Abstract
Abstract An automatic discharging device is provided and consists of at least one light emitting diode and at least one resistor within at least one electrical wiring discharge circuit in a housing. An alligator clip is connected to each end of the at least one electrical wiring discharge circuit extending from the housing to connect to the terminals of a battery. The at least one light emitting diode will go out when the at least one resistor reaches its desired load indicating that the battery has reached its desired discharged state.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
177 words
An automatic discharging device comprising: a) a housing; b) a first rapid electrical wiring discharge circuit within said housing; c) a second slower electrical wiring discharge circuit connected to said first electrical wiring discharge circuit within said housing; d) a first light emitting diode within said first rapid electrical wiring discharge circuit; e) a first resistor within said first rapid electrical wiring discharge circuit; f) a second light emitting diode within said second slower electrical wiring discharge circuit; g) a second resistor within said second slower electrical wiring discharge circuit; h) a pair of alligator slips, each said alligator clip connected to one end of both said first rapid and said second slower electrical wiring discharge circuit extending from said housing to connect to the terminals of a battery, whereby said first light emitting diode will go out when said first resistor reaches its desired load, and said second light emitting diode will go out when said second resistor reaches it desired load indicating that the battery went through two discharging stages to its desired discharged state.
Claim 2
Dependent Claim
177 words
An automatic discharging device comprising: a) a housing; b) a first rapid electrical wiring discharge circuit within said housing; c) a second slower electrical wiring discharge circuit connected to said first electrical wiring discharge circuit within said housing; d) a first light emitting diode within said first rapid electrical wiring discharge circuit; e) a first resistor within said first rapid electrical wiring discharge circuit; f) a second light emitting diode within said second slower electrical wiring discharge circuit; g) a second resistor within said second slower electrical wiring discharge circuit; h) a pair of alligator slips, each said alligator clip connected to one end of both said first rapid and said second slower electrical wiring discharge circuit extending from said housing to connect to the terminals of a battery, whereby said first light emitting diode will go out when said first resistor reaches its desired load, and said second light emitting diode will go out when said second resistor reaches it desired load indicating that the battery went through two discharging stages to its desired discharged state.
Claim 3
Dependent Claim
72 words
An automatic discharging device as recited in claim 1, further including: a) a third still slower electrical wiring discharge circuit connected to both said first rapid and said second slower electrical wiring discharge circuits; b) a third light emitting diode within said third still slower electrical wiring discharge circuit which will go on when said second light emitting diode goes out, visually indicating that the battery has reached its desired discharged state.
Claim 4
Dependent Claim
78 words
An automatic discharging device as recited in claim 6, futher including: a) a red lens in said housing over said first light emitting diode; b) a green lens in said housing over said second light emitting diode; and c) a yellow lens in said housing over said third light emitting diode so that a person using said device can see the various colors when said light emitting diodes are on to indicate the various stages of battery discharge.
