Garmin 305 Battery Replacement

My 4 year old Garmin 305 was becoming nearly unuseable because the battery would not hold a charge for more than an hour.

I called Garmin, and they offered a refurbished 305 for $99, or a $99 credit toward a new model.

I was deciding what to do when I stumbled upon this:

I bought the ipod mini battery and did the replacement, and I now get about 10 hours on a charge.

If you have an older Garmin, you may want to give it a shot...
