AGM battery question for the experts.
I will readily admit, I’m not a battery expert, let alone AGM batteries. I have a (to me) real puzzler, maybe it’s just chemistry I don’t understand. I have a ‘powersports’ battery, an ETX20L if i...

You have a bad connection somewhere inside the battery, that has very high resistance. When you are measuring the voltage with the meter, you aren't drawing any current, so there is no voltage drop across this bad connection. As soon as you load the battery, it is pulling current so there is voltage drop, which is why you see the voltage at the terminals drop to near zero.
This is probably not recoverable.
