I'm not talking about in use, it's during storage.

They don't specify type of battery. They are talking about irregular sulfate buildup during early stages of discharge. I'm trying to find out if the statement has any validity. I guess your tongue-in-cheek reply indicates your confidence in the assertion.

15 to 20% seems like a lot. Battery University says estimated self-discharge of a FLA is 5% a month (greater at higher temps). So that's 3 or 4 months?
Here's an example of what I'm seeing every day.
Batteries currently on float at 13.5 - 13.7 volts
Panels producing .5 amp with .2 going to the batteries and .3 going to phantom loads
Average daily production 8 - 9 amp hrs.
5 - 10 min. in absorption
10 - 11 hrs. in float
How do others that have solar handle RV storage?
