Getting my father's 2005 dodge ram 5.7L 4wd 1500. It has a 4 year old Farm & Fleet (Johnson Controls) battery that was poorly kept over the past 3 years after he became parapalegic. It was run for about 30 minutes once a month appx. so it has been maltreated and never taken out in winter time over this period of minimal use. It currently somehow still starts the truck, not robustly but starts it indeed.
I don't want to ruin a $300 alternator for a $80 battery.
It is appx. 700 -800 CCA top post. Any genuine way to top it off with charge to make it whole again or is it likely a sad excuse for what it once chemically was?
Any charging regemine you recommend to top it up? A formula?....A certain amps over certain hours per hundred CCA?
