It matches the original form factor at 52.00 × 35.50 × 11.20mm, fitting the battery bay without modification. Voltage and capacity are identical to factory spec.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eZumo 590 \/ 590LM \/ 595 platform fit:\u003c\/strong\u003e\n    These three units share the same battery bay geometry, connector pinout, and BMS communication protocol. The Zumo line uses a single-cell Li-ion pack with integrated thermistor — this cell carries the matching thermistor so the device's charge controller reads temperature correctly and won't abort mid-charge.\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 on a Zumo 590. The BMS accepted the cell without fault flags, charge termination triggered correctly at full capacity, and the low-voltage cutoff fired at the expected threshold — no premature shutdowns during discharge.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eCold-start GPS initialisation after fitting:\u003c\/strong\u003e\n    After fitting this cell, power the Zumo fully on outdoors before mounting it on the bike. The GPS module performs a cold start after any full power interruption — expect 5–10 minutes for the first satellite fix. 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\"\u003eWhy the Zumo 590 shuts off without warning before the battery indicator hits zero\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Zumo 590's fuel gauge is a voltage-based estimator calibrated to the original cell's discharge curve. A new or aged cell with a slightly different curve means the device reads remaining capacity inaccurately. When the actual cell voltage drops below the hardware cutoff threshold, the unit powers off — even if the on-screen indicator showed 20% remaining. To recalibrate, run two full discharge-to-shutoff cycles followed by complete charges. After those cycles, the estimator tracks the new cell's curve and warning behaviour returns to normal.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSaved routes and waypoints missing after battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Zumo 590 stores maps and most route data on internal flash, which is non-volatile and survives a full power removal. However, active trip logs, current route state, and some user waypoints held in battery-backed SRAM are lost the moment voltage drops to zero during a swap. Before removing the old battery, sync the device to Garmin Express or export waypoints via the unit's built-in export function. After fitting this cell and powering on, re-import the exported file — waypoints restore fully and the device resumes normal operation.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377588076634,"sku":"BWCS-GMZ590SL-1","price":32.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377588109402,"sku":"BWCS-GMZ590SL-2","price":37.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377588142170,"sku":"BWCS-GMZ590SL-3","price":41.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GMZ590SL-1.webp?v=1778771731","url":"https:\/\/batteryweb.com\/products\/garmin-010-01603-10-replacement-battery-37v-1800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
