      Not a good or reliable number.  You may see things such as 13 V to 11.8 V.
       It will vary due to Time after a change and Temperature.  Check the
      Specific Gravity (SG) of the electrolyte.  And remember a aircraft battery
      has a higher SG than a auto battery AND you also need to check the
      Temperature when taking a reading.
      
      I know, I know, checking the electrolyte is a dirty PITA.  So, spend about
      $65 and get a digital Load Meter that will give you Volts, Internal
      Resistance and % of power in relation to the AH or CCA rating.

      A fully charged Gill G25 is ALWAYS ready for the garbage.

      Or get a sealed Concorde battery and solve the problem.
