AGM Battery Failure

JeffroNC

First boondock situation this year and the OE battery won’t deliver. Using just 30 ah Dropped the voltage to 12. My clue was that the fan on the DC fridge would not stop running because the compressor would not start. 

The BMV showed 89% but the voltage was below 12. The compressor needs more than that to start. The Alde would not start either. 

I hope this info helps someone. 

As Mr. Murphy would have it, I have two 100 ah lithiums sitting at our kids house waiting to be installed. 
We were at a perfect spot, B3, in the Ocracoke Campground with no hookups. 

Good news is that there is another national Park campground in Nags Head right up the road that has 30a power. The journey continues. 

High class problems. LOL

Ugh, I hope to meet Murphy before I die, I am going to put a whipping on him! You will really like Lithium and it will make you wonder why you waited so long. If you boondock, they are the solution!

@Dutch061 After bring an auto mechanic, I have a pretty long list of Murphyisms. LOL
 We are on the ferry to our next spot and my truck got some power into the batteries while we were waiting.

Were you measuring a rested battery?  Voltage will always read low if things are running in the trailer, even on the vaunted BMV.

It was a little hair raising. Great gas mileage though.
