for a long time i swore by optimas, but seeing this one fail a test so soon has me concerned with the quality

Most all batteries I have ever used started to slow after 3 years anything more than that is extra I don't really expect any off the shelf battery to do any better than that and any new battery will make your truck crank over 600 rpm even the cheepos.

Yes. That's the "31" part of the part number.

I read somewhere that autozones yellow top batteries were one of the better ones as rated by Consumer reports.
