That's not 12 amps,that's 12 volts,which means the system isn't charging
Measure the voltage across the battery terminals,if its charging properly,it will be between 13.8 and 14.7 volts,anything less and its not charging.
Suspect then a faulty alternator or wiring problem.
and have the battery properly recharged and tested too,a low battery will not give you a correct charging reading and a faulty alternator can take its toll on a battery.
