Lead acid batteries will fool you. They will show full charge and even act like they're taking a charge, but will have zero capacity. That's why a voltage check only shows half the story.
Exactly...
Quick check is to measure the battery (s) with no load and no charging. remove your shore power.... Then while watching the voltage turn on your lights one or two at a time.. If the voltage starts dropping .1 or .2 that might be ok, more than that is deep poo! Then turn on a fan... If your battery voltage drops more than around .4 you have a battery problem or a charging problem... or both.
