The Duralast 750 Jump Starter is notoriously fickle when charging with the built in charger. I did a quick 'mod' to add an SAE connector that connects into a digital battery charging unit for quality charging and battery state maintenance when not in use. **This will break any warranty you have on the unit, and I am not responsible for any issues, failures, or destruction of the unit if you try this. Please take your time and be safe if you try it.
