My Detailed Initial In-Water Impressions of Garmin Mk3i

[aedwards92]

Question: has your mk2i battery life degraded substantially over time? I have an mk2i and I only charge it to ~80% because I read on the internet that charging it all the way to 100% on a regular basis will wear out the battery prematurely. Years later my battery is like new, but of course I have no idea whether that's because I don't charge it beyond 80%, or whether it would have done just as well even if I was regularly charging it to 100%. As someone who charges to 100%, what have you observed?

When I charge my Mk2i (every couple of weeks or so) I charge it to 100% and haven’t seen any degradation after 2+ years of use
