It restores portability to a GPS unit that no longer holds a useful charge. Voltage and capacity match the original cell exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGo 300–530 series compatibility:\u003c\/strong\u003e\n    These models share the same VF5 battery format, voltage rail, and connector layout. The BMS handshake across the range accepts this cell without error flags or charge faults.\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 500 unit. The BMS accepted the cell cleanly, reached full charge without thermal event, and held voltage through a full navigation session without sag cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst satellite fix after swap:\u003c\/strong\u003e\n    After fitting this cell, power the unit on outdoors and let it run a cold-start acquisition. Full power removal clears the GPS receiver's almanac data, so the first fix can take 5–10 minutes. Subsequent warm starts drop back under a minute once almanac data rebuilds.\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 when the battery runs low\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSome TomTom Go units reduce RF receiver sensitivity at low state-of-charge to conserve power. When this kicks in, the unit may show a weaker satellite signal count or drift position slightly on the map. This is a firmware-level power saving decision, not a fault with the cell itself. Keeping the battery above 3.5V per cell under load prevents the unit from entering this reduced-sensitivity mode.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice shuts off without warning before the low-battery indicator appears\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the battery gauge software is uncalibrated after a cell swap — the unit's fuel gauge still references voltage curves from the old, degraded cell. The shutdown voltage threshold gets hit before the on-screen indicator has time to show a meaningful warning. To recalibrate, run the unit on active navigation from a full charge down to auto-shutoff once, then charge fully without interruption. After one full cycle, the gauge maps correctly to the new cell's discharge curve.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377601118298,"sku":"BWCS-TM300HL-1","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377601151066,"sku":"BWCS-TM300HL-2","price":32.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377601183834,"sku":"BWCS-TM300HL-3","price":35.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-TM300HL-1.webp?v=1778771747","url":"https:\/\/batteryweb.com\/products\/tomtom-go-300-replacement-battery-37v-3000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
