  9. Battery regenerator - Wikipedia

    en.wikipedia.org/wiki/Battery_regenerator

    A sulfated battery has higher electrical resistance than an unsulfated battery of identical construction. As related by Ohm's law, current is the ratio of voltage to resistance, so a sulfated battery will have lower current flow. As the charging process continues, such a battery will reach the charger's preset cut-off more rapidly, long before ...
