New battery chemistries have strained older naming conventions. Rechargeable NiCd and NiMH typically output 1.25 V per cell. Some devices may not operate properly with these cells, given the 16% reduction in voltage, but most modern ones handle them well. Conversely, lithium-ion rechargeable batteries output 3.7 V per cell, 23% higher than a pair of alkaline cells (3 V), which they are often designed to replace. Non-rechargeable lithium-chemistry batteries, which provide exceptionally high energy density, produce about 1.5 V per cell and are thus similar to alkaline batteries.
Battery naming is further confused by the practice of manufacturers that assign novel names and numbers to their batteries, disregarding common, colloquial, IEC, and ANSI naming conventions (see LR44 battery as an example). Often this is done to steer customers towards a specific brand, and away from competing or generic brands, by obfuscating the common name. For example, if a remote control needs a new battery and the battery compartment has the label, "Replace with CX472 type battery," many customers will buy that specific brand, not realizing that this is simply a brand name for a common type of battery. In this article, brand-specific names have been purposefully omitted to avoid confusion.
On the other hand, with obscure battery types, the name of a specific brand will sometimes become the most common name for that battery type, as other manufacturers copy or modify the name so that customers recognize it.
The following table is a list of battery sizes which are currently available in modern society. Note that there were other sizes other than those listed in this table which are no longer available due to either a decline in popularity or changing technological needs. Batteries for obsolete portable vacuum tubes devices for example, are not listed. A table of older, obsolete, and uncommon-availability batteries types and sizes can be found below this table.
