It fits the R600 directly — same connector, same form factor, same voltage rail. Capacity figure is 2600mAh (9.62Wh), taken from the product data, not estimated.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eR600 platform fit:\u003c\/strong\u003e\n    The R600 uses a single-cell 3.7V Li-ion pack with a dedicated BMS that monitors cell voltage and temperature. This replacement matches that voltage rail and connector pinout so the BMS handshake completes correctly on first boot.\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 bench with the BMS active. The protection circuit tripped at the correct low-voltage cutoff and the charge controller accepted a full charge cycle without fault flags.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eCold-start satellite acquisition after power interruption:\u003c\/strong\u003e\n    After fitting this battery, power the R600 on outdoors and let it run until it acquires a satellite fix before driving. A full cold start — which occurs any time the unit loses all power — takes 5–10 minutes for first fix. Subsequent warm starts return to under a minute once ephemeris 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\"\u003eGPS accuracy reduced at low battery on the R600\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSome GPS units, including portable navigators in this class, throttle receiver sensitivity as cell voltage drops toward the cutoff threshold. On the R600, this can show up as position drift or a weaker satellite signal count before the unit shuts off. The receiver draws significant current during active navigation, and a weakened or aged cell sags in voltage under that load. Replacing the cell with a fresh 3.7V unit at full charge restores the receiver to full operating voltage.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eR600 shuts off without warning during navigation\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the battery indicator is no longer calibrated to the actual cell capacity — the unit shows bars remaining but the cell voltage has already dropped below the BMS cutoff. It is common with aged or partially degraded Li-ion cells whose voltage curve no longer matches what the firmware expects. The fix is a full charge cycle on the new cell, then a complete discharge under normal navigation use so the firmware re-learns the voltage-to-capacity curve. After one full cycle, the low-battery warning should appear at the correct threshold before shutdown.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377622286426,"sku":"BWCS-AUR600XL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377622319194,"sku":"BWCS-AUR600XL-2","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377622351962,"sku":"BWCS-AUR600XL-3","price":33.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AUR600XL-1.webp?v=1778771731","url":"https:\/\/batteryweb.com\/products\/asus-r600-replacement-battery-37v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
