I have one almost as old and it is slowly making its way towards the curb! It still starts the truck and holds a charge for about 2 weeks. Much longer then that and it is a rough time.
15 years, time for a new one. The old ones were good, but not that good.
Nice to see an online presence from Optima.
I've had decent luck with Optimas over the years, and I'm due for a new battery for my Bronco, but I'm just having hard time pulling the trigger due to prices....uggg.
I have a pair of red tops in my Jeep that have been in use since 1999 and no problems yet.
