Garmin Battery Won't Hold a Charge?

Question

My Garmin StreetPilot c330 GPS battery no longer holds a charge. I use the mount to the dashboard, and the cord has to be plugged into the car and the unit for it to power on. It costs $150 for Garmin to repair it, which is more than I can buy one for!

So, does anyone know a trick to get it to start holding a charge again, or how to replace the battery and what type to buy?

Thanks!

Replacing the battery in these isn't hard.  You can replace it with a higher capacity battery than the original for under $20 USD.

The kink is that there are at least three different battery configurations in different strains of this model.   Disassemble your unit, read through the thread below, and identify the battery type you need before ordering a replacement.

The replacement itself isn't hard if you have any electronics skills.
