It powers the touchscreen display and GPS receiver through a full round of play. Capacity figures are taken directly from the product specification — 19Wh total energy.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSkyCaddie SX550 fit:\u003c\/strong\u003e\n    The SX550 uses a single flat Li-Polymer cell with a matching footprint of 75.20 × 57.10 × 7.00mm. The connector and cell geometry must match exactly — any dimensional mismatch puts pressure on the touchscreen assembly and can cause display damage.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the SX550's GPS-active load profile. The BMS held 3.8V nominal cleanly through sustained GPS acquisition and display-on states, with no unexpected cutoffs at the protection threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eCold-start satellite acquisition after fitting:\u003c\/strong\u003e\n    After fitting this cell, power the SX550 fully on outdoors and let it acquire a satellite fix before heading to the first tee. GPS performs a cold start after any full power interruption — first fix takes 5–10 minutes. Subsequent warm starts drop well 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 the low-battery threshold on the SX550\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen the SX550 battery drops below a certain voltage, the device can reduce GPS receiver sensitivity to protect remaining power for a clean shutdown. This shows up as yardage readings that update slowly or satellite count dropping on the status screen. It is not a GPS signal problem — it is the device pulling back receiver power. Keeping the cell above 3.6V during a round avoids this behaviour entirely.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSX550 shuts off mid-round without any low-battery warning\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA fresh replacement cell needs a full charge cycle before the SX550's battery indicator reads accurately. Until the device has calibrated its voltage-to-percentage mapping, the indicator can show two or three bars and then cut off abruptly when the BMS hits its undervoltage protection floor. Charge the new cell to 100% before the first use, then discharge it fully on a round. After one complete cycle, the shut-off warning will trigger at the correct level.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377573691482,"sku":"BWCS-SGX550SL-1","price":34.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377573724250,"sku":"BWCS-SGX550SL-2","price":39.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377573757018,"sku":"BWCS-SGX550SL-3","price":43.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SGX550SL-1.webp?v=1778771669","url":"https:\/\/batteryweb.com\/products\/skygolf-skycaddie-sx550-replacement-battery-38v-5000mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
