I agree with everyone else's and your assessment that something is not right.  Get yourself an inexpensive Battery Tester like this one:

It's not a "real" load tester that a professional marine electrician would use.  However, I have one and was able to compare it's results side-by-side with a real load tester when I purchased my new batteries last year.  The results were very close (within 5% or less) to the "real" load test results.  Certainly close enough to see if one or more of your batteries has an issue and is compromising your whole battery bank.  I would get one of these ASAP and test each battery.

Also, you really can't trust the "% of Charge" on your battery monitor for much.  Here is a very long and detailed article as to why:
