AGM discharge minimum?
The facility repairing our post Antelope-strike damage managed to run the house and chassis batteries down to about 9.5v. The Optima Redtops are brand-new, but my 8D's are approaching 6-years. Haven't found any guidelines/cautions regards minimum charge levels nor risks of permanent damage. What do you battery experts think? I did have an "E-10" warning on the Heart Interface display, but when cycled during charging it went away.
Thanks!
