That is true except for AGM style lead acid batteries. AGMs get you most of the best traits from of both starting and deep cycle worlds, but flatten the wallet.
They don't have quite the long term life expectancy of a true deep cycle battery. On the other hand they can put to shame most battery styles in long term high current output like winching would need.
