i would think it would work, but would be hesitant to try it on expensive batteries unless i had no other way of perserving them.
and i can see the possibility of such a need arrising myself, such as
you get a killer deal on a set of batteries but cannot put them into service for a number of years, under that circumstance
i might give it a try after first calling a manufacture such as rolls/surrette or trojan to get some input on how to do it properly.
i remember years ago we used to get our truck batteries shipped dry, they had plastic plugs down in the cap holes that you pryed out
and then filled with electrolyte.
i would expect one would need some form of plastic plug that fits nice and tight, and maybe purge the cells with nitrogen if
the manufacture supported that method or with whatever inert gas they recommended.
iirc you need to get the air out, effectively removing the oxygen so the plates don't oxidize over time.
seems to me it ought to work
just be sure to fully charge the cell, drain the electolyte and flush them with distilled and demineralized water
then purge with an appropriate inert gas and plug the cells. sure seems like it ought to work.
hmmm,, interesting
i have put off buying batteries over the last few years knowing that it will be a few more years before i would be putting them
into service, i surely would not want wet cells stored long term (years) and figured i would go the dry cell batteries for extended storage.
i wonder why it wouldn't work?
good question
