If you do not have a AGM charger (most of us don't) bench a good wet acid battery and your optima. Use a set of jumper cables to parallel (+/+, -/-) connect the two and then connect your charger to the wet acid battery. This will fake out your charger so it will read resistance. Charge at 10 amps until fully charged and then switch to 2 amps over night. I was in the battery business. I was always cherry picked Optimas from the scrap pile after putting them on a digital tester. If they showed any prospect of recovery (6v+) I'd use this method. I had better than 50/50 success at it. Most people did not know how to revive these things and replaced them. All of my vehicles had them and the extras were easily sold off at a pretty fine profit margin.

sorry but that is not correct. mtr homes have 2 different battery applications. living area are deep cycle. chassis battery is no different from any other chassia

and i was referring to a grp78 which is a cranking battery
point is a spl batt is not required for the op application. he may just want something that is hi tech. hi tech is the norm from what i see here

I've heard this technique worked in a pinch, I didn't know it was actually a good way to do it lol. Awesome, I've got another "background" project for the weekend.

I'm leaning this way. I think they have the cool factor, they're available in group 24.

A group 34 is a good fit for your truck, I used a 78 which is the same but with dual posts.
