What Should My Battery Gauge Read While Driving. Readings of 14 to 145 volts on the gauge when as a good sign. The teeth on the flywheel was broke in 2 places.
With the vehicle not running and the car sitting over night the battery voltage should be between 125 and 128 volts. You should see somewhere between 12 and 145 typically depending on whether or not the voltage regulator is telling it to charge. In our case with VRLA batteries Valve Regulated Lead Acid we have a typical open cell voltage of 21V with 6 cells which results in a battery that should sit at 126V with zero load fully charged.
What would make my voltage gauge read low when battery is good.
On startup 145 to 148 is probably normal. 10 Mar 9 2020. While driving today I noticed the battery bar gauge that I have on the dash looked a little lower than usual so I pulled the battery voltage screen up and it read 141. Why Shouldnt Battery Gauge Goes Up And Down.
