I used to put the local farm and barn batteries in my tractors, but got real pissed after they seemed to start crappin in a year!! then I switched to "ironsides"cost more but almost 400 cca, and have one going on its 6th year!! As for the truck, i store mine in winter (i know what a loser, but its old and i spent lots of hours on it in my defense
) so i just do the exact same as what Don said above...the old lady's van has a napa battery going on its 8th year in it...Id probably stick with the delco if i was in your shoes...sounds like its been good to you...
