Model of square lithium ion

- Aug 09, 2019-

For a square lithium ion battery, the model number is generally 6 digits. As shown in the table below. The first two digits are the thickness of the battery with one decimal place; the middle two digits are the width of the battery; the last two digits are the length of the battery. The unit is millimeters. For example, the 606168 lithium battery has a thickness of 6.0 mm, a width of 61 mm, and a length of 68 mm. (Note: Due to the different packaging methods used by battery manufacturers, the capacity of the same type of square lithium-ion battery is less than 300mAh)

The nominal voltage of a square lithium ion battery is generally 3.6 to 3.7V, and the charge termination voltage is generally 4.2V.
