The charger never shut off. The "Automatic" feature didn't work.  I have another Schumacher charger, older model 10/2 amp fully automatic that works fine.  Just wanted a second charger so I could charge up both of my boat batteries at the same time.  Unfortunately, the one I received did
not shut off.  It also got quite hot, and more bothersome, was my new deep cycle battery, was getting hot as well.  I used my old charger in place and it worked fine, charged up and shut off, going into maintenance mode.  This confirmed the new unit I received was defective.  Made in Mexico.
But, thanks to Amazon's great customer service return policy, free shipping on the return.  My refund was made right after the
returned unit was entered into UPS system.  Not sure I want another one of these, maybe try another brand.
