• Where can I find a discount online for Extended battery. Rectangular battery with button on bottom and three contacts on back.

• Answer:

  This article lists the sizes of some common primary and interchangeable secondary battery types in household and light industrial use. The long history of disposable dry cells means that many different manufacturer-specific and national standards were used to designate sizes, long before international standards were reached. Technical standards for battery sizes and types are published by standards organizations such as International Electrotechnical Commission (IEC) and American National Standards Institute (ANSI). Popular sizes are still referred to by old standard or manufacturer designations, and some non-systematic designations have been included in current international standards due to wide use. The complete nomenclature for the battery will fully specify the size, chemistry, terminal arrangements and special characteristics of a battery. The same physically interchangeable cell size or battery size may have widely different characteristics; physical interchangeability is not the sole factor in substitution of batteries. A battery may consist of a single cell or two or more cells in a single package, such as the 2CR5 (two lithium cells) or a 4LR44 (four LR44 cells), or a 1604 9-volt battery which has six cells.

The relevant US standard is ANSI C18.1 Dry Cells and Batteries—Specifications; the standard is developed by a committee of the National Electronic Distributors Association (NEDA). Both standards have several parts covering general principles, physical specifications, safety, and differing types of primary and rechargeable cells. Designations by IEC and ANSI standards do not entirely agree, although harmonization is in progress. Manufacturers further have their own systematic identification of cell types, so cross-reference tables are useful to identify equivalent types from different manufacturers. [1] [edit] Battery chemistry The terminal voltage of a battery depends on the chemicals it uses, and not on its physical size. For example, primary (non-rechargeable) alkaline batteries have a nominal voltage of 1.5 volts. Rechargeable NiCd (nickel cadmium) and NiMH (nickel metal hydride) typically output 1.25 volts per cell. Devices intended for use with primary batteries may not operate properly with these cells, given the reduction in voltage. Formerly mercury batteries were made in button, cylindrical and oblong types but these are no longer available due to their environmental hazard. other source: http://steveswebhosting.com/shop_db/product_list.php?affiliate_id=5amp;category=5841&page=51&category=0 http://www.usbflashdrivestore.com/b-795.html
