## At what voltage is a 12v battery dead?

For a 12 volt, leadacid battery, the voltage measured between these two points should be between 11 and 13 volts. The closer the voltage is to 13 volts, the closer the battery is to being fully charged. The closer the voltage is to 11 volts, the closer the battery is to being “dead”.

## What voltage is too low for car battery?
