Hi, it depends on how you use it. When you don't need it, just put the ON button to OFF, usually, it can hold at least 3 months.

Answer:
It's long enough to connect to the Positive and negitvie battery terminal on the battery. About 4" and 6" long. If you need to connect a grounding spot. i dont think it's long enough. Or you can connect it to your jumper cable if you have one. and that can extend the length.

Answer:
That is because the engine has been cranked for more than 4 seconds. Or the jump starter has not been cooled down for 30 seconds after each use. Please e-mail me directly, I will send new cable to you.

Answer:
Its a small button on the plug side of the jump starter cable. Its tiny, so you may need a flashlight in dark (there is one built in to this unit).
