1.5V R20 UM1 Heavy Duty D Battery
The U.S. military designation for this battery has been BA-30 since sometime before World War II. A D battery (D cell or IEC A D battery (D cell or R20) is a standardized size of a dry cell A D battery (D cell or R20) is a standardized size of a. A D cell (D cell or R20) is a standardized size of a. A D cell is cylindrical with an electrical contact at each end; the positive end has a nub or bump. cells are typically used in high current drain applications, such as in large flashlights, radio receivers, and transmitters, and other devices that require an extended running time.

Super heavy duty 6f22 PP3 zinc carbon 9v battery
The nine-volt PP3-size battery is commonly available in primary zinc-carbon Designations for this format include NEDA 1604 and IEC 6F22 (for zinc-carbon) or MN1604 6LR61 (for alkaline). The size, regardless of chemistry, is commonly designated PP3—a designation originally reserved solely for carbon-zinc, or in some countries, E or E-block.[3] A range of PP batteries was produced in the past, with voltages of 4.5, 6, and 9 volts and different capacities; the larger 9-volt PP6, PP7, and PP9 are still available. A few other 9-volt battery sizes are available: A10 and A29.

1.5V R03 UM4 Heavy Duty AAA Battery
AAA batteries are most often used in small electronic devices, such as TV remote controls, MP3 players and digital cameras. Devices that require the same voltage, but have a higher current draw, are often designed to use larger batteries such as the AA battery type. AA batteries have about three times the capacity of AAA batteries. With the increasing efficiency and miniaturization of modern electronics, many devices that previously were designed for AA batteries (remote controls, cordless computer mice and keyboards, etc.)

1.5V R14 UM2 Heavy Duty C Battery
A C battery measures 50 mm (1.97 in) length and 26.2 mm (1.03 in) diameter.The C battery (C size battery or R14 battery) is a standard size of dry cell battery typically used in medium-drain applications such as toys, flashlights, and musical instruments.Like the D battery, the C battery size has been standardized since the 1920s.

1.5V R6 UM3 Heavy Duty AA Battery
The AA battery (or double-A battery) is a standard size single cell cylindrical dry battery. The IEC 60086 system calls the size R6, and ANSI C18 calls it 15. It is named UM-3 by JIS of Japan.Primary (non-rechargeable) zinc–carbon (dry cell) AA batteries have around 400–900 milliampere hours capacity, with measured capacity highly dependent on test conditions, duty cycle, and cut-off voltage. Zinc–carbon batteries are usually marketed as “general purpose” batteries.
