Replace your battery when it no longer holds sufficient charge for your needs, shows physical damage, or the system indicates reduced capacity. Most batteries last 2-3 years with regular use.

For optimal battery life, avoid extreme temperatures (ideal range 15-25°C), don’t leave your laptop plugged in constantly, and perform occasional full discharge cycles. Store in a cool, dry place when not in use.
