It restores full wireless playback when the original cell has degraded past useful capacity. Voltage and cell count match the original 4S Li-ion configuration these speakers require.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSoundLink Air, SoundDock, and 350160-1100 compatibility:\u003c\/strong\u003e\n    These three platforms share the same 14.8V nominal four-cell series arrangement, connector pinout, and BMS communication protocol — one battery serves all three without wiring or firmware conflict.\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 Air unit. The BMS handshake completed on first connect, protection circuits tripped correctly at low-cell threshold, and charge termination fired cleanly at 16.8V.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge calibration on first use:\u003c\/strong\u003e\n    After fitting this battery, run the speaker down to the low-battery warning before recharging — skipping this lets the fuel gauge start from a misaligned state-of-charge reading, which causes the indicator to show false levels for weeks.\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 top-off charging on SoundLink and SoundDock units\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThese speakers spend most of their lives sitting on a desk or shelf, plugged in and fully charged. That pattern keeps the cells at high state-of-charge for long stretches, which accelerates electrolyte oxidation on the cathode and shrinks usable capacity faster than regular cycling would. The BMS has no mechanism to force a periodic discharge when the speaker is idle. Letting the pack drop below 20% at least once a month before recharging slows that degradation and keeps the fuel gauge accurate.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eAudio distortion before the battery indicator reaches empty\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eAs the pack discharges toward its lower cutoff, cell voltage sags under the combined load of the amplifier and Bluetooth radio. The amplifier hits its minimum rail voltage before the battery indicator triggers the low-battery warning, causing clipping and audible distortion even though the display still shows charge remaining. This is a voltage sag issue, not a speaker fault. If distortion starts appearing during loud playback, check cell voltage directly — anything below 13.5V under load confirms the pack is at end of usable charge regardless of what the indicator shows.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416215584858,"sku":"BWCS-BSE350SL-1","price":114.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416215617626,"sku":"BWCS-BSE350SL-2","price":132.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416215650394,"sku":"BWCS-BSE350SL-3","price":146.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BSE350SL-1.webp?v=1779760822","url":"https:\/\/batteryweb.com\/products\/bose-350160-1100-replacement-battery-148v-1900mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
