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.
Other laptops reporting the same battery part number
These field reports contain an exact matching part number at the same observed voltage. That is useful evidence, but it does not guarantee the connector, dimensions, mounting points, firmware, or physical fit.

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.
