Welcome to our site, Joe !!!
As pointed above, your battery should measure 12.6~12.8 volts with engine and lights off.
Very important: While cranking to start, the voltage of a healthy battery will not drop below 10 volts.
If your battery as good as new, one of our FI experts will post here soon to further help you.
If you read a post from @
