What kind of unreasonable service life do you get if you use the full
capacity, and at $20 each do you care if you use it up faster? Unless you
can count the number of cycles on your fingers that may be the simplest
and most cost effective way to go, although of course I may be overlooking
something important.

I have found that using 60% or perhaps 70% does not seem to limit their life
noticeably. What does kill them is to charge them too fast, or most
importantly, leaving them sitting around in a discharged state. Doing that one
time could be the end of them.

The better question than asking how much more quickly a higher discharge kills
them for the price, is to ask why not buy an extra one, or two.

Larger gell cells are also available, but I'm not sure where the economics of
buying more small ones versus buying a single larger one come into play.
