A bit of a long story.  I am stumped, but can't (unwilling) to do too much on the road.
In Feb, I bought and installed 2 6V AGM GC2 Lifeline batteries.  At home, plugged into 30 amp circuit, my Zamp battery monitor showed 13+v, so I assumed the on board charger (Progressive Dynamics 9260c) was working and charging the batteries.  Now I am on a trip and the batteries wont take a charge, if there is one.  The Zamp monitor does NOT show a 13+v charge from the on board charger.  I hook up an external, stand alone charger (Schumacher ship n sail, or something like that)  It never shows more than 60% charged, and comes back and says "bad battery"  Not sure if the brand new batteries are "bad" or if the PD is not charging.  Assuming bad batteries, and needing to get home to have Batteries Plus fully test them, I bought 1 group 24 12v deep cycle RV battery and hooked it up.  We are on 110 30m amp hook up and the Zamp monitor has gone from 12.9v to 12.4v in 1/2 day.  So it seems the PD is NOT charging.  I will hookup the external battery charger in the morning to see if that works.
I can remove the power center and see the PD.  But getting my hands/arms in there will be very difficult.  And I fear loosening wires in the power center.
As I said, stumped, bummed and frustrated.
Any thoughts/advice would be greatly appreciated!

I didn't see mention of cycling the circuit breaker for the converter.

Your batteries are brand new. It worked at home and I assume you changed no wires on your trip. If you are plugged in somewhere set your multimeter to 20v setting and check what your batteries read. Then check at your converter. If converter is charging but batteries don't see the charge reset all your circuit breakers. If you hook your portable directly to your batteries disconnect converter and check battery voltage with your multimeter you should see 13 plus volts. Let us know what your get.

Batteries Plus is nation wide. Google to see if there are any near your current location.

Reply to several comments. Thanks!!!
I posted in 2 forums. One forum suggested to disconnect the battery via the disconnect switch, while still on shore power. I did, and no 12v lights worked. That implies/proves the PD is not putting out 12v.
I did recycle the breaker switches. No apparent change.
Re: using the external charger. When I hook that up to the new 12v battery, I expect the battery monitor to show > 12.7v. It does not. The battery monitor was at 12.3 this am and did not change when I hooked up the external charger.
But I do believe my small solar panel is helping.
As stated earlier, I am very hesitant to access the convertor because it is very difficult to access, and I fear screwing something up. I am trying to be realistic about my own skills.
Thanks again. I will post updates.

Check the fuse at the battery positive wire outside near the battery. Also, pull the wire off the positive terminal of the battery and check the voltage from that wire to ground.

It's either the fuse or the converter is dead.

Looks like your converter was not working even before you left. Suspect blown reverse polarity fuses from a mistake when installing the new batteries. Easy to check and fix.

When you isolated the batteries to check them and the "monitor" did not change when you charged the batts, that could mean the monitor is also isolated. You need your own digital multimeter set to voltage to put on the batteries directly.

I would reconnect the Lifelines and use the 24 to jumpstart them so the portable charger will begin charging without error. Or use your vehicle to jump the Lifelines.

I assume the Lifeline's voltage has been run down so low the portable thinks they are bad.

Bad battery. Yes, they can go bad that fast.
You may also have blown the protection fuse(s) in the converter.

Sounds like your battery monitor is not working because it is disconnected somehow. Again check voltage with a multimeter at the pos and neg terminals of the battery when using your portable charger it should read 13 plus volts. Let us know what it reads. Do you have a multimeter?
