i got 2 optima red tops 34/78. and the truck had orbital force reactor. the red tops dont seem 2 crank it over *** good as the old ones did. any ones eles got red tops in there trucks?>

 

I had one red top and one yellow top last year.But i had to replace the red top because it couldn't handle the diesel engine and gave me starting problems.So i bought another yellow top and havn't had the problem.

 

Thats not true. The Red Top is the correct starting battery - the yellowtop is a combo starting/deep cycle.

You always need to replace batteries in pairs and they need to be the same. I suspect that was your problem.

 

I have had nothing but bad luck w/ my Red Tops in my toy car (Fiero GT w/ 3800 SC Series II Swap). After winter they were always COOKED. Yeah i probably should have taken them out BUT every other battery was fine doing that to. Starting and running or driving if there was no salt.

 

My bad your right.

 

i had a red top and yellow top in our backhoe and a set in my truck couldnt ever get over a full year out of them between the 100* summers and -20* winters. i run nothing mut interstate batterys now almost at a year in my truck now and still holding up
