    Here is a photo of my battery.

    Interestingly, I contacted Panasonic customer support and they say that the CF-VZSU46 is no longer being produced and the new version is CF-VZSU46AU
    However it looks like there is a date code on the side of the battery that is July 2018. So I wonder could this be a counterfeit? Or maybe that is the "good until" date and not the production date?

    Thanks - Kevin

    FYI ...That is not an original Panasonic battery. That is an aftermarket one.

    Well it looks close but it's not the same as mine. The top sticker is going the wrong way and there is a barcode missing

    Shawn - How can you tell that my battery is not OEM? Matsushita Electric is parent company of Panasonic.

    Yours is a counterfeit made to look like an original Panasonic product.
    The stickers are printed wrong.
    It is also missing the small barcoded sticker .
    The color of the blue tab is wrong also. Notice mine are opaque and I can see through yours?
    Yours is missing the UL certification markings.


    See the circled sticker in photo.
    Your battery even has an indented place where that sticker is supposed to be.
    That came from when the Chinese clone factory made a mold from an original battery.
    That sticker is on EVERY original Panasonic Toughbook battery that I have ever owned.
    That tells the manufacture date and probably the serial number of the battery.

    Try a full reset. Which means you need to take all out the supply line. The main battery, unplug the AC of course and pull out the cmos battery for atleast 30 second.

    Hope it helps. If your battery is displaying a flashing red. It means your battery is kapot.

    Interesting the way they covered the spot where Panasonic would have been displayed.

    I found some 53 spare parts. What is your model # or mark. I'll dig the box out if you are interested.

    I thought maybe you converted to Dell or Macs.
