Introduced by Sanyo/Panasonic for use in portable power tools as higher-power and higher-capacity successor for 18650 cells.

In the following table, sizes are shown for the silver-oxide IEC number; types and capacity are identified as "(L)" for alkaline, "(M)" for mercury (no longer manufactured), and "(S)" for silver-oxide. The easy to use control system has one push button to go, as well as an easy to read display showing the speed and battery gauges. The first two digits are the nominal diameter of the cell in millimetres, and the two following digits are generally the height in millimeters, with the fifth digit indicating cylindrical shape.

Typical 20th century uses for this high capacity dry cell named for its 6-inch height include school science experiments, and starting glow plug model engines and in antique equipment.

This dry cell is commonly used in the UK for remote level crossing telephone handsets, where solar cells and rechargeable batteries have not been specified or retrofitted.This size is sometimes used in devices that can take either one 26650 or three AAA cells in series in a cylindrical 3-cell battery carrier. lithium-ion battery which can be disconnected and transported separately (the intuitive, easy to grip two peg design allows easy mounting without using any tools). Commonly-used designation numbers indicate the physical dimensions of the cylindrical cell, as given in IEC standard 60086-1 for cylindrical primary cells.
