Battery conditioner and charger
First Claim
1. A battery conditioner and charger for use with a lead-acid type of storage battery, comprising:
- (a) a power supply that is adapted to supply a first DC voltage to a storage battery and wherein said first DC voltage includes a peak voltage that is approximately equal to or greater than double the normal voltage output of said storage battery; and
(b) means for regulating the application of said first DC voltage to said battery, wherein said means for regulating includes means for limiting an average voltage through said battery, wherein said means for limiting an average voltage includes a pulse width modulator that is adapted to supply to said battery a pulsed DC waveform of said first DC voltage, wherein said pulsed DC waveform includes a repetition rate that is equal to or greater than 120 pulses per second and equal to or less than 400 pulses per second.

Abstract
An apparatus for charging either a normal or a sulfated type of a storage battery includes a first charging stage, a second charging stage, and a final third charging stage. The first charging stage applies a pulsed voltage with a high peak and average voltage to the battery until an average current of about 12 amperes is attained, at which time transition into the second charging stage occurs. A pulse width modulator reduces the average voltage and average current to a safe level and continue to charge the battery for about 20 minutes. At that time transition into the third charging stage occurs wherein a low ripple 14.8 VDC steady state current-limited voltage is applied to the battery for a second duration of about four hours, after which charging is complete and the apparatus shuts itself off.
