My optima is the factory one I got with the vehicle in late 2009, but I do look after my batteries. Make sure your charge voltage is only 13.5-14.2V as anything higher will cook the battery and lower will undercharge the battery and lead to sulphation.
Some early JKs had incorrect charge voltages and they went through heaps of batteries until they mentioned it to the dealer and they re flashed the ECM to solve it.
Additionally, no alternator in modern vehicles are good at charging batteries. Typically the charge voltage drops off too early causing batteries to be constantly undercharged and again, causes sulphation. Once a month or so I throw a ctek charger on my battery to give it a full charge and hence nearly 6 years out of my battery.
