NET Framework v2 is required to run the program and once installed you don’t run an executable to start the program, but right click on the task bar -> Toolbars -> BatteryBar.
The battery graphic will change color depending on its status, blue means it’s on A/C power and charging, green is high charge, yellow is medium and red a critical battery remaining. This is accompanied by a popup status window that offers valuable information such as charge percent, capacity, charge / discharge rate, charge time left and a wear calculation.īatteryBar also learns about the the discharge rate of your battery over time, and therefore the more you use the program the more accurate it gets at calculating the minutes left value.

BatteryBar goes for a more user friendly approach and displays a very convenient graphical status of your laptop battery in the task bar which is much more readable than the Windows tray icon. This utility displays less information in terms of numbers than BatteryInfoView, but still a lot more than what Windows provides.

From here you can see the charge or discharge rates over a period of time, and because the log records standby and resume, you can see how much the battery has discharged while in the low power state.īatteryInfoView is a tiny portable executable of under 100K and is compatible with Windows 2000 and above. In addition to the main battery information window, pressing F8 will show the log window which is updated every 30 seconds and gives you an idea as to what the battery has been doing. Details such as the manufacturer and model information, power state, charge and wear capacities, charge / discharge rates and times and also temperature can be displayed and these values are updated every 10 seconds.
There are around 20 different values that can be shown, but it depends entirely on what your battery can provide as to how many of these are available. Here’s a selection 5 of freeware tools to extract much more useful information from your laptop battery:īatteryInfoView is a handy little tool from Nirsoft to display the status and information values your laptop battery is capable of offering. What you need is a 3rd party utility to get hold of this extra information for you, and like most things, there are a few around to help get hold of it. A lot of laptop batteries actually have a more information to offer than Windows decides to give you, so it’s there but you can’t get at it. Windows can’t give you any idea why your battery isn’t holding a charge for very long, or if it’s starting to show signs of wear. That might be enough for most people, but sometimes it’s useful to have a bit more information than that. You might also get the battery model and manufacturer if you’re lucky.
Other than that, the laptop battery status and detailed information is pretty much non existent. The most you will usually get is an icon in the system tray, a charge percentage and a time remaining before it discharges completely. The battery in your laptop might be an important component that makes your computer tick while it’s not plugged in, but Windows doesn’t exactly give you much information about it.
