just because you for the moment your testing see this leakage of 2 MA does not mean it is constantly at this level...disconnect the battery when the engine is off and see if the battery holds full charge...

many have had these leakages occur randomly..

also as others have stated no charger / alternator will output more the 14 volts constantly because if so the battery will get cooked..

once the battery is at normal temp the charging voltage on a charged battery would be 13.75 max....
