I cruised around on youtube while on the
trip out west . . . there's a bucket-load
of videos on a constellation of battery recovery
techniques claiming to recover batteries
ranging from 'just a bit tired' to 'retrieved
from salvage'.
A variety of techniques included replacing
electrolyte with Epsom salts, shocking
with 50-200 amp chargers and praying
over them with various versions of 'smart
chargers'.
Some demonstrations were marginally beneficial
(previously dead battery would now start an
engine) to one demo that claimed recovery to
80% of new. The most important thing missing
from ALL the demonstrations was DATA secured
by CAPACITY TESTING and LOAD TESTING.
Just as a hedge on bolstering my own understanding
for the current state of art and science in
battery maintenance, I wrote to the Battery
Guru at Battery University to inquire of
the latest.
Here is his reply:
Bob,
There was so much written of sulfation but no one has a simple
solution. We are working with military organizations to also
get a better insight into dormant lead acid batteries.
Universities are also working on sulfation reversal. It
is possible but not always practical. Please see
also: https://batteryuniversity.com/article/bu-804b-sulfation-and-how-to-prevent-it
Good luck and best wishes,

So . . . as of this point in time we can confidently
assert that there is yet no documented, repeatable
experiment supporting a notion that any products
or processes can claim great strides in battery
maintenance. Particularly batteries intended for
use in aircraft.
For us, marching orders are to USE and MAINTAIN
a battery so as to minimize irreversible damage
to the chemistry . . . and to swap out any
battery that does not meet minimal design goals
for continued airworthiness.
