Battery charger having current increasing circuit

A battery charger adapted to increase a charge current applied to at least one battery from a predetermined supply voltage, comprising:

• a power transformer coupled to an AC voltage source for generating the predetermined supply voltage;
• and
• a charging circuit electrically connected to said transformer and including a first capacitor and a second capacitor AC coupled to the first capacitor, said charging circuit being adapted to apply the charge current from said transformer to the at least one battery through said first capacitor during a first half of a charging cycle, and store the charge current from said supply voltage generating means in said second capacitor during a second half of said charging cycle and apply the charge current to the at least one battery during the first half of said charging cycle to increase the charge current applied to the at least one battery during said first half of said charging cycle;
• said first capacitor being operatively connected in said charging circuit to block DC current to said supply voltage generating means when a short occurs across an output of said battery charger during said first half of said charging cycle, and said second capacitor being operatively connected in said charging circuit to block said DC current to said supply voltage generating means when a short occurs across an output of said battery charger during said second half of said charging cycle.
