It fits units using OEM part numbers PI-A05-05, LI-A1-01, LI-A05-05, and LI-A02-04. Same voltage, same capacity, same connector as the factory cell.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eWorld, World Color, and DSC-GB400 compatibility:\u003c\/strong\u003e\n    These three Golf Buddy models share the same battery bay dimensions (64.90 × 44.10 × 5.52 mm), voltage rail, and connector pinout. The BMS on each unit accepts this cell without requiring firmware intervention or re-pairing.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on a DSC-GB400 unit. The BMS accepted the cell immediately, charge termination triggered correctly at 4.2V, and the low-battery indicator fired at the expected 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 device on outdoors and let it acquire a satellite fix before heading to the first tee. GPS units perform a cold start after full power removal — first fix takes 5–10 minutes. Subsequent warm starts run under a minute.\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 Golf Buddy World\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen cell voltage drops below roughly 3.5V, some Golf Buddy units reduce receiver sensitivity to protect remaining charge. This cuts the number of satellites tracked and widens the position error — distances to the pin can drift by several yards. The fix is straightforward: a fresh or fully charged cell keeps the receiver running at full sensitivity for the entire round. If you notice yardage figures becoming erratic late in a round, low voltage is the first thing to check.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice shuts off without a low-battery warning\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the battery indicator is uncalibrated to the cell's actual discharge curve. The fuel gauge reads a safe level while the cell voltage has already dropped to the BMS cutoff threshold — typically 3.0V on these units — so the device powers off with no visual warning. Running two full charge-discharge cycles after fitting the new cell lets the BMS re-learn the discharge curve. After that, the low-battery alert fires at the correct point rather than at shutdown.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377592500314,"sku":"BWCS-GLF400XL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377592533082,"sku":"BWCS-GLF400XL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377592565850,"sku":"BWCS-GLF400XL-3","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GLF400XL-1.webp?v=1778771730","url":"https:\/\/batteryweb.com\/products\/golf-buddy-world-replacement-battery-37v-1700mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
