It fits directly into the original battery bay and connects to the same management circuit. Capacity matches the product data spec at 4.07Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGo 610 and Go Essential compatibility:\u003c\/strong\u003e\n    These models share the same battery bay dimensions (53 × 34 × 4mm), connector pinout, and 3.7V nominal voltage rail. The BMS in each unit reads cell state of charge over the same two-wire interface, so one cell covers the full list 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 charge and discharge on a Go 610 unit. The BMS accepted the cell, reported charge state accurately across the full range, and did not trigger overcurrent or overvoltage faults during testing.\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 on outdoors and let it run until it acquires a satellite fix before driving. A full power interruption clears the ephemeris data the receiver holds in memory, so the first fix after a battery swap is a cold start — expect 5 to 10 minutes outdoors versus under a minute for a warm start on a unit that has been used recently.\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 610\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Go 610's GPS receiver draws continuous power to maintain satellite tracking. When cell voltage drops toward the low threshold, the device scales back receiver sensitivity as a power-saving measure. This shows up as position drift or a reduced satellite count on the signal bar — not a hardware fault. Keeping the cell above 3.5V during navigation maintains full receiver sensitivity and stable position fix.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eGo 610 shuts off without warning before the battery indicator reaches empty\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen an aged battery is replaced with a new cell, the device's fuel gauge is still calibrated to the degraded capacity curve of the old cell. This mismatch means the on-screen indicator may show one or two bars remaining when the unit cuts out. Run two or three full charge-to-discharge cycles on the new cell so the fuel gauge recalibrates to the actual capacity. After recalibration, the low-battery warning will fire at the correct voltage — around 3.4V — giving adequate notice before shutdown.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377591156826,"sku":"BWCS-TMG610SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377591189594,"sku":"BWCS-TMG610SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377591222362,"sku":"BWCS-TMG610SL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-TMG610SL-1.webp?v=1778771747","url":"https:\/\/batteryweb.com\/products\/tomtom-go-610-replacement-battery-37v-1100mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
