PD9245 and Lifeline GPL-31XT testing
I just acquired a Progressive Dynamics PD9245 converter to specifically charge a New Lifeline AGM GPL-31Xt at 125AH capacity. I tested the converter tonight on a different battery, and saw Voltages...

Rolls has their work cut out for them just trying to match the Concorde battery. Sort of like finding a competitor for a MacIntosh tube-type audio system. When you hot you hot.
Well, maybe that's why Rolls chose Fullriver to re-brand an AGM battery for them .... because Rolls considers Fullriver AGM technology as already somewhat of a competitor to Concord AGM technology.
I say "somewhat" because:
Concorde's highest amp-hour true Group 31 size AGM battery (GPL-31XT) delivers 125 amp-hours for it's 74 lb. weight. This gives the Concorde a stored energy per pound efficiency ratio of 1.69 (125 divided by 74). Fullriver's highest amp-hour true Group 31 size AGM battery (DC115-12) delivers 115 amp-hours for it's 72.1 lb. weight. This gives the Fullriver a slightly lower stored energy per pound efficiency ratio of 1.60 (115 divided by 72.1).
(Of course the conclusion from my analysis above may be completely off ... because maybe the more lead in the battery per less stored energy per pound obtained from that lead may mean that the plates are thicker in the lower stored energy battery.)
By the way, I expect that Krell audio gear would give Macintosh a run for the money. ;)
