optimas can be discharged down to 0 and then still recive a charge from an alternator... a normal battery can only be discharged to around 70% without doing damage to battery. so if you have a 100ah battery you really only have 30ah that is usable whereas my optima has 66ah and can use the whole lot safely time and time again without damage. if you discharge a normal battery more then 5ish times it will be stuffed.
Interesting.
