It matches the OEM voltage and physical footprint at 52 x 34 x 6mm. Fit it when the original cell no longer holds a charge or causes unexpected shutdowns mid-route.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eXL and GO 60 cross-compatibility:\u003c\/strong\u003e\n    These models share the same connector pinout, cell dimensions, and 3.7V charging profile. The battery slots directly into any of the listed units without modification to the flex connector or housing.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge cycles on an XL Traffic unit and confirmed the BMS accepted a full charge without triggering overcharge cutoff. Discharge curve matched OEM spec across multiple cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst fix after installation:\u003c\/strong\u003e\n    After fitting this cell, power the GPS on outdoors before driving. The unit performs a cold start after any full power interruption — satellite acquisition on a cold start takes 5–10 minutes versus under a minute for a warm start. Do not rely on navigation until the fix is confirmed.\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 One XL Traffic\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eWhen cell voltage drops below roughly 3.5V, some TomTom XL units reduce power to the GPS receiver to extend operation. This lowers receiver sensitivity and can cause position drift or slower route recalculation. The map stays on-screen, so many users don't realise the GPS signal has degraded. Keeping the battery above this threshold — either via charging or fitting a fresh cell — restores full receiver performance.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eOne XL Traffic shuts off without warning before the battery indicator hits empty\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe on-screen battery gauge on the XL Traffic is calibrated to the original cell's discharge curve. An aged or uncalibrated replacement can hit the hardware voltage cutoff — typically around 3.2V — while the gauge still shows one bar remaining. The device cuts power abruptly to protect the cell, with no low-battery alert. After fitting this replacement, run two full charge-discharge cycles so the firmware can recalibrate the indicator to the new cell's actual discharge profile.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377742315610,"sku":"BWCS-TM800SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377742348378,"sku":"BWCS-TM800SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377742381146,"sku":"BWCS-TM800SL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-TM800SL-1.webp?v=1778771939","url":"https:\/\/batteryweb.com\/products\/tomtom-one-xl-traffic-replacement-battery-37v-1200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
