Weak Automotive Battery... need some specification type info?
I'm specifically looking for what voltages you would read and/or what amperage you would read when you test the battery.
The reason I ask this is that I went in for a State Inspection the other day and the "commercial" facility tested my battery and told me it was weak and should be replaced. I suspect they were trying to sell me a battery, but I would like to know the true data so I can do the voltage/amperage tests on the battery myself.
Thanks for any help you can give.
