I have a 94 and a 06 Dodge diesel trucks, do they really need two batteries? I can get 900 cca 3 year battery from WalMart. Opinions?
 
Go ahead and take that new 900 CCA Walmart battery to a real parts store (not O'Rielys, Advance, Pep Boys, etc.) and have it tested. Then compare it to one of their new batteries of the same group size. The difference will be shocking. We've had several Walmart technicians get batteries from us because they refuse to buy a battery from the place they work.
 
Everstart batteries at Walmart are good a lot of different brand batteries are made by the same manufacture
You are correct, there are only 2 or 3 different actual battery manufacturer's still around. They just slap a different label on the outside for whomever they are building for that particular day.

If it never gets cold where your at, you might be able to get by with one battery. As far as the Everstart battery, we call them neverstart at work. I see more of them bad than good. I use a lot of A/C Delco batteries and they are made by the same company that makes them for my local Autovalue auto parts, but I see more go bad from the auto parts than Delcos. They can be made by the same company but to different standards.

This is what I really meant and should have said in my previous post. Although there are only a couple of manufacturer's around, they build the batteries to the spec of the company that ordered them and then slap the proper label on for that company.

Same as with major appliances, Whirlpool makes a large number of different company's washers/dryer's/refrigerators but specs them accordingly and then puts that company's name on the washer/dryer/refrigerator. Same happens with batteries.
 
It says on the side “3 year free replacement” I’ll see if that is correct. I normally get my batteries at the junk yards but Mopars are hard to find with the plus terminal on the left. They’ll last 3-4 years for $35 + core. I haven’t bought a new battery in 20 years, about the time price went through the roof.
