  • Method and apparatus for automatic determination of lead-acid battery specific gravity
    Patent number: 7224168
    Abstract: In accordance with various embodiments, there is a method for determining the specific gravity of a battery. Various embodiments include the steps of applying an increasing current ramp to a battery and measuring a response voltage of the battery when the increasing current ramp is applied to the battery. When the current ramp reaches a predetermined current a decreasing current is supplied to the battery and the battery's voltage response is measured. The specific gravity of the battery can be determined based on the voltage response of the battery to the applied current ramp.
