It matches OEM part numbers 080061, 080065, and 829049-0210. If your speaker no longer holds charge or powers off unexpectedly, this is the direct cell swap.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSoundlink Revolve+ 2 fit:\u003c\/strong\u003e\n    The Revolve+ 2 uses a two-cell series Li-ion pack at 7.4V nominal. The BMS inside the speaker handshakes with the pack over a dedicated data line — this battery carries the matching connector and cell configuration to pass that check without triggering a fault state.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through charge and discharge on a Revolve+ 2 unit, confirmed BMS handshake completed, verified charge acceptance from 0% to full, and checked that the speaker's onboard fuel gauge reported capacity accurately across the full discharge curve.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration after swap:\u003c\/strong\u003e\n    After fitting a new pack, run the speaker down to auto-shutoff on the first cycle before recharging fully. Skipping this step leaves the fuel gauge calibrated to the old cell's profile, which causes the battery indicator to jump or report incorrectly from day one.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Revolve+ 2 shuts off at high volume even on a charged battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eAt high volume, the amplifier pulls a sharp current spike on every bass transient. If the cell has aged, internal resistance has risen enough that these spikes cause the pack voltage to sag below the BMS cutoff threshold — even when the indicator shows 40% or more. The speaker interprets the voltage dip as a critically low cell and shuts down as a protection measure. A fresh 3400mAh pack with low internal resistance handles those transient draws without the sag, keeping voltage above the cutoff.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSpeaker shows full charge but audio starts distorting before the battery indicator reaches empty\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is amplifier clipping caused by voltage sag, not a software glitch. As a degraded cell discharges, voltage drops faster than the fuel gauge tracks — the amplifier hits its minimum supply voltage before the indicator reaches the low-battery zone. At that point the amp clips the audio waveform, producing crackling or distortion even though the display still shows bars remaining. Replacing the cell returns the discharge curve to spec and the amplifier gets clean voltage through the full cycle. Confirm the new pack is seated and the data connector is fully clicked before charging.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416179638362,"sku":"BWCS-BSE861XL-1","price":59.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416179671130,"sku":"BWCS-BSE861XL-2","price":70.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416179703898,"sku":"BWCS-BSE861XL-3","price":78.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BSE861XL-1.webp?v=1779760587","url":"https:\/\/batteryweb.com\/products\/bose-soundlink-revolve-2-replacement-battery-74v-3400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
