Bought a motor home recently with a 5.7/ 350 CID engine and single Duralast battery. Took battery home to charge while working on all the other problems associated with a car left in storage for two years with bad starter circuit.


Re: the battery- I charged it the conventional way and it works-- for a while. It goes down to about 10.0 volts in a week of non use. I charged it to 100% capacity on my Schumacher charger, then used my Schumacher desulfators for three days on it. Supposedly it ran it up to 100%.


When I put the stress tester/carbon pile on it, the meter read weak after 10 seconds.


I don't know if it's worth it to keep using the desulfators on it or not. Used it for 3 days continuously. I bet it would start a car but the issue is holding a 12 V charge and for how long?


I have battery acid. Probably a specific gravity test and maybe some additional acid might help?


Will let you know after the weekend. During this week will charge it and add acid and do specific gravity test on weekend. Maybe it needs a longer
duration of desulfying.
