Whats your usual voltage. Hemi etorque

[etbrown4]

On the evic I used to see 13.7 to 14.2 on the highway.
On the road today at 60 mpg, I saw 13.3 to 13.5. Don't understand the lower numbers.
Engine off I see 12.7.

Anyone know what it is supposed to be, and when it's too low?

It's too low when it won't start. Volts aren't really your concern but rather you should be measuring amps. You should do a load test with a unit like a carbon pyle tester to see if the battery is holding amps. If the test shows a low amperage you need to replace.

Mine is around 13.7 to 13.8 most of the time. Now and then I see it drop to 12.8 for a short while.
