BT-1 Heathkit Battery Tester

The model BT-1 is as special battery testing device that actually "loads" the battery (draws current from it) while it is being tested. Weak batteries often test "good" with an ordinary voltmeter, but the built-in load resistenace of the BT-1 automatically draws enough current from the battery to reveal its true condition. Simple to operate, and no complicated meter readings to interpret.

To use the model BT-1 just set the voltage selector, connect the leads to the battery, and read the condition of the battery in the three-color "good-weak-replace" scale. Test batteries in a way your customers can understand and stimulate battery sales. Ideal for testing dry cell hearing aid, flashlight, portable radio, and model airplane batteries. Provides test ranges of 0-15 volts and 0-180 volts. A slide switch provides for either 10 ma or 100 ma load, depending on whether you're testing an A or B battery. Not only determines when battery is completely exhausted, but makes it possible to anticipate failure by noting weak condition.
