What should the voltage be on a fully-charged Gill 25 battery?

Scott:



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.
