Battery/ charging question

OK assuming your charger or inverter is working 100% then you have a shorted / bad battery ; its a definite proven point that generally speaking TWO 6 volt battery's are better than one 12 Volt battery's
and of course FOUR 6 volters is best over two 12 V batterys

4 big 6v much betta, when you have room.

I use 12v. Some good reading

Probably been that way for 7 days yep :)

Same as what's there. AGM if you can afford them.

BUT you NEED to get the converter problem fixed first. The batteries that are in there might still be good. A healthy external charge should tell you something about that.

Also if I turn on the generator I get 12.3 but if I start the engine I get a 13.3 reading?

All the evidence points to a failed converter/charger.....or a blown fuse for same.

13.3 is about the minimum to actually put some charge into the batteries.

If they have not been charged properly for long enough, the batteries themselves might be bad now too.

One of the most likely causes of a low battery reading when you are plugged in and your converter is working properly is a bad connection from the converter to the battery. It could be either the positive or the negative at the battery end or the converter end.

Verify your converter output is over 13 volts first by putting your meter leads right on the converter output terminals
, then connect a wire to the converter negative terminal and use your jumper cable on one lead to the battery negative. Does that make the battery voltage match the converter? If so, find the loose negative wire. If not, do the same with the positive lead.

In my case, the negative feed on the converter terminal strip was loose, the converter was putting out full voltage, and the loose connection acted like a load, the battery was down below 12 volts before I checked it out with my meter and fixed it.

Batteries week.

Have the batteries load tested at a battery store. If OK you have a bad charger, blown fuse, tripped CB or wiring issue. A 12.3V battery on shore power should be charging in bulk at 14V+ and drop to 13V+ float voltage.
