Our Garmin 550C has been shutting itself off after running 1

Customer Question

Our Garmin 550C has been shutting itself off after running 1 - 5 Minutes. The battery was replaced after the our first trip this year. It was properly charged and installed by an electrician. The unit is 4 - 5 years old. Any suggestions at this point?

Hi, thank you for contacting My name is Russell. I will do my best to provide the right answer to your question.

You may have a bad (new) battery.

What are the specifications of Voltage, and mAh, on the new battery?

And, you may have a defective charger. Does it seem to be charging very rapidly? then it may be defective in not charging enough before it quits, or the like, leading to an 'undercharge' of an otherwise good battery.

Was the new battery put in because the old battery also showed these symptoms of not lasting longer than a few minutes?
