How many volts should a Jeep battery have?
12.5 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.
Is 11.9 battery voltage good?
11.9v indicates the battery is completely discharged. Anything under 12.2v means the battery is in a state of discharge, and a healthy battery should show 12.6v in a static state. Yours needs to be replaced. 11.9v indicates the battery is completely discharged.
What should the voltage be on a jeep Charger?
Charging voltage should be pretty close to 14 volts with the engine running and no headlights or other heavy loads. Even with headlights on, it should be 13.8 volts. ? A dealer actually claims 15 is normal? Have you got an alternator/electrical shop in the area that could offer better advice?
What should the battery voltage be when the car is running?
The voltage, when the engine is running, should be in the range of 13.5-14.7 volts. When your car is running the cars alternator is charging the battery, this is why you should see a higher voltage. If you’re readings are significantly higher or lower than these then it would indicate a fault with the battery and/or the alternator.
How long does a Jeep Grand Cherokee battery last?
OEM AGM batteries, generally have a longer life than replacement batteries. If an OEM battery has a 3-year warranty you can reasonably expect to get six or seven years of life.
What’s the normal charge rate for a jeep?
Fully charged after sitting for an hour or two it should read 2.1v/cell or 12.6v. The maximum charge rate is 2.45v/cell or 14.8v. For maximum life I prefer a 13.6v-13.8v charge rate. I’m thinking my early build ’14 doesn’t show tenths, so it may be rounding 14.8 up to 15. I only get that when cruising the interstate. Does this sound plausible?
