      A 3/4 charge battery is 12.50 volts
      A discharge battery is 11.75 volts.
      A battery under a cranking load and it is reading less than 7 volts,it will be a recycled battery.

      Local auto parts stores will recharge, test your battery and the vehicle charging system with their mobile analyzer for free of charge.Give them a call.
