On your battery on your tow vehicle there has to be a hot wire going back to the seven pin. This would charge your Escape battery when going down the road. On my Highlander this wire is equipped with an inline 40 amp fuse. It is not factory. This hot wire got accidently shorted. The fuse blew. I was loosing Escape battery power ( less amps) when out west last summer. I put in a new fuse. Batteries in Escape started charging again. See if you have a fuse and power going back to the seven pin. That's all I got.

Don't know where the fuses are. Actually I realized that I bought a new car battery in the intervening time. Wonder if that needs something to do with charging the trailer.

Terminal illness

Check the positive terminal on the battery. . Is there a smaller wire attached in addition to the big thick one? Does it look factory or aftermarket. Is there a fuse holder that pulls apart? It should be about an inch square and 3/8 inch thick. Mine has a Maxi blade fuse. 40 amp. Pull it apart if you have one and look at the fuse. Replace if in doubt. About $4. Auto zone etc.

Before connecting to a charging source, the trailer's battery will be at something less than 13 volts. When a working charging source is connected, it will rise to something above 13 volts... and when the charging source is disconnected the trailer battery voltage it will go back down to under 13 volts (but higher than before charging). You don't need a long time to check this - just a voltage reading in the trailer (and not just the lights common on tank level displays).

It could... if the trailer charge line comes directly from the battery positive terminal, and if the person who changed the battery removed this connection and didn't replace it.

You could do a sanity check to see if there is power going to the 7-pin connector on your tow. With the engine running there should be roughly 14 volts between pin 1 and 4 on the connector sockets. If you google "7-pin trailer wiring diagram" you can see what the complete pin assignments are.

I can believe that the connection was removed. That would certainly account for it. I will look for a loose wire!

Yes, when I charged the batteries before, they were well below 13 and went up to 13 or 13.1 in a few minutes. Then, of course, back down to maybe 12.65 in not long. Which is what I would expect. No such thing this time. I use a 12-volt tester. I don't even think to ever look at the battery monitor with tanks. Thank you!
