I've actually had good luck with the OEM (Mopar) Battery purchased from the dealership. I am sure it is a re-branded to Mopar battery, but the last two I have had lasted over 5 years in hot Texas! Reason being, I keep my car on a battery tender--they work great. After 15 years of ownership, I've only bought 2 batteries. Sorry, I don't have the Mopar Part number and too lazy to look it up. That said, I paid around (only) $235 for each of them at the Dealer. That's pretty good bargain in my opinion. Happy hunting. I'm sure those optima reds are $500+...... Just my opinion, but I've had good luck (saved some good money). Just buying Mopar OEM and installing myself.
