Miniature Jump Starter

I bought one of these, very overkill for my dart.

It works flawlessly. I went oversized so I would not be taxing it.

It only takes about 40 amps or so to turn over an engine and it only needs to provide that for a few seconds.

As stated earlier LI batteries can pack slot of energy in a small space. And they can discharge a lot of that energy in a short amount of time.

The biggest issue with them is internal drain, of left on the shelf long enough that will have no charge and may not be able to be recharged.

The noco unit asks to be charged every 3 to 6 months.

My daughter is at scho in SD. over Christmas break (5 weeks) her taurus sat outdoors.

When she got back the battery was dead. She hooked up the novo unit I bought her and the car started right up. She took the noco off and then proceded to drive away she turned the headlights on and the car died.

Jumped it again and ran it at off idle for 30 minutes before she could drive with the lights on. It took a week of 30 to 40 minute drives to get it to start on its own. Best money I ever spent on her.
