Energizer 3LR12 4.5 V Max Battery

Product Information

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. Same diameter as AA battery, used in small electronics, including pulse oximeters, as well as use in some computer models (such as most pre-Intel Macintosh models and some older IBM PC compatibles) as the CMOS battery. Stay independent with high performance batterypower when using power hungry devices, such as remote controlled toys, computer equipment or LED flashlights. Many are also available with protection circuits that can increase their physical length; for example, an 18650 is around 65mm (2. A rechargeable lithium-ion version is available in the same size and is interchangeable in some uses.

The increased dimensions may mean the cell will no longer fit in battery compartments intended for cells without such circuitry. The complete nomenclature for a battery specifies size, chemistry, terminal arrangement, and special characteristics. Cells less than one centimeter in height are assigned four-digit numbers, where the first two digits are the diameter in millimeters, while the last two digits are the height in tenths of millimeters.Commonly-used designation numbers indicate the physical dimensions of the cylindrical cell, as given in IEC standard 60086-1 for cylindrical primary cells. This cell type is used in many laptop computer batteries, cordless power tools, many electric cars, electric scooters, [207] most e-bikes, older portable powerbanks, electronic cigarettes, [208] [209] portable fans and LED flashlights.

This is a list of the sizes, shapes, and general characteristics of some common primary and secondary battery types in household, automotive and light industrial use.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.
