Forget about cleaning up temporarily and check for battery drain with car off as others have suggested. You might not get another battery under warranty as easily in a few weeks.
Depletion of the battery seems to do irrepairable damage if repeated. I hope your past battery was defective when first purchased. Otherwise you might be in for the same ride.
It really makes me upset to find one of my newer batteries discharged. I suspect part of it's overall capacity has been taken. I automatically know the lifespan is reduced big time from experience. We are not buying deep discharge cycle batteries for our cars.
As a consequence they really do not want this type of treatment. Fairly easy to verify if you have abnormal drain or not. Multipal threads in archives as well.
