It matches OEM part numbers 010-10863-00 and 011-01451-00. Fit this when the original cell no longer holds charge through a full ride.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eZumo 400 \/ 450 \/ 500 series fit:\u003c\/strong\u003e\n    These models share an identical battery bay, connector pinout, and BMS handshake protocol across the range. One cell covers all four variants without modification.\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 the Zumo 500 platform. The BMS accepted the cell without fault codes and voltage held within the expected 3.7V nominal window under continuous navigation load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eCold-start satellite acquisition after fitting:\u003c\/strong\u003e\n    After any full power interruption, the Zumo performs a GPS cold start. Take the unit outdoors and power it on before your first ride — first satellite fix takes 5 to 10 minutes. Subsequent warm starts drop to under a minute once almanac data is cached.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSaved routes and POIs disappearing after a battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Zumo 400 and 500 series store some active navigation state and recently used data in battery-backed RAM. When you remove the old cell completely, that volatile memory loses power and clears. Saved routes stored to internal flash are usually retained, but unsaved active routes or recent destinations in RAM will not survive the swap. Before pulling the old battery, sync the device to Garmin Express or manually save any active route to internal storage.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eZumo shutting off without a low-battery warning\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eAfter fitting a new cell, the on-screen battery indicator is uncalibrated. The device's fuel-gauge reading still references the old cell's discharge curve, so the visual indicator can show two or three bars right up until the BMS hits its low-voltage cutoff threshold and shuts the unit down. This is not a fault with the replacement cell — it corrects itself after two to three full charge and discharge cycles. Run the battery down to auto-off, then charge it fully to 4.2V twice, and the indicator will track accurately.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377641226330,"sku":"BWCS-GM4XL-1","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377641259098,"sku":"BWCS-GM4XL-2","price":35.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377641291866,"sku":"BWCS-GM4XL-3","price":38.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GM4XL-1.webp?v=1778771767","url":"https:\/\/batteryweb.com\/products\/garmin-zumo-400-replacement-battery-37v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
