Measuring battery condition
Easiest way to measure battery level of charge?
Forum Discussion
There is the right way (install a proper voltmeter), and then there is my way -- I disconnect the battery. Let it sit for 15 min. Take out my little multimeter and hook it up.
They say you need to leave the battery resting for quite a while to get an accurate reading. But I tried taking a resting reading after 5 min, 10 min, 15 min, 30 min., etc., and found that the reading was very close to correct after only 15 min.
If you try to take a reading when the battery is connected to your RV, you will probably get an artificially low reading. It'll say 12.2 volts when it is really 12.5, for example.
