Garmin Edge 530 Incorrect Battery % Preventing Charging

I have a Garmin Edge 530 with a really strange charging issue. The device incorrectly thinks it is always at 100% battery, which prevents it from charging. A week ago, I plugged it in at 25%, but it wouldn’t charge (tried different cables, chargers, etc.). After troubleshooting for a while, I gave up and left it unplugged and turned off overnight. The next morning, I turned it on, and it was magically at 100%, even though it had not been charging. Since then, the device constantly displays 100% and won’t charge becuse it “thinks” it’s full, but i wasn't sure at the time, i thought it might be charging and its just not displaying it. So i went on a ride with it and it died midway through.I tried plugging it in after, and it would only charge while turned off. Once it turned on by itself (bacause it charged a bit), it would stop charging again and turn of. If I force shut it down while it’s turning on (the 10 second reset method), it flashes between the dead battery icon and the charging icon in a loop. It the battery voltage sensor is faulty and giving an incorrect reading (shows roughly 98 billion in diagnostic mode and chg dsbl under it meaning "Charging Disabled"), causing the device to not charge. I''m sure if i find a way to bypass in a way the check for the battery % it will charge . The software on the Garmin is probably preventing it (correct me if i am wrong).

Update: the device will turn on if it is plugged in but once i unplug it in instantly blacks out. 


Has anyone else experienced this? I hope there is a way to fix it, i got the 540 but i would like to have it in a working state Slight smile

Any help would be appreciated!!

    Did you try performing a soft reset with a long press (about 10 sec) of the power button?

    yes i did try this many times, because i cant shut down the device normally. by holding it for 10 secs and releasing it when the garmin logo shows i can force shut it down.

    Hello Jack,

    Yes, I found the solution to my problem, I took mine to my friend’s phone repair shop and he took a look at it. He opened it up and  found out that somehow water has gotten in and there was moisture in the connectors. He cleaned it and removed all of the corrosion. Mine worked perfectly after that, but your edge it might be the battery, I was lucky and able to recover it. If your problem is exactly the same as mine when you start the device in diagnostic mode (by holding the start/stop button when powering on the device) you should see a very high number next to Vbat and underneath saying “chg dsbl”
