The Pro 8000 is a commercial-grade portable navigator used in fleet and logistics operations. When the original cell degrades, this replacement restores the device to working order without a full unit replacement.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTomTom Pro 8000 fitment:\u003c\/strong\u003e\n    This cell matches the voltage rail, physical dimensions (62 × 37 × 5mm), and connector orientation of the Pro 8000 mainboard. The BMS in these navigators communicates charge state to the display — this cell's protection circuit responds correctly to that handshake.\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 and monitored BMS cutoff behaviour under simulated GPS receiver and display loads. The protection circuit held stable across charge thresholds without false trips.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-fix cold start after installation:\u003c\/strong\u003e\n    After fitting this cell, power the unit on outdoors before driving. The Pro 8000 performs a cold start after any full power interruption — first satellite acquisition can take 5–10 minutes. Subsequent warm starts resolve in 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 dropping at low battery on the Pro 8000\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Pro 8000 reduces RF receiver sensitivity when battery voltage falls below a threshold — this cuts power draw but degrades position accuracy. You may notice the route line drifting or the device losing lock in areas that normally work fine. This is not a software fault. Keeping the cell charged above 3.5V prevents the receiver from entering low-power sensitivity mode.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePro 8000 shutting off without a low-battery warning\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eAfter fitting a new cell, the fuel gauge IC needs a full charge-discharge cycle to recalibrate its voltage-to-percentage mapping. Until that cycle completes, the device can hit its actual cutoff voltage before the on-screen indicator shows a warning. Charge the unit to 100%, use it on active navigation until it shuts off naturally, then charge again fully — one cycle is enough to recalibrate the threshold.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377657282650,"sku":"BWCS-TMP800SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377657315418,"sku":"BWCS-TMP800SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377657348186,"sku":"BWCS-TMP800SL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-TMP800SL-1.webp?v=1778771819","url":"https:\/\/batteryweb.com\/products\/tomtom-pro-8000-replacement-battery-37v-1250mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
