Power Draw? New AGM group 34 Batteries

89' 25' Ecella Decided to go camping only i found that my DC was dead.
Found one of the Optima Blue tops (5.5 yrs old) hada dead cell.
Bought two new Batteries Plus GRP 34/78 AMGs (they said they outperformed the optima’s (we'll see)
Found that they only lasted a couple hrs and where drained empty.
Had two overhead lights and a fan on (this was for testing) and three hrs later batteries are drained.
My intelipower 9100 provides 45 AMPs of power (more than enough to charge these quickly. They only charge to 3/4(a clue?)
When i test the batteries they show 13.5 v when plug into shore power.
when unplugged from shore power they both showed 12.8 v
I found that when I tested from frame to POS i get may 13.5 or 12.8 volts respectively.
When I test DC from frame to NEG i found something interesting:
The battery on the Street side (drivers side) shows .001 volts from frame to NEG post.
The Door side (Passenger side) battery shows .9xx volts ???????
Could this be my problem or is this within specs??


rv battery .9 volts from neg terminal to frame
