I don't think this blanket statement is 100% accurate in all circumstances.
Specifically a lead acid battery using a battery discharge tester must be able to maintain a specific voltage during crank, even on a full battery if you can drop its voltage below a certain point even while it is full it is like sulphating the crap out of it locally and it can cause shedding. (aka the reaction can't occur fast enough)
But this is true of any battery regardless of whether its trolling or not.
