My Garmin Edge 530 battery had been working fine indoors, but yesterday at -16C outside, the device just turned off after about 15 minutes of use with the battery still at 60%. The device is 2 years old. I assume the issue is that the battery is not as good as it was, and now at cold temperatures the voltage is going down too low and the device turns off as a result.
Has anyone had this type of issue and found that any setting or firmware rev made any difference?
With my 2 year old 520 at cold temperatures battery life was significantly reduced, but on a full charge I would still get 5 hours of use out of it and it did not turn off until the battery hit close to zero, and with the 520 I was using it at -30C and it still worked.
The funny thing is is just recently I was thinking how good the battery in the device was...and now this.
