Patent ID: 8129954

Claim:
A system for charging and pulsating a battery having a positive terminal and a negative terminal comprising: a charger adapted to be electrically connected to said positive and said negative terminals of said battery, said charger including a charger controller; a pulsator adapted to be electrically connected to said positive and said negative terminals of said battery, said pulsator including a pulsator controller; and a voltage measuring circuit connected to said pulsator controller and adapted to be electrically connected to said positive and said negative terminals of said battery, and to measure a voltage across said positive and said negative terminals of said battery when so connected, said pulsator controller being programmed to receive signals from said voltage measuring circuit during a charging cycle to monitor said voltage across said positive and said negative terminals of said battery to detect when said charger is active, indicated by said voltage being above a pre-set threshold voltage, and inactive, indicated by said voltage being below said pre-set threshold voltage, and activate said pulsator only when said measured voltage drops below said preset threshold voltage indicative of said charger completing a charging cycle and being inactive.
