It covers OEM part numbers 330107, 330107A, 359495, 359498, 330105, 330105A, 404600, and 404900. Swap it in when the original cell no longer holds charge through a full listening session.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSoundLink and SoundTouch 20 compatibility:\u003c\/strong\u003e\n    These models share the same 11.1V three-cell architecture, connector pinout, and BMS communication protocol — so one battery covers the full group without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through charge and discharge cycles on a SoundLink unit, confirmed the BMS handshake completed without fault codes, and verified the fuel gauge reported accurately across the full state-of-charge range.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge reset after install:\u003c\/strong\u003e\n    After fitting this battery, run it down to the low-battery warning before the first recharge. The SoundLink's fuel gauge calibrates on a full discharge-to-charge cycle — skipping this step causes the indicator to read full while the speaker cuts out early.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCapacity fade from constant desk-top charging on the SoundLink\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe SoundLink is frequently left on its charger between uses — topped off before it drops below 60%. Li-ion cells cycled repeatedly in the upper voltage band lose active lithium faster than cells allowed to discharge more fully. Over months, the usable capacity shrinks while the fuel gauge still reads normal. Letting the pack drop below 20% at least once a month before recharging slows this degradation and keeps the gauge accurate.\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 high volume, the SoundLink amplifier pulls current spikes that cause the battery voltage to sag below the amp's clean-power threshold while the gauge still shows charge remaining. The result is audible clipping or distortion — not a speaker fault. This happens most on aged cells but can also occur on a new battery if the fuel gauge is uncalibrated. Run one full discharge cycle after installing this battery, and the gauge will align with actual cell voltage so the speaker behaves predictably at all volume levels.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416226693210,"sku":"BWCS-BSE107SL-1","price":47.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416226725978,"sku":"BWCS-BSE107SL-2","price":55.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416226758746,"sku":"BWCS-BSE107SL-3","price":61.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BSE107SL-1.webp?v=1779761042","url":"https:\/\/batteryweb.com\/products\/bose-soundlink-replacement-battery-111v-2200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
