Battery lasts only for 2-4 months. Changed already second set in 5 months...

What could be the problem?

  • I have the same issue although my second set lasted only 2 weeks. When i replaced the batteries (with the recommended type $10!), i noticed there had been water inside.

    I used some dielectric grease on the gasket to prevent more ingress. This time, i see no moisture. 

    There are numerous complaints in the forum of water incursion. Garmin does not answer questions here. you may need to contact them for a replacement.
