I've owned my Garmin 590LM for about 5 years now, since the C14 was new.
It's a nice unit with a ton of features. It's not PERFECT, but I don't know of a better dedicated GPS unit - hence why I bought it.
After about the first year, I noticed that the battery would not seem to hold a charge, even after being in the charging cradle riding all day. Non-charging was confirmed by manually plugging into a wall charger with the same effect.
As I'm gearing up to go to the National this summer, I decided I should start looking for a new battery unit for the garmin, as it is (mostly) a proprietary unit LiOn 2000maH, small battery pack with dedicated wire harness. $50 from Revzilla.
While I strolled through various google searches on battery replacement, I came across this:

Lots of current comments on how well this works. I won't go into detail, but it's a fairly simple fix (albeit at a MICROSCOPIC level) and anyone can do it. Be warned: You WILL need a magnifying glass to see what you're doing!
Needless to say, it took me about 20 mins to dissect the tiny wire harness, and put it back together carefully.
But the result is working well, and the battery now holds a charge!
If anyone else is having this issue with their battery holding a charge when not connected to the bike or plugged into a charger, this little fix WORKS, and saved me $50.
hope this helps.
