A button cell, watch battery, or coin battery is a small battery made of a single electrochemical cell and shaped as a squat cylinder typically 5 to 25 mm (0.197 to 0.984 in) in diameter and 1 to 6 mm (0.039 to 0.236 in) high – resembling a button.
A "Harris for President" sign on a lectern. On July 21, 2024, Harris announced her intention to run for the Democratic nomination, [77] and the "Biden for President" campaign committee filed paperwork with the Federal Election Commission to change the name of the committee to "Harris for President".

The same physically interchangeable cell size or battery size may have widely different characteristics; physical interchangeability is not the sole factor in substituting a battery. [ 1 ] The full battery designation identifies not only the size, shape and terminal layout of the battery but also the chemistry (and therefore the voltage per ...
These button cells generally follow the same compact design. The bottom portion of the cell is the cathode, which consists of a graphite infused silver oxide. A plastic membrane separates this from an anode of powdered zinc dissolved in an alkaline electrolyte. An insulating gasket keeps the two contacts apart, facilitating the discharge of the ...
Mercury battery "РЦ-53М"(RTs-53M), Russian manufactured in 1989. A mercury battery (also called mercuric oxide battery, mercury cell, button cell, or Ruben-Mallory [1]) is a non-rechargeable electrochemical battery, a primary cell. Mercury batteries use a reaction between mercuric oxide and zinc electrodes in an alkaline electrolyte.
CR2032 lithium button cell battery Lithium 9 volt, AA, and AAA sizes. The top object is a battery of three lithium-manganese dioxide cells; the bottom two are lithium-iron disulfide cells and are compatible with 1.5-volt alkaline cells. Lithium metal batteries are primary batteries that have metallic lithium as an anode.
