Anyone using AGM batteries in your diesel truck for starting? My2005 dodge ram with the 5.9 diesel engine will need two new batteries soon.If so what brand do you recommend? Thanks
Use 4 of em' in our transit buses. They last about 3 times as long as standard lead acid chemistry batteries on the average in our usage cycle (and we're extremely hard on them). We'll never go back to lead acid.
Brands we've used are: Odyssey Trojan
and in my personal life I've used Optima red tops as well.
Just make sure when you switch to an AGM battery that isn't the same group number/size as your current ones, that you have enough cold cranking capacity.
