MGI did everything I could expect to replace my battery charger. However I had to visit a couple of different golf shops to determine the problem with my battery not being charged was not the battery but the charger. The first two golf shops didn't have a compatible charger to prove my battery would charge. The third one did and that one charged my battery, so there was no doubt my problem was the charger. How often do such chargers fail? Is there a common fault? Do you want my failed charger to determine why it won't charge? I am surprised that it cost over $140 to replace.
