Batteries will slowly die no matter what - even if you put your battery in a closet and never touched it, it would slowly lose capacity due to age. Heat, usage, age - all of these things are bad for batteries. Laptop batteries decline due to a number of factors. RELATED: Debunking Battery Life Myths for Mobile Phones, Tablets, and Laptops Why Your Laptop’s Battery Capacity Declines If you don’t, you may replace a battery that’s still in good enough shape. If Windows says it’s time to replace your battery, be sure to calibrate it first before checking its actual wear level. The battery didn’t actually gain any additional charge, but the calibration helped the battery’s sensor actually detect how much capacity was in the battery. Windows warned us that it was time to replace the battery and the battery appeared to be at 27.7% wear level according to its reported capacity.Īfter we calibrated the battery, Windows stopped warning us and the battery’s reported capacity went back up to 70.8%. For example, we had a battery that reported it was almost dead. The information above may not be completely accurate if your battery requires calibration.

However, the battery’s current capacity at full charge is only 61,261 mWh. NirSoft’s free BatteryInfoView does this well, displaying the battery’s approximate wear level, the capacity it was designed to have, and the capacity it currently has.įor example, in the below screenshot, we see that the battery was designed to hold 86,580 mWh of energy. If you’re curious just how far your laptop’s battery capacity has declined, you can use a third-party tool to view it. How to Check Your Laptop’s Battery Capacity Note that this warning was added in Windows 7, so you won’t see it if you’re using Windows Vista or XP. You’ll see a red X appear on the standard battery icon in your system tray and, when you click it, Windows will inform you that you should “consider replacing your battery.” Windows also says that your computer might shut down suddenly because there’s a problem with your battery - in other words, your battery can’t hold enough of a charge to power your laptop for long when it’s not connected to an outlet. As you use it and it weakens, you’ll just notice that your laptop doesn’t seem to last as long on battery.Įventually, when your battery reaches a low enough capacity level, Windows will warn you.
