1.5~2 month would be about right, had that quite a few time. 2 weeks sounds quite short for a '19 batt though.. most likely parasitic or faulty cell.
Few tutorials on how to debug parasitic drain(s) on YT, e.g. using a dmm and pulling fuses. I'd rule that out before coming to a conclusion that the battery is faulty and needs changing.
Far more boxstech savvy members here may know the exact constant drain figure but I believe 50~100mA drain is considered normal when parked/locked.
