回答“New battery for SkyCaddie GPS Watch?”I was able to replace my battery with battery found on ebay. 3.7V 300mAh Rechargeable Lipo Battery Pack PCM 602030 High Rate for MP3 MP4 . You must cut connect off old battery and solder on to new battery. Watch working great. My recommendation is you measure the physical dimensions of your watch battery to make sure same as this battery. Mine was, easy replacement.
