How to know if my laptop needs battery replacement?

Posted on 19-11-2023




Little Battery Backup time

One of the most obvious signs it may be time to reassess your laptop battery is if it dies much sooner than it used to. On average, a full charge should produce about six hours of power or longer depending on the programs used. If your laptop is barely making it past a couple hours, it’s likely a sign the battery needs replacing.


Unexpected Power Issues

While the occasional glitch may not always signify battery issues, be sure to make a note of how often your laptop powers down on you. If your Mac or PC powers off unexpectedly, and especially after a recent charge, you can likely assume a faulty battery is the cause. Try charging your laptop again, but if the problem persists your battery may be out of juice permanently.


Slow Charging

In addition to issues stemming from charging, it may also be a warning sign if your laptop charges exceptionally slowly. A healthy laptop battery will charge quickly and retain its power when disconnected from the charger. If your laptop is charging at a snail’s pace, or even worse- only charging when connected to the outlet, you may need to replace your laptop battery.


Overheating & Battery Swelling

All laptops are designed to cool themselves during use and dispel excess heat. If you notice your laptop is hot to the touch, your battery is likely working too hard and unable to cool itself. Often, an excessively hot laptop will also be noisy since the internal fans are working overtime to cool the gadget. NOTE: Always unplug your laptop and stop use if the machine is overheating to avoid further damage.



While there are many great options for both Mac and PC fans on the market, no laptop is designed to last forever. If you’re experiencing power issues with your device, it may simply be due to its age. Generally, laptop batteries become problematic after 1-2 years or 300-400 charge cycles. If your laptop is older, your battery has likely been living on borrowed time and is ready to be replaced.


System Report

In addition to performance issues, most laptops are already equipped with technology to check their overall health. For Mac users, expect to receive a battery service warning when service is needed. For Windows users, consider generating a battery report to check your battery’s health. Depending on the messages from your laptop, you can easily determine whether it’s time to replace your laptop battery.
