Can complete discharge of brand new batteries kill em? Did I just blow $160
bucks by leaving the key on in my recently revived diesel?  The truck (f250
powerstroke Ford) got two Interstate batts.  I found it this morning
without even enough electrons to move anything on the gauges or light the
warning lights...Deader than a doornail!  I'm now charging them, or
trying.    Put a digital meter on each, before I hooked it up...read
0.02v....with my battery charger on "manual- 10 amp" my meter is reading
12.00v... I am an electrical dunce, BTW...
