5 Signs Your Laptop Battery Needs to Be Replaced (Before It Dies Completely)

Your laptop used to last for hours on a single charge, giving you the freedom to work from a coffee shop, the library, or your couch. Now, it’s constantly tethered to the wall outlet, and you’re not sure why.

Sound familiar? You’re not alone. Laptop batteries are consumable components, and like car tires, they wear out over time. Knowing the warning signs of a failing battery can save you from sudden data loss, frustration, and even a potential safety hazard.

Here are the 5 most common signs that your laptop battery needs to be replaced.

1. Your Laptop Dies Suddenly, Even When It Says There’s Charge Left

This is one of the most frustrating and telling signs. You see 30% or even 50% battery life remaining, and then without warning, your screen goes black. The laptop can no longer draw the necessary power from the battery cells, rendering the power indicator inaccurate.

This happens because the battery’s internal circuitry can no longer accurately measure the charge capacity of its degraded cells. It thinks it has power left, but the energy just isn’t there.

2. The Battery Doesn’t Last Nearly as Long as It Used To

This is the most obvious symptom, known as reduced battery life or capacity. When your laptop was new, you might have gotten 6-8 hours of use. Now, you’re lucky to get 90 minutes. All rechargeable batteries have a limited number of charge cycles. Over time, their ability to hold a full charge diminishes. If you find yourself constantly hunting for the nearest power outlet, your battery is waving a white flag.

3. Your Laptop Takes Longer to Charge Or Won’t Charge to 100%

A healthy battery should charge at a relatively consistent rate. If you notice it’s taking significantly longer to reach a full charge, or if it gets stuck at a certain percentage (like 80% or 90%) and won’t go any higher, the battery is likely failing. The cells can no longer accept or hold a complete charge, indicating they are at the end of their lifespan.

4. The Laptop Gets Physically Hot When Not Doing Much

It’s normal for a laptop to get warm during intensive tasks like gaming or video editing. However, if the bottom of your laptop, particularly the area where the battery is housed, becomes unusually hot during light use (like browsing the web or typing a document), it’s a major red flag. A failing battery has to work harder to supply power, generating excess heat that can be both a symptom and a cause of further damage.

5. You Notice a Bulge or Swelling in the Chassis

This is the most serious sign and requires immediate action.

If your laptop case seems warped, the trackpad is clicking differently, or the laptop doesn’t sit flat on a table, your battery may be swelling. This happens due to a buildup of gas from the battery’s degraded internal chemical reactions.

A swollen battery is a safety hazard and can potentially rupture or catch fire. Do not ignore this sign. Power down the laptop, unplug it, and do not use it until the battery has been professionally replaced.

Why You Shouldn’t Ignore a Failing Battery

Procrastinating on a battery replacement isn’t just an inconvenience; it carries real risks:

  • Data Loss: A sudden, unexpected shutdown can corrupt files you were working on or even damage your operating system.

  • Hardware Damage: A severely swollen battery can press against and permanently damage your laptop’s internal components, like the trackpad, keyboard, or motherboard, leading to a much costlier repair.

  • Safety Hazard: As mentioned, a swollen or overheating battery poses a fire risk.
