Simple way to measure coach battery capacity
I'm looking for a reasonably simple way to measure the current capacity of the single coach battery in my newly purchased (used) RV. I have a basic voltmeter which I don't think will be much help, ...

A significantly capacity impaired battery will fall flat on it's face when a load test is conducted. Thirty seconds rather than the BCI 15-seconds. Sample electrolyte clarity and density and call it a day. Ten minutes rather than many hours. Doing a spectroscopic analysis of the debris in your radiator bug screen would be on par with PT'ing something nearing terminal failure. If the effort is for self-education my comments here will summarily do an abrupt 180 degree reversal. But exploratory testing is best performed on other than a mortuary bound corpse
