Problems with calibrate battery to display correctly percentage on Linux Lite

[arliccio]

Hi there !

I bought a new battery shell to my old laptop. At the very hour of the purchase, I did the tip of charge it for 8 hours. Eventually the machine begun to suddenly shut down, even when the battery displayed 40% before the power off.

I already tried several times to drain the battery to zero and then charge it to 100% ― another tip I read at the forums.

Someone knows what can I do at the specific Linux Lite situation for calibrate my battery?

BTW, my battery features through "upower -i /org/freedesktop/UPower/devices/battery_BAT0" is the following:
