Lithium-ion Batteries
The lithium-ion family on this site covers three branches: coin cells, cylindrical cells, and battery packs. Coin cells divide into CR manganese-dioxide types, BR poly-carbonmonofluoride types, and VL and ML rechargeable coin types. Cylindrical cells cover the CR2, CR123A, 2CR5, and CR-P2 types and the 18650, 21700, and 22700 rechargeable series.
Every specification table in this family is brand-owner catalog data, labeled with the brand owner on the page where it appears. The CR and BR tables are Panasonic catalog data, carried on the distributor's brand page. Nothing in this family is presented as a cell manufactured by Unitek.
Battery packs in this family are described by listing strings only. A pack listing string names a configuration as listed; it is never expanded into a specification table on this site, and no pack figure should be read off a listing string.
For a named cell or pack, use the inquiry form and ask for the datasheet, the variant, and the ordering steps. Confirm the figures, variants, documentation, and ordering steps for the named item before ordering.
