BatteryBar: The Battery Meter for Windows

Lately, I’ve been looking for a nice little battery meter widget or application to use with my netbooks so I can have a better gauge on how long their last on a single full charge.

The BatteryBar does just that pretty nicely.


It’s got a small footprint, sits on the taskbar and works very well in providing almost accurate information about your laptop’s battery.

The screenshot above is for my HP Mini 311 which I upgraded to Windows 7. It also show how much is the capacity of the battery and the current health (battery wear).

BatteryBar tells me I’m getting around 3.5 hours for a full charge although from experience I was able to squeeze near 5 hours of use on this unit before. Will be running the software on all my laptops now and see how they all compare.

Check out or download the Battery Bar here and let me know how what’s the indicated battery life for you model of laptop in the comments.

Update: There have been questions if this app is reliable. My observation is that the computation of the battery life is based on historical usage. So, if your first 30 minutes of use you play a video then it computes the remaining battery life based on the amount of power consumed vis-a-vis the elapsed time. However, if you changed your usage on the next 30 minutes by just running MS Word, it then recomputes the estimated time remaining based on the power consumption of the last 2 tasks you’ve made with the laptop. As such, you will notice the remaining battery life often fluctuates as you continuously run your laptop.

    This will be great for the MSI wind that you’re about to give away sir yuga. LOL! Sadly my lappie got destroyed during the flood last september and I’m still paying for it (cc) =(

  2. Edgar says:

    The item on battery wear is interesting since the usual battery indicator only shows the remaining power. Quite useful, really.

    interesting app =)

    I’m using an MSI Wind U123, with a 9-cell battery, running Windows XP, and LCD brightness set to 50 percent…

    Using the default battery meter on a full charge, it showed that I have 10:16 (hh:mm) without Wi-Fi and without a wireless broadband connection, 9:39 with Wi-Fi switched on, and 7:53 with wireless broadband connected.

    Using Battery Bar on a full charge, it it showed that I have 9:16 without Wi-Fi and without a wireless broadband connection, 8:51 with Wi-Fi switched on, and 7:20 with wireless broadband connected. Battery wear is at 1.9 percent.

    Hope this information is helpful. =)

    I’m also looking for more accurate battery meter, the widget from the OS doesn’t display the remaining time. Hope this one will work. thank you for sharing

  7. chris says:

    I’ll try this on my netbook. I like the feature where in I can see the remaining hours of my battery.

  8. rbsoriano says:

    This reminded of my brother’s MSI Wind U100. Sira agad ang battery, wala pa namang 1 year un.

  9. KarL says:

    BatteryBar is nice and lightweight, however BatteryCare is most useful. I just thought you ought to know. Check this out:

    Ok to pero mas useful ang para sa temperature kasi meron ng battery monitor ang vista/win7.

  14. alfred says:

    ok na ok toh lalu na kapag gagamitin ang laptop/netbook outdoors madali malaman kung kelan dapat iplug-in na yung bothersome na power cable hehe……weeh sana manalo ko netbuk!!weeeh.

    Win7 built-in battery indicator doesn’t seem to match with what the application indicates. You can see the reading here:

    I’m using Lenovo Y410 T550, 1 year and a half old already. Thank you for this downloadable Sir Yuga!

  17. This is a good additional software aside from the default battery meter on my acer laptop. It even has a battery wear indicator. I wonder if it is accurate?

  18. @ Lito: That’s my exact question as well, I also wonder if it’s accurate. I don’t know why the built-in Win battery indicator seems to have a different reading with the application. Let us hear from others who installing this one on their laptop.

    Tamang-tama download ko na 2 in preparation sa mapapanalunan kng MSI netbook, heheh!

  20. dindo says:

    this app is very useful however wla pa akong netbook sana manalo then ako.. god bless u sir yuga.

  21. Jhay says:

    I’ve been using this app for almost 4 months now. It’s a great little app that offers a wealth of information.

  22. LunaTech says:

    i’ll get it once nakabili nko ulit ng bagong laptop. heheh ayos

  23. liz says:

    nice one! i’ll try this out! thanks sir yuga =)

  24. Brownspank says:

    Would be nice to show support for the original developer and link back to their original website (where they sell the Pro version, too): http://osirisdevelopment.com/BatteryBar/

    I’ve just tried out both Battery Bar and Battery Care, and I’d probably agree with Karl’s comments (dated Dec 13th, 2009 at 5:26 pm (#10))… I ran both utilities side by side. Both seem to be accurate enough (difference of just about 10-15 minutes). Battery Bar is visually more appealing and doesn’t get much in the way of my netbooks 1024 x 600 display. But I found Battery Care’s set of information and functionalities more useful.

  26. Robin Lim says:

    Okay, I installed Battery Bar on my I year old HP Compaq 6510b… battery wear is 0%, which is hard to believe. But lets see after a few days of use.

  27. Patrick says:

    Nice little app. My Lenovo already has a power manager with a built-in battery meter. ^_^

    And I second the BatteryCare recommendation. Helps you monitor your battery’s health thru discharge counts and wear levels.

  28. Leojay says:

    Wow, Abe, this is a great software. Thanks im using it now..I may say great things comes in small packages..this is one great app!

  29. Leojay says:

    Thanks abe! great app! Great things comes in small packages! really helps a lot..

  30. Nonong Tools says:

    I am having some problems with my HP DV6816tx as it drains battery fast when I’m doing presentations or using a second/extended monitor. This application will probably help.
    I’ll also try it out on Acer 4736Z, the unit has great battery life and with this app find out how I can extend it some more.
    Thanks and God bless.

  31. As the author of BatteryBar, I can tell you that the build-in Windows “time remaining” meter is NOT accurate. Windows calculates time remaining based on the exact discharge rate at the moment the battery is sampled. In other words, Windows is telling you, “Assuming the battery discharge rate remains exactly the same as it is right in this moment, your battery will last x hours and xx minutes.”

    The problem is that discharge rates fluctuate quite a bit and batteries discharge in a non-linear fashion, usually slower closer to 100%.

    BatteryBar keeps historical usage data on your battery and keeps track of exactly how long it takes to move from 99% to 98% and so on. With BatteryBar, you can literal watch the timer tick the minutes away rather than getting the huge time remaining fluctuations you get with Windows.

    I hope that helps.
