Sulfation is the #1 killer of batteries!
Scientific basis for de-sulphation process/circuitry
Every element known to man has a magnetic moment at a resonant frequency ie. a point at which the chemical bonds that hold the molecules together to form a crystal can be broken. Sulphation, the number one cause of early battery failure, is simply crystals of lead sulphate (PbS04) which have formed on the lead storage plates in a lead-acid type battery.
When a battery is improperly charged (over/under) or allowed to self discharge as occurs during storage/non-use, these crystals build up on the battery's storage plates preventing the battery from ever being fully charged and therefore able to deliver their full power/capacity.
