I have not measured drain current on mine but I have 6 years old 88Ah 730CCA battery which according to conductance tester have 61% capacity left and 630CCA and it recommends to replace the battery. If car is left alone for 2 weeks battery voltage will drop from 12.6V to 12.2V but it does start just fine at this voltage. I have had battery to drop to 11.5V in the past and it still started car but engine was barely turning over.
