A fresh alkaline zinc battery can have an open-circuit voltage of 1.6 volts, but an iron-disulfide battery with an open-circuit voltage below 1.7 volts is entirely discharged.
A fully charged battery, without a drain or load, after the surface charge has dissipated, is 12.63 volts for a 12 volt battery. Other states of charge are: 12.60 volts = 93% charged 12.55 volts = 89% charged 12.50 volts = 85% charged 12.45 volts = 80 % charged 12.18 volts = 50 % charged.reparing your batteries for winter. Advantages and Disadvantages of using two 12 volt batteries connected in parallel or two 6 volt batteries connected in series. Testing the battery. 1  Cycle the battery lightly (20% or less depth of discharge) the first few cycles.
