Battery Date Code

Browsing to the E2 service manual, that was recently posted in a thread in E2 board, I found some interesting info for our phone batteries:

Battery Date Code
The battery date code is a 15 position alphanumeric code that provides, back end
manufacture site information, year and week of manufacture date, cell type and
vendor information.
The battery date code is used for cell phone batteries that were manufactured
beginning in March 2000. The following paragraphs provide more detail about the
battery date code.

1. Backend Pack Manufacturing Site (first position of battery code)
A = Motorola Penang
B = T.D.I. Mexico
C = Motorola China
U = T.D.I. Hungary
D = T.D.I. Shanghai, China
E = ESG, Evadin, Brazil
F = ESG, Propower, Korea
H = Motorola Harvard
I = Motorola lreland
J= ESG, Chihuahua
K= T.D.I. Romeoville
L = Motorola Lawrenceville
M = TDI, Malaysia V =
N = TDI, Manau, Brazil
X = ESG, Foxlink, China

used, place a period in the sixth position.

4. Line and shift manufactured (optional) (seventh and eighth positions of battery
code)

Example of a battery date code: A1V90311JCCC...
position 1 = A = Motorola Penang.t (Backend Pack)
position 2 & 3 = 1V = Panasonic, AAA, HHR55B2
position 4, 5 & 6 = 903 = cell date code (from manufacturer)
position 7 & 8 = 11 = (TBD by supplier.Example: Line one of the first shift.)

8. Batteries sold in China have a 16 character date code:
Example: YYYYMMDDABCXXXX
Where YYYYMMDD is the actual battery manufacturing date
A is the line number
