For several years, I faithfully plugged it on a schedule in to make sure that the readout was FUL as directed. But the first time I needed it, it failed to deliver enough voltage to even turn on the radio. I had to find another car to jumpstart mine. On the last page of the manual, they tell you to short it out with the cables and then test it. The manual then tells you that if the voltage is low, the battery is bad. SO WHY DID I DO ALL THAT CAREFUL CHARGING? Piece of Junk!
