About this replacement
SkyCaddie Golf LINX — 3.7V Li-Polymer Replacement Battery (CP-SCGL)
This 3.7V, 200mAh lithium-polymer cell replaces the original battery in the SkyCaddie Golf LINX GPS smartwatch. The Golf LINX is a wrist-worn golf GPS device that shows course maps, hole distances, and shot tracking data. Cell capacity drops after repeated charge cycles — swapping the battery restores normal multi-day performance.
- Golf LINX platform fit: The CP-SCGL cell is the only cell that fits the Golf LINX housing. The connector pinout and BMS handshake are specific to this watch platform. Using a generic cell with a different connector will break the fuel gauge communication and the watch will report incorrect charge levels.
- Bench tested on actual hardware: We ran this cell through full charge and discharge cycles on the Golf LINX platform. The BMS accepted the new cell without error flags, fuel gauge registration completed after one full charge cycle, and GPS acquisition functioned normally throughout testing.
- Post-swap charge cycle on the Golf LINX: After fitting this cell, place the watch on its magnetic charger immediately and charge to 100% before first use. The fuel gauge IC on the Golf LINX platform loses its charge reference when the old cell is removed. Without a full charge cycle from near-zero, the watch will display inaccurate battery percentages for days.
Why the Golf LINX GPS drains this new cell faster than expected in the first week
A new lithium-polymer cell has a slightly different internal impedance profile compared to the aged cell it replaces. The Golf LINX GPS and BLE radios draw current based on the impedance they measure at startup, and the first several charge cycles recalibrate that draw. Expect drain to appear heavier than normal for the first five to seven days. After three to four full charge cycles, the fuel gauge IC settles on the correct current profile and reported battery life stabilises.
Golf LINX not pairing to the app after battery replacement
Removing the battery cuts power to the BLE stack and the active pairing session is lost. The phone retains the old device record but the watch no longer recognises it. Go into your phone's Bluetooth settings, forget the Golf LINX device entry, then re-pair from scratch through the SkyCaddie app. The watch must be powered on and showing the home screen before the app can see it during the pairing scan.
