It fits both the standard P4225 and the P4225 M5 variant. Capacity matches the OEM specification at 4.07Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGoPal P4425 and P4225 series fit:\u003c\/strong\u003e\n    These models share the same battery bay dimensions, connector pinout, and 3.7V single-cell charging circuit. One cell covers both navigation units without any modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through full charge cycles on the GoPal P4425 and confirmed the BMS accepted charge without triggering overcharge protection. Voltage at full charge measured 4.18V — within the 4.20V ceiling the device controller expects.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst power-on after fitting:\u003c\/strong\u003e\n    After fitting this cell, power the unit on outdoors and let it acquire a satellite fix before driving. A cold start after full power removal takes 5–10 minutes for first lock. Subsequent warm starts drop back 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 P4425\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen cell voltage drops below roughly 3.5V, the GoPal P4425 reduces power to the GPS receiver to extend operation. Lower receiver sensitivity means the unit holds fewer satellites and position accuracy degrades — sometimes by 10–20 metres. You may notice the blue dot on-screen drifting or snapping to road incorrectly. Fitting a fresh cell and charging to full restores the receiver to full sensitivity immediately.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eGoPal P4425 shutting off without low-battery warning\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eAn aged or deeply discharged cell loses the flat mid-discharge voltage plateau that the device uses to estimate remaining charge. The on-screen indicator reads three bars, then the unit cuts off — no warning shown. This happens because the voltage drops sharply below the shutdown threshold before the indicator recalibrates. Run two full charge-and-discharge cycles after fitting the new cell to let the fuel gauge re-anchor its reference points.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377633886298,"sku":"BWCS-MD425SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377633919066,"sku":"BWCS-MD425SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377633951834,"sku":"BWCS-MD425SL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MD425SL-1.webp?v=1778771767","url":"https:\/\/batteryweb.com\/products\/medion-gopal-p4425-replacement-battery-37v-1100mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
