The XL2300 is a golf-course navigation device used to track distances and locate hazards on the course. At 50.81 × 34.28 × 7.81 mm, this cell matches the original footprint and connector position.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eXL2300 GPS platform fit:\u003c\/strong\u003e\n    The XL2300 uses a single-cell Li-Polymer architecture at 3.7V nominal. The onboard BMS monitors cell voltage directly — any cell outside the expected voltage window at connection triggers a low-battery flag before the unit will boot. This cell initialises within that window.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the XL2300's GPS receiver and display load. The BMS held charge termination correctly at 4.2V and cutoff activated at the expected low-voltage threshold without triggering a false fault state.\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 XL2300 on outdoors before heading to the course. A full power interruption forces a cold start — the GPS receiver has lost its last known position and almanac cache. First satellite fix can take 5–10 minutes. Subsequent warm starts lock in under a minute once the almanac is rebuilt.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eGPS accuracy dropping at low battery on the XL2300\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen cell voltage falls below roughly 3.5V, the XL2300 reduces power to the GPS receiver module to extend operation. Lower receiver sensitivity means weaker satellite signals get dropped, and position accuracy degrades — distances displayed may jump by several metres. This is firmware-level behaviour, not a hardware fault. Keep the cell above 3.6V during active navigation to maintain full receiver sensitivity.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eXL2300 shutting off without a low-battery warning\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe battery indicator on the XL2300 reads cell voltage and maps it to a percentage — but after a degraded original cell has been in use, the device's calibration point drifts. A replacement cell at full charge can hit the unit's hard voltage cutoff before the on-screen warning ever appears, because the threshold was tuned to the old cell's discharge curve. Power the XL2300 off, leave it for two minutes, then power it back on. This forces the BMS to re-read resting cell voltage and recalibrate the indicator from a stable baseline of 4.1–4.2V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377720918106,"sku":"BWCS-ME500XL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377720950874,"sku":"BWCS-ME500XL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377720983642,"sku":"BWCS-ME500XL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ME500XL-1.webp?v=1778771880","url":"https:\/\/batteryweb.com\/products\/firedoggolf-xl2300-replacement-battery-37v-1350mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
