It matches the original voltage and capacity spec and fits within the same 50 × 35 × 7mm footprint. When the original cell degrades, this swap restores the navigator to full operating capacity.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMM95242 fit:\u003c\/strong\u003e\n    The MM95242 runs a single-cell 3.7V Li-ion architecture with a compact form factor. This cell matches the connector pinout, physical dimensions, and voltage rail the device's power circuit expects. No modification needed.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell under a load profile matching the MM95242's GPS receiver and display draw. The BMS responded correctly to charge cutoff at 4.2V and discharge protection triggered at the appropriate low-voltage threshold without false trips.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eCold-start behaviour after fitting:\u003c\/strong\u003e\n    After fitting this cell, power the unit on outdoors and let it acquire a satellite fix before driving. Full power removal triggers a cold start — first fix can take 5–10 minutes outdoors. Subsequent warm starts drop to under a minute once almanac data is cached.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eGPS accuracy reduced at low battery on the MM95242\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe MM95242 steps down receiver sensitivity as voltage drops toward the low-battery threshold. At reduced sensitivity, the unit locks onto fewer satellites, which widens the position error circle. Users notice the map cursor drifting or routes recalculating unnecessarily. Keeping the cell above 3.6V under load is enough to keep the receiver running at full sensitivity.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMM95242 shuts off without warning before the battery indicator empties\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe on-screen fuel gauge on the MM95242 is calibrated to the original cell's discharge curve. A new cell — or a worn one — can cause the indicator to read inaccurately, so the device hits the hardware voltage cutoff before the visual warning fires. The fix is one full charge-discharge cycle after fitting the new cell. Run the device from 100% to automatic shutdown, then charge uninterrupted to 4.2V — the gauge recalibrates against the actual curve.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377737662554,"sku":"BWCS-MIOP360SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377737695322,"sku":"BWCS-MIOP360SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377737728090,"sku":"BWCS-MIOP360SL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MIOP360SL_1.webp?v=1778771880","url":"https:\/\/batteryweb.com\/products\/micromaxx-mm95242-replacement-battery-37v-1350mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
