I run DEKAS now in everything. The new mexican built OPTIMAS have been failing left and right just after the 2 year warranty, and many say that is why they chenged from a 3 year and another 3 years of pro rated to just a 2 year thats it warranty. There have been toi many to count that just die and won't come back, and they are also having alot of them crack around the battery posts and leaking out in extreme heat. Just another victim of johnson controls price cutting. If you buy a wally world special or an advance or autozone battery, they are all the same thing. I buy mine from CARQUEST as they sell only DEKA batterys. they cost a little more, but I have had to many to count go for 6-7 years without incident.
