Battery Myth | Why is My 12 Volt Battery Reading as 13 Volts?
The actual resting voltage, or the voltage a battery will settle at 12-24 hours after being removed from the charger, is closer to 2.1 volts per cell, or about 6.4 volts for a 6v battery, and 12.7 volts for a 12v battery. These numbers assume 100% healthy cells, and may vary a bit lower for older batteries. Choose Your 12v Battery

Etorque battery voltage | DODGE RAM FORUM
good day gents…. I have a 2021 Ram with the 5.7 etorque and I notice the gauge for battery voltage only ever reads 13.5 or 13.6. On any vehicle I have ever owned, a good alternator will charge at up to 14 v after you start your engine and deplete battery. I know how to check battery voltage/...
Fluctuating battery voltage while driving
It will then set the voltage to match the battery voltage if it''s between 12.5 and 13.1 volts. If those conditions are not met it will enter the Charge Mode regulating the charging system between 13.9 to 15.5 volts. Yep that is why you see a step change! Reply Like

Easy explanation: RV Battery Voltage and State of Charge
The battery voltage is what a voltmeter reads, or how many of those four lights are illuminated on your display. The state of charge (SOC) is what the actual storage status of your battery is, 100% being fully charged and 0% being flat dead.. The reason there''s not a simple relationship between battery voltage and state of charge is that your RV system is constantly …
13.5V alternator when driving and idling | BobIsTheOilGuy
The control module enters Battery Sulfation Mode when the battery voltage is less than 13.2V for 45 minutes. Once in this mode, the generator battery control module will set a targeted output voltage between 13.9 and 15.5V for five minutes. The control module will then determine which mode to enter depending on voltage requirements.

What Voltage is Considered Bad for a Car Battery?
The same is true when measuring battery voltage to determine if a battery has gone bad. Fully-charged, most car batteries will measure at least 12.6 volts (~13.0-13.2V for OPTIMA YELLOWTOPs), but low voltage doesn''t necessarily equal a bad battery. Modern cars are very demanding from an electrical perspective, even when they''re not being used.
