This RS Pro alkaline battery is made with durable materials and the ability for a long shelf life completed with positive and negative spring terminal tags. Stay independent with high performance batterypower when using power hungry devices, such as remote controlled toys, computer equipment or LED flashlights. It was used in some early transistor radio amplifiers with a Class B output stage, allowing the loud speaker to be connected between the amplifier output and the battery center tap. Most sizes are uncommon today; however, the PP3 size (and to a lesser extent PP8, used in electric fencing, and PP9) is readily available. Introduced by Sanyo/Panasonic for use in portable power tools as higher-power and higher-capacity successor for 18650 cells.

For example, a CR123 battery is always LiMnO 2 ('Lithium') chemistry, in addition to its unique size. Many are also available with protection circuits that can increase their physical length; for example, an 18650 is around 65mm (2. The flat casing of the MN1203 contains multiple alkaline cells which together offer a higher capacity than the batteries fitted to more common household torches.

Often used in pairs instead of CR2032 for devices that require more than 3V, like blue/white LED flashlights. The MN1203 battery has a long life and provides an economical replacement for other battery models that offer less power. Used in small RF devices such as key fob-style garage door openers, wireless doorbells, and keyless entry systems where only infrequent pulse current is used. 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. Can be replaced with an AA cell using a plastic sabot (size adaptor), with proportional loss of capacity.

Because four cells in series produces a voltage range similar to 6 cells of Lead-acids and their fire-resistant properties, they can be used to replace a 12V lead acid car battery. 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 cell) and the number of cells in the battery. 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. Taller cells are assigned five-digit numbers, where the first two digits are the diameter in millimeters, followed by the last three digits indicating the height in tenths of millimeters. The terminal posts are threaded 8–32 ( Unified Thread Standard), insulated terminal nuts are normally provided, conical profile helical spring terminals are added for specific applications.LiFePO4 properties: long lasting (2000+ cycles), safer, more stable, good continuous/peak discharge rates (3C/10C), less energy dense.
