Research studies show ETP minimizes the accumulation and crystallization of sulphate
ions. These ions (SO4), existing in the electrolyte (dilute sulfuric acid), become
attached to the electrodes when discharged (the specific gravity decreases) and
return to the solution when charged (the specific gravity increases).This is part
of normal operations.
However, as this cycle is repeated, sulphate ions that are not actually involved
in charging and discharging accumulate at the electrodes and crystallize, thus preventing
full charging and discharging.
The product of this accumulation and crystallization is called “sulphation.”
This is what causes battery performance to first deteriorate and then die -- years
earlier than necessary.
Scientific evidence as well as field tests were run on trucks, fork lifts, buses,
and golf cars, etc. has shown that ETP extends battery life by preventing sulphation.
