Both devices use the same L-LY11 cell format, matched by voltage rail and connector pinout. Capacity figures are taken directly from product data — 2.22Wh total energy.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMX Revolution and G930 shared cell:\u003c\/strong\u003e\n    Logitech used the same 3.7V Li-ion cell across the MX Revolution mouse and G930 headset because both run low-current radios from a single-cell pack. The BMS handshake, connector pitch, and physical footprint (43.15 × 37.56 × 7.50mm) are identical across both platforms.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on the MX Revolution. The BMS held termination voltage at 4.2V charge and tripped low-voltage cutoff cleanly at 3.0V — no false trips at rest or under RF polling load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eMX Revolution charging protocol:\u003c\/strong\u003e\n    The MX Revolution charges through its docking cradle, not a USB cable. Dock the mouse fully after replacing the battery so the cradle's charging circuit can complete an initial full cycle — partial cradle contact causes the charge LED to flash without delivering current.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the MX Revolution stops reconnecting after a battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe MX Revolution's USB receiver stores a pairing key in volatile memory that clears when the battery drops below the BMS cutoff threshold. A full power loss — which happens during a cell swap — can wipe that handshake. The mouse and receiver then both sit idle waiting for the other to initiate. Unplug the USB receiver, wait ten seconds, replug it, then press the Connect button on the underside of the mouse to force a fresh pairing cycle.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMouse pointer stuttering or skipping after new battery installed\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eStuttering immediately after a cell swap usually means the new battery hasn't reached operating voltage yet — the BMS may be in soft-start mode. The 2.4GHz radio polling rate also throttles down when the cell sits below roughly 3.5V, causing visible cursor lag that looks like a tracking fault. Leave the mouse docked for a full charge cycle before testing pointer performance. If stuttering continues at full charge, check that the USB receiver isn't sharing a hub with high-current USB devices pulling voltage away from the port.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377934172250,"sku":"BWCS-LOY11RC-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377934205018,"sku":"BWCS-LOY11RC-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377934237786,"sku":"BWCS-LOY11RC-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LOY11RC-1.webp?v=1778773965","url":"https:\/\/batteryweb.com\/products\/logitech-mx-revolution-replacement-battery-37v-600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
