It fits the keyboard and mouse units that use OEM part number 190264-0000, also cross-referenced as L-LC3H-AA. When the original battery loses charge capacity, swapping this in restores full wireless operation across both peripherals.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eLX 700 keyboard and mouse compatibility:\u003c\/strong\u003e\n    The LX 700 system — including the M-BAK89B mouse — shares a common 2.4V Ni-MH cell format across both units. The same voltage rail and physical footprint means one battery type covers the entire desktop combo without adapter modifications.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on the LX 700 platform. The battery accepted a full charge without thermal flags, and voltage output held steady across keyboard polling and mouse tracking loads.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eReplace both cells at the same time:\u003c\/strong\u003e\n    If your LX 700 uses a dual-cell configuration, swap both simultaneously even if only one reads low. Mismatched cells — different ages or charge states — cause the fresher cell to drain disproportionately fast as it compensates for the weaker one.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eKeyboard pairing lost after battery swap on the LX 700\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eRemoving the battery causes a full power loss to the keyboard's onboard memory. On the LX 700, this can clear the stored pairing state with the USB receiver. The fix is straightforward: plug the USB receiver into a direct port (not a hub), then hold the Connect button on the keyboard for three seconds until the receiver LED flashes. Voltage from the new cell needs to stabilise above 2.2V before the handshake completes reliably.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMouse pointer stuttering or cutting out on the LX 700\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eStuttering or intermittent dropout from the M-BAK89B mouse is a recognised end-of-life symptom — not a receiver fault. As cell voltage drops below usable threshold, the 2.4GHz polling rate from the mouse to the USB receiver becomes inconsistent, which the OS reads as cursor lag or freezing. Replacing the battery and confirming it charges to at least 2.4V output resolves this in most cases. If stuttering persists after a fresh charge, replug the USB receiver to force a clean channel negotiation.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377934860378,"sku":"BWCS-LOX7RC-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377934893146,"sku":"BWCS-LOX7RC-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377934925914,"sku":"BWCS-LOX7RC-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LOX7RC-1.webp?v=1778773964","url":"https:\/\/batteryweb.com\/products\/logitech-lx-700-cordless-desktop-replacement-battery-24v-1800mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
