Optima released a new Group 78 RedTop for the TB. It is a direct swap now. The only drawback is the $179 price...and the posts that say Optimas are not what they used to be. If I can find one for a little less locally, I am going to try it.
I work for an Interstate batteries distributorship, The yellow top can work, but if your not going to use the top the best battery for our trucks with the best warranty is part #MTP-78! It has a 30 month free replacement with a 85 month pro rate warranty! This is what I put in my 06 TB LS! I hope this helps you any more battery questions just pm me!
