Abstract

An electronic battery tester for testing a storage battery provides a test output indicative of a condition of the battery. Electronic measurement circuitry provides a measurement output related to a condition of the battery. The battery condition is determined based upon one or more responses to one or more queries provided to an operator. The responses are used to determine battery type.

Claims

2-55. -55. (canceled)

56. A method of performing a battery test using an electronic battery tester, comprising:

connecting the electronic battery tester to a storage battery;

receiving a query from the electronic battery tester regarding an observable physical characteristic of the battery;

providing the electronic battery tester a response to the query related to the observerable physical characteristic; and

receiving a battery test result from the electronic battery tester which is related to a measurement performed on the battery by the electronic battery tester and upon the response to the query.

57. The method of claim 56 wherein receiving a query comprises observing a display.

58. The method of claim 56 including retrieving the query from a memory.

59. The method of claim 56 wherein the measurement comprises a measurement of a dynamic parameter.

60. The method of claim 56 including coupling to the battery with Kelvin connection.

61. The method of claim 56 wherein the measurement is a function of an applied forcing function having a time varying signal.

62. The method of claim 56 including receiving a plurality of queries.

63. The method of claim 56 wherein the query relates to observable physical construction of the battery.

64. The method of claim 56 wherein the query relates to a shape of the battery.

65. The method of claim 56 wherein the query relates to a color of the battery.

66. The method of claim 56 wherein the query relates to caps on the battery.

67. The method of claim 56 wherein the query relates to a tube connected to the battery.

68. The method of claim 56 wherein the query relates to a visible liquid level of the battery.

69. The method of claim 56 wherein the query relates to a “

magic eye”

on the battery.

70. The method of claim 56 wherein the query relates to the brand label on the battery.

71. The method of claim 56 wherein the query relates to a battery type.

72. The method of claim 71 wherein the battery type comprises sealed lead acid.

73. The method of claim 71 wherein the battery type comprises vented lead acid.

74. The method of claim 71 wherein the battery type comprises spiral.

75. The method of claim 71 wherein the battery type comprises deep cycle.

76. The method of claim 71 wherein the battery type comprises an electrolyte gelatin.

77. The method of claim 71 wherein the battery type comprises an absorbed glass matt.

78. The method of claim 71 wherein the battery type comprises starting, lighting, ignition battery.

79. The method of claim 71 wherein the battery type comprises sealed flooded.

80. The method of claim 71 wherein the battery type comprises antimony.

81. The method of claim 71 wherein the battery type comprises hybrid.

82. The method of claim 56 wherein providing a responses comprises touching a desired response on a screen.

83. The method of claim 56 wherein providing a response comprises scrolling through a set of responses.

84. The method of claim 56 wherein providing a response comprises pressing a button.
