Energizers Duo really stood by its products name. Should you have been one of the lucky purchasers of the Energizer Duo battery charger you may have inadvertently downloaded a virus along with the software that allows you to watch your batteries charge. It basically Duo’d as a charger and virus spreader.
It seems that the download-able software program will infect windows PC’s with malware that opens up the 7777 port to telnet and the like. This can potentially allow hacker types access to the users computer to list, download, upload and execute files. None of which you generally want to allow them to do.
It uses UsbCharger.dll to run Arucer.dll and also ensures that the Arucer.dll runs every time the computer starts up. If you uninstall the Energizer charger software it will remove the UsbCharger.dll which stops the Arucer.dll form being called, though it remains on the hard drive. You can go and delete the Arucer.dll file after uninstalling and when you restart it’ll be gone for good.

The lead acid battery has been around for well over a hundred years, but it still remains the most commonly used and best suited battery for a variety of applications. Though it’s an old (the oldest) chemistry it is finding wide usage in the field of renewable energy, batteries of the newer chemistry types such as lithium, Ni-MH etc would cost a fortune to produce in the size and volume needed for RE applications. Also lead acid batteries respond well to Deep Cycle uses and can recover well from a much lower charge than some other chemistry types.
