You can tell if your Lenovo battery is bad if it drains unusually fast, doesn't charge fully, or your laptop shuts down unexpectedly even when the battery shows a charge. You can also check the battery health in Lenovo Vantage or BIOS; if it reports the battery as "poor" or "needs replacement," it's likely time for a new battery.
