It also fits models listed under part numbers 626161-0010 and 064455. Capacity is sourced from the cell spec — 3400mAh (12.58Wh).\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSoundLink Color II and Mini II compatibility:\u003c\/strong\u003e\n    Both models share the same 3.7V single-cell architecture, connector pinout, and BMS handshake protocol. One battery covers both platforms because the charge controller logic is identical across this speaker generation.\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 controller at full volume load. The BMS held charge cutoff cleanly at 4.2V and triggered low-voltage protection at the correct threshold without tripping a false shutdown during amplifier draw spikes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eMonthly discharge cycle for desk-top users:\u003c\/strong\u003e\n    If this speaker sits on a desk and gets topped off before it drops below 50%, run it down past 20% at least once a month before recharging. Constant partial charging without a full discharge causes fuel gauge drift on the onboard controller, making the battery indicator read inaccurately within a few months.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBluetooth dropping at high volume on a new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eAt peak volume, the amplifier and Bluetooth radio draw current simultaneously. If the cell's internal resistance is elevated — even on a new but poorly manufactured cell — voltage sags under that combined load. The speaker's protection circuit interprets the sag as a near-empty cell and throttles output or cuts the radio link. Check that the replacement cell holds above 3.6V under load; a healthy 3400mAh cell should not sag below that threshold during normal playback.\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\"\u003eThis happens when the cell's actual voltage drops faster than the fuel gauge expects — the amplifier hits its minimum operating voltage and clips the signal before the indicator warns you. It is common after a degraded cell is replaced with one that has been stored discharged for too long, leaving the cell in a partially recovered state. Charge the new battery to 100% before first use and let it complete a full cycle. If distortion persists below the half-charge mark, verify cell voltage directly — it should read at least 3.7V at rest when the indicator shows two bars.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416234098778,"sku":"BWCS-BSV535XL-1","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416234131546,"sku":"BWCS-BSV535XL-2","price":33.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416234164314,"sku":"BWCS-BSV535XL-3","price":36.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BSV535XL-1.webp?v=1779761042","url":"https:\/\/batteryweb.com\/products\/bose-v35-replacement-battery-37v-3400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
