It fits the same footprint as the factory cell — 64.90 × 44.10 × 5.52mm — and connects directly to the existing battery contacts. OEM part numbers PI-A05-05, LI-A1-01, LI-A05-05, and LI-A02-04 all cross to this cell.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBuddy World \/ World Color \/ DSC-GB400 fit:\u003c\/strong\u003e\n    These three models share the same battery bay dimensions, connector pinout, and 3.7V power rail. One cell covers the full group — no adapter or modification needed.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through full charge and discharge cycles on the GPS platform. The BMS responded correctly to charge termination and low-voltage cutoff — no false shutoffs and no overcharge events recorded.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst fix after battery swap:\u003c\/strong\u003e\n    After fitting this cell, power the unit on outdoors before your round and let it acquire a satellite fix. A cold start after full power removal takes 5–10 minutes for first lock. Subsequent warm starts drop to under a minute once the almanac 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 low battery on the Buddy World\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eAs cell voltage drops toward the low-voltage cutoff threshold, some Golf Buddy units reduce power to the GPS receiver module to extend operation. This shows up as slower distance updates or position drift on the course display — not a GPS signal problem, a power management response. A fresh cell holds 3.7V nominal across its discharge curve, keeping the receiver at full sensitivity. If you notice distance readings lagging or jumping, check the battery indicator first before assuming signal loss.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice shuts off without warning before the battery indicator empties\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the battery indicator is calibrated against the original factory cell's discharge curve, and a degraded or mismatched cell hits the low-voltage cutoff sooner than the indicator expects. The unit reads 30–40% remaining and cuts out anyway because actual cell voltage has already dropped to the 3.0V shutoff threshold. Fitting a new cell with a full capacity curve re-aligns real voltage with the display gauge. After the first full charge cycle, the indicator should track closely again — confirm with a full charge to 4.2V before heading out.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377634476122,"sku":"BWCS-GLF400SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377634508890,"sku":"BWCS-GLF400SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377634541658,"sku":"BWCS-GLF400SL-3","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GLF400SL-1.webp?v=1778771767","url":"https:\/\/batteryweb.com\/products\/golf-buddy-buddy-world-replacement-battery-37v-1250mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
