These are motorcycle-mounted units that run continuously through long rides — the original cell degrades faster than a handheld GPS because of vibration, heat from the mounting position, and near-constant screen-on navigation use. Capacity is 2500mAh (9.25Wh), matching OEM spec.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eRider 400 \/ 410 \/ 550 platform:\u003c\/strong\u003e\n    All three models share the same cell housing, connector orientation, and BMS communication protocol. The VF3W part number covers the full range — voltage rail and contact pitch are identical across the lineup, so one cell fits all listed units.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles with the BMS active. The protection circuit responded correctly to over-charge and cell-temperature limits. No false cutoff events occurred during draw spikes from the GPS receiver and backlit display operating together.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eCold-start satellite acquisition after fitting:\u003c\/strong\u003e\n    After any full power interruption — including a battery swap — the Rider 400 loses its ephemeris data and performs a cold start. Take the unit outside and power it on before your ride. First satellite fix takes 5–10 minutes; warm starts after that are under a minute.\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 Rider 400\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eWhen cell voltage drops below roughly 3.5V, the Rider 400 reduces power to non-critical subsystems — and the GPS receiver sensitivity is one of them. The result is fewer satellites tracked, weaker signal lock, and occasional position jumps on the map. This is a firmware-level power-saving response, not a hardware fault. Keeping the battery above 3.6V under load maintains full receiver performance throughout a ride.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice shuts off without low-battery warning on screen\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA worn or newly fitted cell can cause the Rider 400 to cut power abruptly before the on-screen battery indicator reaches the warning threshold. The indicator is calibrated against the original cell's discharge curve — a new cell with a slightly different internal resistance reads differently under load. To recalibrate, run two full charge-discharge cycles with the unit actively navigating. After two cycles, the indicator tracks actual voltage accurately and warning appears at the correct point around 3.4V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377563697242,"sku":"BWCS-TMR410SL-1","price":40.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377563730010,"sku":"BWCS-TMR410SL-2","price":47.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377563762778,"sku":"BWCS-TMR410SL-3","price":52.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-TMR410SL-1.webp?v=1778771669","url":"https:\/\/batteryweb.com\/products\/tomtom-rider-400-replacement-battery-37v-2500mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
