How we know

Check it yourself
On Windows, open a terminal and run powercfg /batteryreport, then open the generated HTML report — it names the battery’s model and part number. On Linux, run upower -i /org/freedesktop/UPower/devices/battery_BAT0. On any laptop, the surest method is the label printed on the battery itself, visible once you remove the back panel.
Battery health and replacement signs
Short runtime, unexpected shutdowns, or a large drop from design capacity can justify a closer check; a charging fault does not by itself prove the battery is worn out. See how to check battery health, judge replacement signs, or diagnose a charging problem.
