A laptop battery is one of the most vital components of your device, allowing you to work or study on the go without being tied to a charger. Over time, however, batteries naturally lose their ability to hold a charge effectively. Knowing when to replace your laptop battery can save you from unexpected shutdowns and performance issues. Here’s how to spot the signs that your laptop might need a new battery.
1. Your Laptop Drains Power Quickly
If your laptop can no longer hold a charge for long periods, even after being fully charged, it’s a clear indication that the battery is degrading. A healthy battery should last several hours under moderate use. When it drops to less than an hour of runtime or shuts down suddenly, it’s likely time for a replacement.
2. The Battery Warning Icon Appears Frequently
Most laptops will display a “consider replacing your battery” or “plugged in, not charging” notification when the battery’s health drops below a certain threshold. This is your system’s built-in way of telling you that performance is declining and the battery should be serviced soon.
3. Your Laptop Feels Hot or Swells Up
An overheating battery or a bulge under the trackpad or keyboard can be dangerous. Heat and swelling often indicate internal chemical breakdown, which can lead to leaks or short circuits. If you notice these symptoms, stop using the device immediately and consult a professional repair service in Durban, such as Matnet, for safe replacement.
4. The Laptop Only Works When Plugged In
When a laptop shuts off instantly after being unplugged, even if the battery appears to be charged, that’s a strong sign it’s no longer holding any power. This means the battery is effectively dead and must be replaced to restore portability.
5. The Charging Time Is Unusually Long
If your battery takes far longer than usual to reach a full charge, it may be wearing out internally. As batteries age, their efficiency decreases, forcing the laptop to work harder to maintain a charge. Over time, this also puts stress on your power adapter.
6. Battery Health Reports Show Poor Performance
Many modern laptops, including Windows and macOS devices, allow you to generate a battery health report. This shows your current capacity compared to the original factory capacity. If it’s below 70–80%, it’s time to start thinking about a new battery.
