It uses OEM part numbers L-LB2 and 190247-1000. When the original cell loses capacity and the mouse dies faster than expected, this is the direct swap.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMX1000 and M-RAG97 fitment:\u003c\/strong\u003e\n    Both the MX1000 and M-RAG97 share the same internal battery bay, connector pinout, and 3.7V charging circuit. One cell fits both without any wiring changes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through the MX1000 charging dock and confirmed the BMS accepted the charge cycle correctly, reaching cutoff without fault flags or interrupted charging.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eCharging dock compatibility tip:\u003c\/strong\u003e\n    The MX1000 charges via its cradle, not a USB cable. If the cradle LED flashes orange and never turns green after fitting a new cell, seat the mouse firmly — the charging contacts on the underside need full surface contact to complete the circuit.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the MX1000 drains faster as the Li-ion cell ages\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells lose active lithium with each charge cycle as the electrode material degrades. The MX1000's internal charging circuit has no recalibration routine — it charges to 4.2V and stops. Once the cell's usable capacity shrinks below a threshold, the mouse shuts off well before the voltage hits the cutoff floor. Swapping the cell restores the original capacity headroom the charging circuit expects.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMouse pointer stuttering or jumping near end of charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe MX1000's 2.4GHz transmitter draws brief current spikes each time it sends a position packet. When the cell voltage sags under load — typically below 3.4V on a degraded cell — the transmitter drops packets, which shows up as stuttering or skipping on screen. This is not a USB receiver fault. Recharging fully confirms whether the cell is the cause — if stuttering stops after a full charge but returns quickly, the cell has lost capacity and needs replacement.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377933615194,"sku":"BWCS-LB2RC-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377933647962,"sku":"BWCS-LB2RC-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377933680730,"sku":"BWCS-LB2RC-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LB2RC-1.webp?v=1778773964","url":"https:\/\/batteryweb.com\/products\/logitech-mx1000-cordless-mouse-replacement-battery-37v-1800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
