2003 Honda element parasitic battery drain!

Just because the battery is only one month old does not mean that the problem might not mean that the battery isn’t defective. I bought a new battery once that didn’t last a weekend. I diagnosed it by disconnecting the negative cable on the battery, charging it up with the battery charger and measued the voltage which about 12.6. I let the battery sit for 6 hours and the voltage was about 10 volts. I would begin by having the battery load tested.
