It fits the Zumo series and matches the OEM voltage and connector spec. The Zumo draws continuous power for GPS acquisition, map rendering, and display backlight — all from this single cell.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eZumo series fit:\u003c\/strong\u003e\n    The Zumo line shares a common battery bay geometry and a 7.4V two-cell Li-ion configuration. This replacement matches that voltage rail and uses the same connector orientation. The onboard BMS communicates with the Zumo's charge circuit 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 the Zumo's charge circuit and confirmed the BMS handshake completed correctly. The device accepted a full charge without triggering a fault state and the low-voltage cutoff fired at the expected threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eCold-start satellite acquisition after swap:\u003c\/strong\u003e\n    After fitting this battery, power the Zumo on outdoors with a clear sky view and let it run a full cold-start fix before your first ride. A power interruption clears the satellite almanac cache — first fix after a swap takes 5–10 minutes; all subsequent warm starts return to 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\"\u003eWhy the Zumo shuts off without warning near the end of a charge\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Zumo reads state-of-charge from the cell's voltage curve. After years of cycling, the original battery's curve flattens — the device reads a healthy voltage right up until the cell drops sharply. A new cell restores a normal voltage slope, but the Zumo's fuel gauge needs a full discharge-recharge cycle to recalibrate its internal threshold. Until that cycle completes, abrupt shutoffs near the bottom of the charge bar are still possible. Run one full charge and discharge outdoors to reset the calibration.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSaved routes and POIs missing after battery replacement\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Zumo stores routes, favourites, and some trip data in battery-backed memory. Removing the original battery for more than a few seconds can clear that volatile RAM. Data saved to the internal flash or an SD card survives the swap — but routes held only in active memory do not. Before pulling the old battery, export your routes to an SD card or sync to Garmin BaseCamp on a PC. Reimport after the new cell is seated and the device boots cleanly.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377557831770,"sku":"BWCS-GMZ630SL-1","price":60.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377557864538,"sku":"BWCS-GMZ630SL-2","price":71.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377557897306,"sku":"BWCS-GMZ630SL-3","price":79.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GMZ630SL-1.webp?v=1778771653","url":"https:\/\/batteryweb.com\/products\/garmin-zumo-replacement-battery-74v-920mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
