Battery-Error-message

My arch linux informs me every time i restart my notebook that my battery only has about 50 % of its capacity.
Is this a message that can be trusted, can the computer really measure the capacity of a battery?
Or is there a workaround to relearn the battery?

How does it "inform you"? What tool are you using?

Moving to NC?

Re: Battery-Error-message

The way I measure the battery of my laptop is with this:

cat /sys/class/power_supply/BAT0/capacity

Which tells me how much battery is remaining. I have found this to be very accurate. If your battery refuses to charge above 50% then I would start looking into hardware problems or a bad charger connection or similar.
