Is the cathode the steel case, or is it the Oxide (e.g. Mercury Oxide)?

A watch battery or button cell is a small form-factor battery designed for use in wrist watches, pocket calculators, hearing aids, and similar compact portable electronics products. Watch batteries are usually a single cell with nominal voltages between 1.5 and 3 V. Common anode materials are zinc or lithium, common cathode materials are manganese dioxide, silver oxide, carbon monofluoride or copper oxide. The cylindrical surface of these types of batteries is part of the positive (+) terminal.

the internal floor section or quantity of the battery do not make certain the voltage, they merely make certain the cost saved (or maybe that varies once you study categories of batteries). that's the chemical skill and absence of inner resistance that governs voltage. via the way, a sparkling AAA battery is a million.fifty 4 volts. It does not get right down to a million.2 volts till that's fairly lots ineffective.
