What should a fully charged RV battery read?
12.6 volts
This can also be measured with a voltmeter at the battery terminals. A fully charged battery at rest (no load or charging being done) should read 12.6 volts or higher. A 75% charge should yield a 12.4 volt reading, 50% charge would be 12.0 volts, and a 25% charge 11.7 volts.
