Worn out batteries cause all manner of strange results. I suggest that you find out the ratio Full charge capacity divided by Design Capacity by running a Battery Report

Code:

PowerCfg /batteryreport /output D:\Desktop\BatteryReport.html /Duration 1

using the path to a convenient folder of your own in place of my D:\Desktop

The ratio Full charge capacity divided by Design Capacity tells you how much charge your battery is actually capable of storing compared to what it was designed to store. This will decrease as the battery gets used.

The Windows indicator you referred to [2%, 80%] shows instantaneous estimates of the ratio of current charge level to Full charge capacity so it could potentially show a decrepit battery as 100%.
A worn out battery might well be behaving so strangely that it completely throws that Windows indicator all over the place.

Hello @walleyeblugill,

I think changing the Battery would be a good first move, it will eliminate that as the source of the error. If nothing else, you will have a nice new Battery that should give you a few years of trouble FREE computing.

I hope this helps.
