I bought my 1980 truck new. The OEM Delco "maintenance free" battery caused terrible corrosion on the battery tray and front end sheet metal (arrgh!). I rebuilt the tray, cleaned up and repainted the sheet metal. For the last 20 years I have been using Interstate batteries in the truck with no problems (no further corrosion).
Is there a difference between the Delco and the Interstate? Would the size/capacity of the battery help prevent overcharge/boil over?
