Years ago when I worked in the "trade" there was a little black box for testing cells Carbon-Zinc Alkaline etc. Does anyone have an idea of the load resistors used for the various size cells? D, C, AA, AAA. at least. With all the "stuff" that is using such and an open ckt. test that always reads very close to the new voltage, I want to build a simple tester so even the wife can check the "batteries" in the TV remote etc. :-) ...Lew Hartswick...
