How to Fix Bad Laptop Battery Health Issues

  • If you have an issue with your laptop battery where the cells don’t hold up the charge, the only solution to this factor is to replace the battery or cells.
  • You have to use the original and compatible charger which ensures the full amperes and charge as required by your laptop.
  • The next thing to do if you’re dealing with a laptop battery that won’t hold a charge is to make sure that it’s fully charged. Most laptops offer a little light or icon that tells you when your laptop has fully charged, and you should wait until it says 100% before unplugging.
  • If you still have bad laptop battery health after waiting, there are some steps you can take to fix it. It might seem like an obvious solution, but one of the easiest ways to get more life out of your laptop battery is by making sure that you aren’t taxing it too much in general. Make sure that you don’t leave apps running in the background while you’re not using them, and close down any programs or tabs that you aren’t actively using on your laptop. Your laptop will use less power when it isn’t running unnecessary processes, which will extend its overall battery life.
  • You should also try adjusting your laptop’s settings to reduce how often it goes into sleep mode. When your laptop goes into sleep mode, it uses up battery power even though you aren’t actively using it; turning off sleep mode could help prolong your laptop battery life considerably.
  • Finally, keep an eye on what kind of charger you are using for your laptop—if you notice that your charger isn’t working as well as it used to, consider buying a new one.
  • And lastly, just remember to avoid overheating the laptop, keep it cool while using it in a cool atmosphere (such as an air-conditioned room) whenever possible.

Can I Use Another Laptop Battery Instead?

If your laptop won’t charge or hold a charge for very long, you may be able to replace your laptop’s battery with a new one. When shopping for a replacement, look for batteries that fit snugly into your laptop.
You can also purchase a universal laptop charger, which will allow you to use any compatible laptop battery on your laptop. However, some laptops are made exclusively for certain types of batteries and chargers; if you have an older model computer, it might not be worth it to invest in new technology just yet.
If you do decide to buy a new laptop battery, make sure it fits snugly into your laptop before buying. Also, check that its voltage matches up with your original battery (if possible).
If you choose to buy a universal laptop charger instead, make sure that it has all of the correct adapters and cables needed for charging different laptops.
Before replacing your laptop battery, ask a knowledgeable salesperson about your specific model. He or she should be able to tell you whether there is enough room inside your laptop for another battery—and what type of new laptop battery would work best.
Remember: if you aren’t comfortable doing any sort of repairs yourself, take your laptop to a professional technician first and get his or her advice on how best to proceed. Replacing parts without knowing what you’re doing could result in more damage than good!
