To tell if a Lenovo battery is bad, check if it loses charge quickly, fails to hold a charge, or the laptop shuts down unexpectedly. You can also use Lenovo Vantage or Windows Battery Report to check the battery's health status for warnings or a significantly reduced capacity. If the battery is swollen or the laptop doesn't recognize it, it likely needs replacing.
