A deep cycle car battery is one that will last a very long time. Unlike more common car batteries, the plates are very thick, so a lot of charge can accumulate. This type of car battery cell is typically used on golf carts, though you can also get one for your standard vehicle. These batteries differ from a standard car battery, as they do not release their power in one surge, which is needed to start the car. Instead they release their charge over time.
