Come over for a beer or coffee anytime. We can talk batteries. For some reason my wife thinks the topic is boring

It is boring....
until the lights go out whilst cooking a nice dinner...
then it becomes drastically important,
where you anchored so can order chopper to drop in,:-)

This is quite a good technical document on batteries. Although much of refers to a specific gel battery (Sonnenschein.) it has general relevance.

If you scroll to page 28 there is a graph of cycle life verses DOD.

I used gel batts. at a time, very expensive- no good results good for boats due to NO-gasses, BUT when discharged extreme = polarity change and bugger important devices!!! good when new, dangerous when older
