Good in the heat (at least for me)
I live in Phoenix, Arizona -- 110+ in the shade on a regular basis.
I learned a lesson from my wife's car in this heat. Got a cheap Checker battery. They died every summer but I always got a replacement for $10 or less. Problem was my wife always got stranded somewhere every summer plus the hassle factor. After a few years of that, I popped for an Optima and it's been there for the last 7 years. Still going strong.
When the first factory battery went bad in my Ram, I popped $200 for a pair of Optimas without even flinching. That pair is still going strong after 4 years.
Can't say enough good things about them. The never corrode, they never leak, that last and last (even in this heat).
If you're going to keep the truck a while, buy a pair of Optimas -- you'll only cry once.
PS.
You can get blems for around $80. The only difference is the warranty starts on the manufacture date instead of the purchase date. The Optima website shows how to read the manufacture date code off the battery. When I got my wife's I went down to a battery dealer that carried blems. He let me in the back and I dug around until I found one that was only a month old. I think I paid $75 for it.
