You know Batteries Plus is the place to go when you need your cell phone battery replaced, but did you know that we can install batteries in your other devices too? That’s right, our stores offer battery replacement service for a wide range of laptops, tablets and e-readers. Find out how to track the status of your batteries and learn when it’s time to get them replaced.

How Long Should my Battery Last?

Let’s start with battery life. How many years will a tablet battery last? For tablets you can expect the battery to last roughly three years. An average laptop has a battery life of around one to two years. Keep in mind that these are just averages and that your experience may differ.

How to Check Your Laptop Battery Health Directly

Both Mac and Windows laptops have a handy feature that allows you to check your battery life directly to see how much life it has left.

To access this on a laptop using Windows 8 or later, use the following method:

  • Select the start menu on your laptop
  • Search for and then select “PowerShell” from the menu that appears
  • Type the command: powercfg/batteryreport into the window and press enter. This will run a report with the information you want.
  • Go to Users/Your Username folder and look for the battery-report.html file
  • You’ll find the battery health info in the “Battery Information” section of the report under “Battery Life Estimates”

To access similar information on a Mac laptop:

  • Hold the Option key and click on the Apple menu
  • Select “System Information”
  • Scroll down to “Hardware,” then “Power” – You’ll find the information on the right side of the screen under “Cycle Count.”
  • Cycle counts measure the number of charge cycles your laptop has completed. An average laptop has a battery life of about 300 to 400 charge cycles.

How to Check Your Tablet Battery Health Directly

There is a similar way to do this on Apple tablets as well. Simply go to “Settings,” select “Battery,” then “Battery Health.” The Section titled “Maximum Capacity” will give you a percentage value comparing your battery’s performance to when it was new. A healthy battery will have a percentage of 80% or above.

Unfortunately, Android tablets do not currently have an equivalent way to check on health, so if you’re using a Samsung tablet you’ll want to monitor your tablet’s performance for signs that your battery needs replacing.

Signs That Your Battery is Dying

You can also tell when your laptop or tablet needs a new battery by how it is performing. If you find that your device is running out of power too quickly or starts suddenly crashing, it’s probably due to a dying battery. Some other warning signs to watch out for include slow recharge times and overheating. For iPads you might also notice that the tablet’s performance has slowed down.

Battery Replacement Service

If your find yourself experiencing any of the issues mentioned above, bring your laptop, tablet or e-reader to your nearest Batteries Plus. The experts there will test your battery for free and let you know if it’s time for a replacement. If you end up needing a new battery, you’ll find options for all major brands, including laptop batteries for Hewlett Packard, Dell, Toshiba, Compaq, Samsung, Apple, Acer, Lenovo and more, as well as tablet/e-reader batteries for Apple, Samsung, Amazon, Microsoft, Barnes & Noble, LG and Asus products.

Replacing the battery in your laptop takes roughly 30 minutes to complete and costs somewhere in the range of $79.99 to $159.99, while tablet battery replacement service takes around 60 and 90 minutes and costs between $49.99 and $139.99, depending on brand and model. We can even replace batteries in older model tablets stretching all the way back to the iPad 2 and Galaxy Tab 3. Service varies slightly between locations though, so it’s always a good idea to call your local store first to verify that they have the equipment to work on older model devices.
