sopke with Simon at Rolls Battery, and he advised me that my batteries
are "sulfated" because I am not charging them to a high enough voltage
(28.8v). He further stated that it is sensless to replace the

testing you recommended, and I still have the same result, only 27.3
volts from the charger.
Gary, do you use Skype??? Can I Skype you?
Thanks again, Tony
