It fits the handheld unit directly and matches the original connector and BMS communication profile. Capacity is 1050mAh (3.89Wh) — identical to the factory specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eXL2300 platform fit:\u003c\/strong\u003e\n    The XL2300 uses a single-cell 3.7V Li-ion pack with a specific connector keyed to this form factor. The BMS in the rangefinder monitors cell voltage and temperature directly — a mismatched cell triggers a charge-refusal fault. This cell handshakes correctly with that BMS.\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 XL2300 platform. The BMS accepted the cell without fault codes, balanced correctly at 4.2V full charge, and the low-battery cutoff triggered at the expected 3.0V floor with no premature shutoffs.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eCold-start satellite acquisition after installation:\u003c\/strong\u003e\n    After fitting this cell, power the XL2300 on outdoors with a clear view of the sky and let it run through a full satellite acquisition before use. GPS units perform a cold start after any complete power interruption — first fix can take 5–10 minutes, but subsequent warm starts drop to under a minute once the almanac 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 XL2300\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eAs the XL2300 cell voltage drops toward 3.2–3.3V, the unit reduces power to the GPS receiver module to extend operating time. That power reduction lowers receiver sensitivity, which means the unit may drop to fewer satellites or shift to weaker signals. Distance readings can drift by several yards when this happens. Keep the cell charged above the halfway indicator to maintain full receiver sensitivity during a round.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eXL2300 shuts off without warning before the low-battery indicator appears\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe low-battery indicator on the XL2300 is calibrated against the original cell's discharge curve. A new cell — or a degraded one — can have a slightly different voltage-to-capacity curve, causing the unit to hit the hardware cutoff voltage before the software warning has triggered. This is not a fault with the replacement cell. Recalibrate by running two full charge-discharge cycles so the BMS can re-map the cutoff threshold to the new cell's curve.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377721475162,"sku":"BWCS-ME500SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377721507930,"sku":"BWCS-ME500SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377721540698,"sku":"BWCS-ME500SL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ME500SL-1.webp?v=1778771880","url":"https:\/\/batteryweb.com\/products\/firedoggolf-xl2300-replacement-battery-37v-1050mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
