Handheld tester for starting/charging systems

A hand-held, portable battery tester for testing a battery via connecting to battery terminals of the battery, comprising:

• a. an electronic battery test circuit, said test circuit performing at least one test on the battery by applying an AC load current to the battery and analyzing a voltage generated by the load current applied to the battery;
• b. a hand-held, portable enclosure housing said electronic test circuit;
• c. a housing connector providing a plurality of electrical connections, said housing connector being associated with said housing and said plurality of electrical connections being in circuit communication with said electronic test circuit;
• and
• d. a removable test cable for removably placing said electronic test circuit in circuit communication with the battery, said test cable:
• i. providing a plurality of electrical conductors;
• ii. having a removable cable connector at one end of conductors of said plurality of electrical conductors for connection to said housing connector to place conductors of said plurality of electrical conductors in circuit communication with connections of said plurality of electrical connections;
• and
• iii. having a plurality of battery clips at other ends of conductors of said plurality of electrical conductors for connection to the battery terminals;
• and
• wherein said removable cable connector, said plurality of electrical conductors, and said plurality of battery clips cooperate to provide a Kelvin connection from said electronic battery test circuit to the battery, to pass the AC load current through the battery via the battery terminals and to communicate voltage generated across the battery terminals by the AC load current back to the electronic battery test circuit, when said removable cable connector is connected to said housing connector and said battery clips are connected to the battery terminals.

A hand-held, portable tester for testing a starter/charger system of an internal combustion engine via connecting to battery terminals of a battery of the starter/charger system, comprising:

• a. an electronic test circuit, said test circuit capable of performing at least one test on the starting/charging system via connecting to the battery terminals;
• b. a hand-held, portable enclosure housing said electronic test circuit;
• and
• c. a housing connector providing a plurality of electrical connections, said housing connector being associated with said housing and said plurality of electrical connections being in circuit communication with said electronic test circuit;
• and
• d. a removable test cable for removably placing said electronic test circuit in circuit communication with the battery, said test cable:
• i. providing a plurality of electrical conductors;
• ii. having a removable cable connector at one end of conductors of said plurality of electrical conductors for connection to said housing connector to place conductors of said plurality of electrical conductors in circuit communication with connections of said plurality of electrical connections;
• and
• iii. having a plurality of battery clips at other ends of conductors of said plurality of electrical conductors for connection to the battery terminals;
• and
• wherein said removable cable connector, said plurality of electrical conductors, and said plurality of battery clips cooperate to provide a Kelvin connection from said electronic battery test circuit to the battery when said removable cable connector is connected to said housing connector and said battery clips are connected to the battery terminals.
