The OEM part number is 626161-1040. Over time, the stock cell loses charge capacity and causes the speaker to cut out early or fail to power on from a full-charge indicator.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSoundLink Color II fit:\u003c\/strong\u003e\n    The 08319 uses a single-cell 3.6V pack with a specific connector orientation and BMS handshake tied to the speaker's charge controller. This cell matches that voltage rail and physical footprint — 67.70 × 17.50 × 22.00mm — so the charge IC recognises it without error flags.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the SoundLink Color II charge circuit and confirmed the BMS negotiated cleanly with the speaker's onboard charge controller. Charge termination triggered at the correct cutoff voltage with no fault codes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eMonthly discharge cycle for the SoundLink Color II:\u003c\/strong\u003e\n    This speaker sits on desks and gets topped off constantly. That shallow cycling causes fuel gauge drift — the charge indicator reads full while actual capacity is 60% or less. Let the speaker run down below 20% at least once a month before plugging it back in.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eAudio distorting before the battery indicator reaches empty on the SoundLink Color II\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eWhen a degraded or deeply cycled cell loses its ability to hold voltage under load, the amplifier inside the SoundLink Color II clips before the battery indicator shows low. The amp draws a short burst of higher current at louder volumes, and an aged cell's internal resistance causes the voltage to sag below what the amplifier needs — the result is distortion, not silence. This happens because the speaker's indicator reads resting voltage, not loaded voltage. Replacing the cell removes the sag; on a fresh 2600mAh cell, loaded voltage stays stable across the amp's operating range.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSoundLink Color II not waking from USB charge after sitting discharged for weeks\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eA deeply discharged Li-ion cell drops below the minimum voltage USB charge controllers will accept — typically under 2.5V — and the speaker appears completely dead when plugged in. The BMS blocks charging to protect the cell, but that also means the charge LED shows nothing and the speaker won't respond. Some units will recover if left on a low-current charger for 15–30 minutes, which allows the cell to trickle up past the BMS acceptance threshold. If the cell has been in deep discharge for an extended period and won't recover past 2.8V, replacement is the only path forward.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416189632602,"sku":"BWCS-BSE319SL-1","price":36.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416189665370,"sku":"BWCS-BSE319SL-2","price":42.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416189698138,"sku":"BWCS-BSE319SL-3","price":47.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BSE319SL-1.webp?v=1779760725","url":"https:\/\/batteryweb.com\/products\/bose-08319-replacement-battery-36v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
