they were at about 3.1 v each for god knows how long... but they are the
http://store.solar-electric.com/pvx-6220.html SAME model number but
different shape. Currently they are all the way up to 11.5 v on my 2/6/10 A
Vector 3 stage charger... But finally they are not triggering a fault code
and the charger is actually blasting 10 A (@13.4 V) So I'm pretty hopeful
that they will survive the deep and long neglect. I believe they may have
been never used. They are about 2 years old.
I've read some things and I believe that esp. for solar these batteries
might be a very good "cost no object" for vanagon applications. I just
wonder if they charge for as many cycles as flooded cell golf cart
batteries. They are specced for deeper cycles, much greater efficiency,
lower internal resistance and good interfacing with alternators.
