 2 fit:\u003c\/strong\u003e\n    The Mini 2 runs a single 7.4V Li-ion pack that feeds both the Class D amplifier and the Bluetooth radio. Both draws share the same cell, so a degraded pack affects audio output and wireless range at the same time — not as separate failures.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through the SoundLink Mini 2 charge circuit and confirmed the BMS handshake completed correctly. The protection board held cutoff at the expected low-voltage threshold and accepted charge from the original Bose 12V DC barrel charger without error codes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge calibration on the Mini 2:\u003c\/strong\u003e\n    After fitting a new cell, run the speaker down to auto-shutoff at least once before recharging. The SoundLink Mini 2 fuel gauge calibrates its empty reference during that first full discharge — skipping it causes the indicator to read full while the cell is already under stress.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the SoundLink Mini 2 reads full charge but shuts off during playback\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Mini 2 fuel gauge is a coulomb counter — it tracks charge in and out rather than measuring cell voltage directly. If the battery has never been fully discharged, the counter loses its zero reference and starts reporting inflated percentages. A cell that is genuinely at 15% capacity can display 60% on the indicator. Once audio demand pulls current above what the weakened cell can sustain, the protection circuit trips and the speaker cuts off. Run a full discharge cycle to ground the counter and the indicator will track correctly from that point.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eAudio distorting before the battery indicator reaches empty\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eAt higher volume settings, the Class D amplifier in the Mini 2 draws current in short sharp spikes rather than a steady load. As the cell discharges below roughly 7.0V, internal resistance rises and those spikes cause voltage to sag momentarily. The amplifier interprets that sag as a supply fault and clips the output waveform — which is heard as distortion or a crackling sound, even though the battery indicator still shows charge remaining. Reducing volume while the speaker is in that low-voltage window stops the sag and clears the distortion immediately. After a full charge cycle on the new cell, voltage holds steady through the amplifier's demand peaks and the distortion does not return.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416224956506,"sku":"BWCS-BSE796XL-1","price":51.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416224989274,"sku":"BWCS-BSE796XL-2","price":59.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416225022042,"sku":"BWCS-BSE796XL-3","price":66.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BSE796XL-1.webp?v=1779760990","url":"https:\/\/batteryweb.com\/products\/bose-soundlink-mini-2-replacement-battery-74v-3400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
