The term ‘accu’ refers to a storage battery or rechargeable battery. It makes use of a group of electrochemical cells or secondary cells to operate. It utilizes electrically reversible electrochemical reactions. The secondary cell chemistries commonly used for this particular type of battery include lithium ion polymer, nickel metal hydride and lead acid. Furthermore, it is also possible to use lithium ion as well as nickel cadmium. In order to understand it better, it is good to know the different accu dimensions.
The Dimensions of an Accu
The accu is classified into various types. One of these is the AAA battery, which is also called by other names like the MX2400, MN2400 and microlight. This cylindrical-shaped storage battery has a length of 44.5 millimeters, while its diameter is 10.5 millimeters. Another common type of rechargeable battery is the AA, which is also called the MN1500, mignon and penlight. The standard length is 50.5 millimeters, the diameter of which ranges from 13.5 millimeters to 14.5 millimeters. Also called by names like the baby, MX1400 and MN1400, the C battery has a length of 50 millimeters, with a diameter measuring 26.2 millimeters.
The D battery is also called the MX1300, MN1300 and flashlight battery, the length of which is 61.5 millimeters while the diameter is 34.2 millimeters. The 9-volt battery is rectangular, which is also known as the square battery, MN1604 and radio battery. It has a height of 48.5 millimeters, a length of 26.5 millimeters and a width of 17.5 millimeters. Next, there is the spring or lantern battery, which is also called the MN908, spring top and 6-volt. It is 115 millimeters high, 68.2 millimeters long and 68.2 millimeters wide.
Additional Facts and Other Interesting Details
In addition to the common batteries, some are used less often compared to others. These include the AAAA battery, which is also called the MX2500. Often used in electronic glucose meters and pen flashlights, such obscure battery has a length of 42.5 millimeters and a diameter measuring 8.3 millimeters.
Another type of seldom-used battery is the A23 battery, which is commonly found in smaller radiofrequency devices like keyless entry systems and garage door openers. It has a length of 29 millimeters and a diameter measuring 10 millimeters.
The 18650 battery is used widely on cameras and LED flashlights. It has a length of 65 millimeters, with a diameter measuring 18 millimeters. Commonly referred to as the camera battery, the CR123A is also called by other names such as the RCR123A and 123. It has a diameter measuring 17 millimeters, the average length of which is 34.5 millimeters.
The duplex is another interesting type of battery, mainly because it is comprised of a couple of 1.5-volt cells on the inside. It has a diameter measuring 21.8 millimeters, while its supposed length is 74.6 millimeters.
