Deep cycling performance depends on the battery chemistry. Most cars in the US use a type of lead-acid battery that can't be deep cycled even a single time without serious risk of damage to the cell. I would assume this is true of any lead-acid battery not intended for deep cycling everywhere else in the world too as it adds significant cost to battery.
