Models and Sizes of Common Mn Zn Batteries and Li MnO₂ Button Batteries

Battery model editing
Generally divided into: 1.2.3.5.7, of which No. 5 and No. 7 are particularly commonly used. The so-called AA battery is No. 5 battery, and AAA battery is No. 7 battery.

D-type battery (large battery / lr20 / AM1) has a diameter of 34.2 and a height of 61.5mm

Type C battery (No.2 battery / LR14 / AM2) has a diameter of ф 26.2 and a height of 50.0 mm

AA type battery (No.5 battery / LR6 / AM3) has a diameter of ф 14.5 and a height of 50.5mm

The diameter of AAA type battery (No.7 battery / LR03 / AM4) is ф 10.5 and the height is 44.5mm

AA / 2 battery (No.8 battery LR1 / Am5) has a diameter of Φ 11.0 and a height of 30.0 mm

AAAA battery (No.9 battery / lr61 / am6) with diameter of ф 8.0 and height of 39.5mm

AAAA / 2 battery (small No.9 battery / lr61 / am6) with diameter of ф 8.0 and height of 28.0 mm

Talk about the common "AAAA, AAA, AA, a, SC, C, D, N, F" models

AAAA model is rare, disposable AAAA strong alkaline battery can be seen occasionally, usually used in a computer pen. The standard AAAA (flat head) battery is 41.5 ± 0.5mm in height and 8.1 ± 0.2mm in diameter.

AAA type battery is more common, the former MP3 used AAA battery, the standard AAA (flat head) battery height is 43.6 ± 0.5mm, diameter is 10.1 ± 0.2mm.

AA batteries are well known to all. Digital cameras and electric toys can not do without AA batteries. The standard AA (flat head) batteries are 48.0 ± 0.5mm in height and 14.1 ± 0.2mm in diameter.

It is not common to use only one a to indicate the type of battery. This series is usually used as the battery cell in the battery pack. The Ni Cd and Ni MH batteries for old cameras are almost 4 / 5A or 4 / 5sc. The standard a (flat head) battery is 49.0 ± 0.5mm in height and 16.8 ± 0.2mm in diameter.

SC model is not common. It is generally the battery cell in the battery pack, which can be seen on electric tools, cameras and imported equipment. The standard SC (flat head) battery is 42.0 ± 0.5mm in height and 22.1 ± 0.2mm in diameter.

The standard C (flat head) battery is 49.5 ± 0.5mm in height and 25.3 ± 0.2mm in diameter.

Model D is No.1 battery, which is widely used in civil, military and special DC power supply. The standard D (flat head) battery is 59.0 ± 0.5mm in height and 32.3 ± 0.2mm in diameter.

The standard n (flat head) battery is 28.5 ± 0.5mm in height and 11.7 ± 0.2mm in diameter.

F-type battery, electric scooter and power battery are new generation products, which have the trend of replacing lead-acid maintenance free batteries. They are generally used as battery cells (personal opinion: actually, they are too large to be used alone, ha ha). The standard f (flat head) battery is 89.0 ± 0.5mm in height and 32.3 ± 0.2mm in diameter.

We have noticed that the word "flat head" refers to that the positive pole of the battery is flat without protrusion. Generally, the height of the battery cell used for spot welding of the battery pack is 0.5mm higher than that of the battery with the same type of pointed head (which can be used for single battery power supply). and so on. In addition, batteries are often not regular "AAA, AA, a, SC, C, D, N, F". In front of them, there are scores of "1 / 3, 2 / 3, 1 / 2, 2 / 3, 4 / 5, 5 / 4, 7 / 5". These scores indicate the corresponding height of the cell. For example, "2 / 3AA" means that the height is 2 / 3 of the charging battery of the general AA battery; for example, "4 / 5A" means that the height is the general a-battery 4 / 5 of the pool's rechargeable batteries.

There are also two kinds of model representation methods, which are five digits, for example, 145001749026500. The first two digits refer to the diameter of the cell body, and the last three digits refer to the height of the cell. For example, 14500 refers to AA battery, which is about 14mm in diameter and 50mm in height.

For example, 505060ar, 305060a, where the first two digits refer to the thickness, the middle two digits refer to the width, and the last two digits refer to the length. For example, 505060ar is 5.0 mm thick, 50 mm wide and 60 mm long. The suffix ar stands for aluminum shell lithium battery.
