<DIV><FONT size=2 face=Calibri>That said, it appears that those have been
severely abused and have probably gotten heavily sulfated at best, and totaly
ruined at worst. With enough abuse, you can destroy anything, no matter how
good. With the genset at 40 volts, that is about 5 volts below the absolute
recommended minimum.</FONT></DIV>

out about 1/5th of what was advertised.</FONT></DIV>

orphaned 48 V off grid system that is only 1 1/2 years old, with 40 Concorde
Sun Extender batteries, which are for the most part, shot (about half of them
under 10V after a generator EQ charge). I’m sure the batteries have been
abused at least after the point that someone lowered the generator start
voltage to 40V. We’re still doing fact finding on the charge parameters
for the PV and wind, but I’m wondering if there is anyone that has an opinion
on the Concorde batteries.<o:p></o:p></SPAN></FONT></P>
