affordable battery tester
I understand percentage better than volts. Is there a battery tester that gives you percentage to help me understand the available charge of my batteries on Fiver.

I killed my first set of RV batteries relying on the idiot lights and voltage chart. X2 on the battery monitor counting amp-hours! My second set of (Costco) batteries is in excellent shape after five years.
Unfortunately none of our vehicles have battery monitors so I do use the voltage method for the engine batteries - very carefully. I disconnect the battery in the evening and check the voltage the next morning. I think the chart is fairly accurate that way. Although the RV batteries are still well over 12.7 volts after being disconnected for a month.
