A FEW MONTHS AGO, I CAME OUT TO A DEAD BATTERY ON MY ENVOY. IT HAD BEEN SITTING UNUSED FOR ONLY 2 DAYS. I REPLACED THE BATTERY AND CONFIRMED THAT THE CHRAGING SYSTEM WAS WORRKING PROPERLY. THIS PAST WEEKEND I PARKED IT FRIDAY NIGHT AND ON MONDAY MORNING THE BATTERY WAS DEAD AGAIN. I ALWYS MONITOR MY GAUGES AND THEY NEVER INDICATED A CHARGING PROBLEM. ARE YOU AWARE OF ANY CHRONIC PROBLEM WITH ENVOY'S DRAINING THEIR BATTERIES???

Most autoparts stores will perform a battery/charging system test for free. They can also perform a "drain test" where the instrument tests for any unusual drains on the battery while engine is off.
Try this and see if there are any parasitic drains on the battery.
