replaced the batteries in my 2005 dodge diesel last year,
on a cold morning they were getting a little slow,
I when with autozone, duralast yellow tops 850 cold cranking amps, which is 100 cca more than the originals.
$139 each and the boys did a very good job installing the batteries.
each battery has some type blanket or wrap around blanket that made it more difficult to install the batteries. They took care and every thing when right back into place as it should. they also checked the battery cable ends and put the proper lube on each post.
I kept the old batteries and planned to use them on my boat, but by spring they were both dead.
good luck,
you do not want to be forced to change the batteries out in the backside of no where or have to install the wrong size battery as no-wheres-ville does not carry your size battery.
also change out both batteries at the same time and be sure to check out the battery cable ends!!!!!!!!!!!
