Default What should batt volts read before start

Should it be 12 or more? If Im at 11.5 do I think about a new battery?

Yes if its under 12 volts you have a bad battery. A 6 cell battery should have A min. of 2.2 volts per cell.

I would guess you have no problem. If you are reading the voltage from the DIC, I don't think it is real accurate as it is for reference only. I checked my every day driver for you which has a Optima red top and it read 11.8 volts on the DIC and checked with a accurate digital volt meter at the battery to be 12.1 volts. I will go on record that NO batt. will read 13.2 volts!!!

I agree, you need to check the voltage at the battery terminals with a good voltmeter.
I also see a lower reading on the DIC and just use that for reference. If you have at least 11.5 on the DIC, you should have at least 12 volts at the battery.

If your car is starting good, and there is no weird electricial things going on I'd say your good. Just my opinion.

While the car is running......With a good Meter, Read Voltage at the Battery and Compare to DIC.

I was at 10.5 volts the other day on the DIC, and it started you. It have been sitting for a week. Y2K OEM battery
