What should Jeep Wrangler battery voltage be?
Touch the black to the ground, red to the positive, and the battery shows 12.57 volts. With the Jeep off a battery should show roughly 12.5 volts. When cranking the motor, the battery should hold a voltage of at least 10.5, nothing less. If it is less your battery is run down, dead, bad, or it may be a bad starter.
What should the voltage be on a jeep EVIC?
The dealership says that Chrysler engineers were the ones that said 15 volts was acceptable. Everything is fine. My EVIC screen toggles between 14 and 15 volts at idle. I took a battery voltage measurement also at idle and I got 14.6 volts.
What does it mean when battery voltage is 12.2v?
Measuring the voltage shortly after the engine has been running can give you a higher, misleading, reading. If the voltage is below 12.6v it indicates that the battery isnt fully charged or has a fault. The voltage doesn’t have to differ much from 12.6v for it to indicate a discharged battery. At 12.2v the battery is in effect 50% discharged.
Why does my Jeep have higher than normal voltage?
An open diode in the alternator can result in higher than normal readings as you are really getting pulsating DC on top of the nominal 12.5 volts, but batteries make pretty good filter caps at smoothing that out… and yours has allegedly been replaced already. RatShack has nice little DVMs that aren’t too shabby, cheap.
What happens to a car battery when it drops to 12.4 volts?
When a car drops, for instance, from 12.6 to 12.0, there will be 75% difference. Its power drops from 100% to 25%. At 12.4 volts, a car battery is 75% charged while at 12.2 volts its 50% charged.

Is the 12VDC battery reading 16v or lower?
-40 might get that high depending on the configuration of the CC,, but it should be lower now. Re: 12vdc battery reading 16v..?
What should the voltage be on a 12 volt battery?
A 12-volt battery will read 12.6 volts or higher after charge; a 6-volt battery will read 6.4 volts or higher after charge. Make sure the battery terminals are free of corrosion before testing. Batteries must be at 100% voltage before a load test can be applied.
What is the float voltage of a 12VDC battery?
Re: 12vdc battery reading 16v..? In the citation I note,,, the float and absorb voltages are at 25c/77f with a voltage differential of .005v/degree C. So your chart gives a float voltage of 13.7.
