My tomtom golfer2 watch is over 2 years old and for some months the battery runs empty very fast, even if I am not for golf use. If I put it then connects to the computer he is quite fast yet. If I charged watch to the computer, the battery be evicted again. Then I get the watch from there and plug it right back on. If he then again charged I use him on the golf course. He cites just 18 holes. Here is a solution for? It was however a watch of 249 euro, then you may after 2 years still expect he still functions properly.
