Epsom Salt raises voltage. this can help to stop sulfation.
Epsom salt raises conductivity and increases the amps a battery can provide.
Epsom salt does not desulfate a battery over a short time period.
Epsom salt does not increase AH/capacity over a short time period.
and lastly Epsom salt seems to give the battery an overcharge capability. this is far more evident in my video “DIY opening a car battery and repairing with epsom salt” when i discover the battery goes from 11v to over 12v after i short out the terminals.
in other words charging and discharging the battery quickly within a short amount of time seems to raise capacity temporarily.
