12V Meter Curiosity......
Curious.....under charge the digital meter reads 100%.... 13.6V. At rest, fully charged....84%.....12.13V And the trailer "gauge" shows 100% What do you think?

If you're confident that voltmeter is accurate then I would trust it. Since you're measuring 12.13 volts with a surface charge then that's a good sign that something is amiss with the battery. I wouldn't trust the trailer gauge at all. It probably reads anything over 12v as full by design. The percentage meter seems to be off by quite a bit as well. 12.13v would put you a little over 50% capacity.
