These are compact handheld navigation devices used for vehicle and pedestrian route guidance. Swapping the battery restores a unit that no longer holds charge or fails to power on.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGoPal E4230, E4240, E4245 compatibility:\u003c\/strong\u003e\n    All three models share the same battery bay dimensions, connector pinout, and 3.7V supply rail. The M1100 part number covers the full range — no adapter or modification needed.\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 GoPal platform. The BMS accepted charge from the device's onboard charging circuit without tripping protection cutoffs, and the unit powered up cleanly across multiple cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eCold-start satellite fix after fitting:\u003c\/strong\u003e\n    After fitting this cell, power the GPS on outdoors and let it acquire a satellite fix before driving. The navigator performs a cold start after any full power interruption — first fix typically takes 5–10 minutes. Subsequent warm starts are under a minute once the almanac 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 GoPal E4240\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe GoPal E4240's GPS receiver draws power continuously while navigating. At low battery, the device scales back receiver sensitivity to protect the remaining charge. This shows up as position drift or a signal-strength drop on screen — not a hardware fault. Keeping the battery above 30% charge during active navigation maintains full receiver performance.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eGoPal shuts off without warning before the low-battery indicator shows\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe on-screen battery gauge on the GoPal series is calibrated against the original cell's discharge curve. An aged or newly swapped cell may have a slightly different discharge profile, causing the device to hit its voltage cutoff threshold — typically around 3.0V — before the indicator reads empty. Run two full charge-to-shutoff cycles after fitting the new cell. This lets the firmware re-map the gauge to the new cell's curve and restores accurate low-battery warnings.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377650040922,"sku":"BWCS-MD420SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377650073690,"sku":"BWCS-MD420SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377650106458,"sku":"BWCS-MD420SL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MD420SL-1.webp?v=1778771802","url":"https:\/\/batteryweb.com\/products\/medion-gopal-e4240-replacement-battery-37v-1100mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
