1. A method of charging a lead-acid battery utilizing a charging device comprising:
- providing the lead-acid battery with a first substantially constant current of approximately 30.0 amps;
determining if a voltage of the lead-acid battery reaches approximately 15.6 volts;
terminating application of the first current if the lead-acid battery is not less than 15.6 volts, and not later than approximately 3.0 hours have elapsed;
providing the lead-acid battery with a first substantially constant voltage of approximately 14.8 volts at an initial current of no more than approximately 30.0 amps;
determining if the current of the lead-acid battery is greater than approximately 1.0 amps;
terminating application of the first voltage if the current of the lead-acid battery is not greater than 1.0 amps, and not later than approximately 4.0 hours have elapsed;
providing the lead-acid battery with a second substantially constant current of approximately 3.0 amps;
determining if the voltage of the lead-acid battery reaches approximately 17.5 volts;
terminating application of the second current if the lead-acid battery is not less than 17.5 volts, and not later than approximately 1.0 hours have elapsed; and
providing the lead-acid battery with a second substantially constant voltage of approximately 13.8 volts at a current of no more than approximately 1.0 amps.

Abstract
An improved battery charging method is usable by a battery charger to charge a battery. The charging method may include an optional desulfation process, a first constant current process, a constant voltage process, a second constant current process and a float charge process. The charging method preferably improves various charge and usage characteristics of the battery through a single or continued use of the battery charger utilizing the charging method.
