Battery testing with a USB-IO24 cable

USB Battery Tester
Testing batteries is a fairly common task among electronics enthusiasts. Instead of using a complex stand-alone meter, you can put the intelligence of a PC to good use for this. This is not difficult, thanks to the general-purpose PC connection provided by the USB-IO24 cable presented in a previous edition of Elektor magazine. The only thing you have to add is the battery interface described here.
