Code

Description

1. position

Describes the negative Electrode:
I: Li-Ion
L: Lithium metal or Li-alloy

2. position

Describes the positive Electrode
C: based in cobalt
N: based on Nickel
M: based on Mangan
V: based on Vanadium

3. position

Battery shape:
R: Round
P: Prismatic

Cell size for round cells

4.+5. position

Diameter  in mm

6.-8. position

High in 1/10 mm

Example
ICR 18650

Round Li-Ion cell  pos. cobalt based Elektrode. Diameter ca. 18 mm, High: 65 mm

Cell size for prismatic cells

4. + 5. position

Thickness in 1/10 mm

6. + 7. position

Wideness in mm

8. + 9. position

High in mm

Example
ICP 772530

Prismatic Li-Ion cell with pos. cobalt based electrode. Wide: 25 mm, Thick: 7.7mm, High 30 mm

Additionl

If the size is more than 100 mm (10 mm) then the number groups are separated by a slash. The groups can then be enlarged as necessary.

In case of thin prismatic cells, the groups can be separated by a T. Then the size is given in 1/10 mm units.
