It matches OEM part number BAT-00022-1050 and fits the original battery compartment at 44.13 × 35.53 × 8.77mm. Swap it in when the original cell no longer holds charge through a full round.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSG5 platform fit:\u003c\/strong\u003e\n    The SG5, SG5 Range Finder, and SkyCaddie SG5 all share the same battery bay, voltage rail, and connector orientation. One cell covers all three variants — no adapter or wiring change needed.\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. The BMS held the 3.7V nominal rail cleanly and engaged the low-voltage cutoff at the expected threshold, with no false trips during load testing at GPS-draw current levels.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eCold-start preparation after fitting:\u003c\/strong\u003e\n    After installing this cell, power the SG5 on outdoors with a clear sky view before your round. Full power removal triggers a cold GPS start — first satellite acquisition takes 5–10 minutes. Run this once at home, not on the first tee.\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 SG5\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe SG5 GPS receiver draws more current maintaining satellite lock than most users expect. As cell voltage drops toward the low-battery threshold, the unit reduces receiver sensitivity to extend remaining power. This shows up as slower distance refreshes and slight positional drift — not a satellite issue, a power issue. Keeping the cell above 3.5V prevents the sensitivity rollback from kicking in.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSG5 shuts off without warning mid-round\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eAfter fitting a new cell, the SG5's battery indicator may not be calibrated to the new cell's discharge curve. The device reads the voltage level and maps it to a fuel gauge, but that mapping drifts when a new cell is installed. The unit can hit the hardware voltage cutoff — around 3.0V — while the display still shows one bar remaining. Fix this by running two full charge-to-discharge cycles so the firmware recalibrates the low-voltage warning against the actual cell behaviour.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377718952026,"sku":"BWCS-ME600SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377718984794,"sku":"BWCS-ME600SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377719017562,"sku":"BWCS-ME600SL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ME600SL-1.webp?v=1778771880","url":"https:\/\/batteryweb.com\/products\/skygolf-sg5-replacement-battery-37v-1100mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
