ABSTRACT:
A pulsed current battery charging method functions to improve battery capacity characteristics of a liquid electrolyte electrical storage battery and prolong battery useful life. Pulses of charging current are applied optionally concurrent with conventional charging current. The pulse amplitude is of significant magnitude in relation to conventional small, finishing rate or trickle charge charging currents. Pulse amplitude, duration and pulse repetition rate are controllable. Apparatus designed to carry out this method includes power supply means, pulse current generating means and optional control means.
