[Mg-t] Removing Sulphation from Lead Acid Batteries

Removing Sulphation from Lead Acid Batteries

Whilst we are talking of Lead Acid batteries, there
is the  issue of sulphation, where lead sulphate
will build up over time and reduce the efficiency
of the cells until the cell fails.  Totally discharging
a battery and leaving for a time is a good way to
encourage this and ruin a battery in this way!

Tetrasodium EDTA is advised as a means of
"De-sulphating" a battery, either just adding it or
draining and soaking the battery in the stuff.

No doubt there are other reliable chemicals and
totally off the planet snake oils advertised to do
the same thing to greater or lesser result.

Again, Oh Electrically Inclined amongst us, what
benefits are to be had to both maintain a battery,
and to hopefully recover a failing battery by such
treatments?
