Well thought out from A to Z. Comes with 3 styles of battery connector that unplug from the cord. One is on my boat, one on my lawn tractor and one on my spare battery. I rotate the charger between the 3 batteries and never have to disturb the connectors. It's tough, It's waterproof, It's Smart, It doesn't overcharge and I don't even have to think about it.

Calling this charger intelligent is kind of funny. This is just a standard automotive charger and does not work very well. My biggest concern with charger was the charger voltage which was always around 13.2V, and just not enough to recharge a 12V battery.
