A TRUE "Deep Cycle" group 24 batter would offer about 60 amp hours at the 20 hour rate, around 400 CCA and weigh in at around 55 lbs.
It would never sell.
But a well made battery of this ilk would charge faster, get to 100% charged easier, not sulfate as fast, require far fewer incidents of equalization, and have double the lifespan under rigors of sustained 50% discharge recharge cycling
And it would never sell
An inexpensive Load range G racing tire...
But regardless...
Good batteries are made better with denser more expensive plate paste. So the cell electrolyte does not imbalance as easy. So charging cell-recovery is easier. If you do not mind a lifetime odyssey of goosing the battery that last ten percent when the battery is working hard for extended periods of time then go for cheapest.
