Battery Parasite Draw or Normal

I keep my trailer in a storage lot that does not provide electricity. I keep the battery disconnect switch in the off position. I will measure the voltage on the batteries and for example will show 12.5 volts. Go back two weeks later and they measure 12.4. Is this normal or do I have something drawing a little on the batteries.
