Actually the answer kind of depends... Some folks insist there is no difference between a real Deep Cycle battery like the common Golf Car six volts often used in Motor homes and a Marine/Deep Cycle or starting battery.
Well, in the case of the last two (marine/Deep cycle and starting) they are right, there is not much difference.. but a real live deep cycle battery like the Interstate U-2200 (I hear it's got a new number now) GC-2 format, Golf car battery.... can survive such a goof, (Mine have and so has at least one other in this thread) it will take time off their total life, But they can survive.
A starting type, including Marine/Deep cycle... Not so well.
Home is where I park it!
