These devices rely on continuous power to maintain two-way satellite messaging and GPS navigation in areas with no cellular coverage. A failed or degraded battery cuts off that link entirely.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003einReach SE and Explorer platform:\u003c\/strong\u003e\n    These models share the same battery bay dimensions, connector pinout, and 3.7V power rail. The MYT783968 fits all four listed variants without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the inReach SE's power sequence and confirmed the BMS handshake completed correctly — the device reached full boot and acquired satellite signal without error flags.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eCold-start satellite acquisition after swap:\u003c\/strong\u003e\n    After fitting this cell, power the device on outdoors and allow it to complete a full satellite fix before heading out. Removing battery power triggers a cold start — first fix typically takes 5–10 minutes. Subsequent warm starts are 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 inReach SE\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe inReach SE's GPS receiver draws consistent power to maintain satellite lock and position accuracy. At low cell voltage — typically below 3.5V — some units reduce receiver sensitivity to protect remaining charge. This shows up as position drift or a wider accuracy radius on-screen, not a full loss of lock. Keeping the cell above 3.6V during active navigation prevents the receiver from stepping down.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003einReach SE shuts off without warning before the battery indicator hits zero\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eAfter a full battery swap, the inReach SE's fuel gauge is uncalibrated to the new cell. The device tracks charge level using learned discharge curves from the old battery, so the voltage cutoff threshold can trigger before the on-screen indicator shows empty. This causes sudden shutdowns that look like a fault. Run one full charge-to-cutoff cycle after installation — the gauge recalibrates itself and the low-battery warning returns to the correct point.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377585258586,"sku":"BWCS-DNR250SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377585291354,"sku":"BWCS-DNR250SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377585324122,"sku":"BWCS-DNR250SL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DNR250SL-1.webp?v=1778771730","url":"https:\/\/batteryweb.com\/products\/delorme-inreach-se-replacement-battery-37v-2000mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
