You have an electrical load that is not turning off in your vehicle. Could be something as little as your dome light or the light or the light under the hood. That's why when you shut it off its draining your battery. Try and find the source.

HOW 'BOUT CHECKING OUT "MY ANSWER" IN THIS POST....EZ FOR YOU TOO GO THERE...THAN ME PECK IT ALL OUT AGAIN!

http://www.2carpros.com/questions/2002-acura-mdx-battery-always-dead

JUST TO ADD A LITTLE MORE INFO TO IT

CONSIDER THIS.........IF YOU DON'T FIND IT USING THE INFO WITHIN THE LINK

OVER TIME, I HAVE LEARNED, IN SEVERAL CASES, THAT A "BAD ALTERNATOR" HAS BEEN THE PROBLEM. WHILE CHECKING FOR THIS POSSIBILITY. THE "PARASITIC DRAIN" NORMALLY MADE THE VEHICLES"UN-START-ABLE" EACH MORNING---THEY COULD BE RECHARGED OF JUMPED OFF AND WOULD RUN.

THE ACTUAL "TEST" FOR THIS (FOR ME) HAS BEEN TO PARK THE FULLY CHARGED VEHICLE, THEN REMOVE ALL OF THE WIRES FROM THE ALTERNATOR AND INSURE NONE ARE TOUCHING ANYTHING ELSE. LET IT SIT OVERNIGHT OR LONGER. IN MOST CASES, I COULD START THE CAR WITHOUT EVEN RECONNECTING THE ALTERNATOR, THUS PROVING THE ALTERNATOR WAS THE DRAIN, SIMPLY BECAUSE THE BATTERY "SURVIVED" THE NIGHT, AND REMAINED CHARGED.

THIS IS SOMETHING TO TRY BEFORE SNATCHING IT OFF AND HAVING IT TESTED AT A POPULAR AUTO PARTS STORE, OR NEEDLESSLY BUYING A NEW ONE.

NEED MORE INFO.......JUST ASK!

RETURN WITH GOOD NEWS!
