It matches the original part number 361-00166-00 and fits directly into the Zumo XT2 chassis. Voltage and capacity are identical to the factory spec — 3.7V, 5000mAh (18.5Wh).\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eZumo XT2 fit:\u003c\/strong\u003e\n    The XT2 uses a single flat Li-Polymer cell with a proprietary connector and integrated BMS handshake. This cell matches the original PCM layout and connector orientation, so the device powers on and reports state-of-charge correctly without throwing low-battery faults.\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 and discharge cycles on the Zumo XT2 platform. The BMS accepted the cell without error, state-of-charge reporting tracked accurately across the charge curve, and the display showed no voltage-threshold anomalies.\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 unit on outdoors in open sky and let it run until it acquires a satellite fix before mounting it on the bike. The Zumo XT2 performs a GPS cold start after any full power interruption — first fix takes 5–10 minutes versus under a minute for a warm start 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\"\u003eWhy the Zumo XT2 shuts off without warning on low battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eAfter a battery swap, the Zumo XT2's fuel gauge IC needs a full charge-to-discharge cycle to calibrate the cutoff threshold against the new cell. Until that cycle completes, the device may shut off abruptly at what the indicator shows as 20–30% remaining. The displayed percentage is an estimate based on the old cell's discharge curve — it does not reflect actual remaining charge in the new cell. Run one complete charge from 0% to 100% and back down to auto-off to reset the calibration baseline.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSaved routes missing after battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Zumo XT2 stores active trip data and recently used POIs in battery-backed volatile RAM. When the original cell is removed, that RAM loses power and the buffer clears — any unsaved routes or recent destinations will not survive the swap. Saved favourites and map data stored in flash memory are unaffected and will persist. Before removing the old battery, sync routes to Garmin BaseCamp or export them via the device's trip planner to avoid losing them.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377555570778,"sku":"BWCS-GMX200SL-1","price":39.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377555603546,"sku":"BWCS-GMX200SL-2","price":46.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377555636314,"sku":"BWCS-GMX200SL-3","price":51.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GMX200SL_1.webp?v=1778771653","url":"https:\/\/batteryweb.com\/products\/garmin-zumo-xt2-replacement-battery-37v-5000mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
