HISTORY:

Leader (Voltmeter) Battery Tester

The Leader voltmeter battery tester was made in the USA around 1945.

It measured 2" in diameter by ⅝" thick (5.1 x 1.7 cm) and weighed 1.9 oz. (52 g).

The positive prong (bottom) was fixed to the battery tester, while the negative probe was on a short wire.

The meter had one scale that read up to 50 volts. This was enough to test the 45 volt "B" batteries used in

hearing aids in the early and mid 1940s, and the 30, 22½ and 15 volt "B" batteries of the late 1940s and early

1950s.

To test a battery's voltage, you touched the positive prong to the positive terminal of the battery, and

touched the negative lead (bottom) to the negative terminal of the battery.
