Laptop batteries degrade over time, even with careful use. Knowing the warning signs can help you replace yours before it leaves you stranded.

1. It Drains Much Faster Than Before

If a full charge used to last you all day and now barely gets you through a few hours, that's a strong sign the battery's capacity has dropped significantly.

2. Your Laptop Shuts Down Unexpectedly

A battery reporting 20% and then suddenly dying is a classic symptom of a worn-out cell that can no longer hold an accurate charge.

3. The Laptop Only Works While Plugged In

If your device turns off the instant you unplug it, the battery may no longer be holding any usable charge at all.

4. Swelling or Bulging

A battery that looks puffy, or that's pushing your trackpad or keyboard upward, should be treated as a safety issue and replaced immediately.

5. Excessive Heat

An aging or failing battery can generate more heat than usual, even during light use.

6. Battery Health Reports

Most operating systems let you check battery health or cycle count in system settings. A significant drop in maximum capacity is a clear signal it's time for a replacement.

What to Do Next

Avoid using a swollen battery, and don't attempt to puncture or force it open. A professional technician can safely test, source, and replace the battery with a compatible part.
