Query: deltran 1.25 amp battery tender

This charger/tender works exactly as promised. I like the fact that you dont need to babysit it. My only concern is that it gets very warm while charging my trolling battery. That may be normal but should there be a problem, there is a 10 year warranty. How many products do you know of which have THAT?
