Needs to be replaced every few months as the pins wear out or become damaged. If it was from sweat or other contaminants, one would think the pins on the back of the watch would have the same problem. You are not. Replacing the charger always solves the problem; never had any problems with the watch. Garmin should do something to improve the charger so I don't have to spend $15 on a new charger every few months. The cost of chargers will soon be the same as all watches.
