Oh just STOP please.
Your original statement sounded like it is common place for a battery to self discharge at a rate of 40% per month.....and nothing could be farther from the truth.
A healthy battery that is not defective NEVER does that under normal conditions....NEVER.
You can make anything fail by abusing it. That proves nothing about it's normal performance.
It is a fact that most AGM batteries self-discharge at a much slower rate than most wet cell models, sometimes only 10% as fast but usually closer to 20%.
What this means in a practical sense is: A healthy, fully charged AGM battery can sit at 70 F or less for 4 to 6 months with no noticeable loss of power. Many (or most) wet cells would be down significantly in that same time period.
I quit.
