These handheld devices control media playback, cursor movement, and menu navigation on smart TVs, Android boxes, and PCs. Replace this cell when the remote stops holding a charge or powers off unexpectedly during use.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMini i8 and Mini i18 compatibility:\u003c\/strong\u003e\n    Both models use the same 3.7V single-cell Li-ion configuration with matching connector pinout and physical dimensions of 53.00 × 33.90 × 5.70mm — the cell slots into either unit without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran charge and discharge cycles on this cell and confirmed the protection circuit trips correctly at low-voltage cutoff and releases cleanly on recharge without requiring a manual reset.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eConnector orientation on reinstall:\u003c\/strong\u003e\n    The Mini i8 JST-style connector is not reversible by force — check that the locking tab clicks before closing the housing. A half-seated connector causes intermittent power loss that looks like a dead cell but isn't.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Mini i8 loses gyroscope tracking before the remote stops responding entirely\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe air mouse gyroscope in the i8 draws more current than basic IR functions. As the cell ages and internal resistance rises, voltage sags under gyro load even when the remote still powers on for basic button presses. You'll notice cursor drift or tracking failure while button inputs still register — that's a voltage-sag symptom, not a firmware issue. At that point the cell is below usable capacity and a swap will restore full function.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRemote registers no input at all immediately after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA fully unresponsive remote straight after fitting a new cell is almost always a connector seating issue or a cell that shipped in deep-discharge protection lockout. Check the connector tab first — it must click fully into place. If the connection is solid, plug the remote into USB charge for 10–15 minutes to let the protection circuit recover from a sub-2.5V resting state, then retest.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416101093466,"sku":"BWCS-MP162TX-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416101126234,"sku":"BWCS-MP162TX-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416101159002,"sku":"BWCS-MP162TX-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MP162TX-1.webp?v=1779760284","url":"https:\/\/batteryweb.com\/products\/rii-mini-i8-fly-air-mouse-replacement-battery-37v-1200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
