    摘要: A low profile battery tester uses tapered apertures to located batteries in a thin tablet shaped body for testing. In one embodiment for conventional dry cells, the taper is in openings through the body, and in another embodiment for button cells the aperture does not extend through the body and the taper is in the plane of the body. A display of battery condition is provided by an array of light emitting diodes mostly driven by comparators, voltage references for the comparators being provided by a circuit including one of the light emitting diodes.
