It fits the portable sat-nav's original battery bay without modification. Capacity is 1100mAh — matching the factory specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGo 750 and 740 Live compatibility:\u003c\/strong\u003e\n    These models share the same 3.7V battery bay, connector pinout, and charge-management circuit. The Go 750 Live variant uses identical hardware — there is no separate cell for the Live-enabled unit.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through full charge and discharge on a Go 750 unit. The onboard charge controller accepted the cell immediately, BMS communication was clean, and the device reached a full charge state without fault 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 GPS fully on outdoors before driving. The device performs a cold start after any complete power interruption — first satellite fix takes 5–10 minutes. Subsequent warm starts lock in under a minute. Do not judge the battery or receiver by first-fix performance immediately post-swap.\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 Go 750\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eAs the Go 750's cell voltage drops toward the lower threshold, the device reduces power to the GPS receiver module to extend operation. This cuts receiver sensitivity — the unit may drop to fewer satellites or show position drift that wasn't present at full charge. If navigation accuracy degrades noticeably mid-route, check the battery indicator first. A fresh cell running at 3.7V nominal restores full receiver power and position accuracy.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eGo 750 shutting off without warning before the indicator shows empty\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Go 750 calibrates its battery gauge against the original cell's discharge curve. A new cell may trigger the BMS low-voltage cutoff before the onscreen indicator visually reaches empty — the gauge is reading incorrectly, not the battery. Run two or three full charge-to-cutoff cycles and the gauge recalibrates to the new cell's actual curve. After recalibration, the low-battery warning appears at the correct threshold near 3.4V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377673076826,"sku":"BWCS-TM750SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377673109594,"sku":"BWCS-TM750SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377673142362,"sku":"BWCS-TM750SL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-TM750SL-1.webp?v=1778771819","url":"https:\/\/batteryweb.com\/products\/tomtom-go-750-replacement-battery-37v-1100mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
