Duralast Jump Starter Wont Charge. An indication of a battery going dead not empty but dead is the change of the red light into green in a very short time when you attempt to charge it from the wall outlet. A Duralast Jump Starter 750 Amp has no AC charging adapter. So after this video I went back and checked to see how far along it did end up charging. The AC adaptor or USB cable could be bad.
Check the cord for damage. But 7 years has taken its toll. It happens with our other portable devices. I am so disappointed. There is an LED display in the Duralast. The jump-starter is designed to give your battery a quick boost of power allowing your cars engine to start.
However the jump starter wont do much good if it too is dead.
Sadly the short answer is No. Charging light will not come on when charging from the vehicle DC charge only 2 hours at a time it will damage your jumpstarter battery if plugged in for any longer. It then smoked for over 30 min while it continues to. My device died stopped holding a charge. Here are the steps you need to follow. Your brand new battery-jump starter will not charge your car battery.
