1.Single cell designation rule is composed of 6 parts:

First part: Oceansun abbreviation
Second part: Electro-Chemistry System
(For example : M-- Ni-MH,D-- Ni-Cd,L-- Li ion)
Third part: Model
(For example: A .AA.AAA.SC.C.D etc.)
Forth part: Sub model
("H" means high cap ,No "H" means flat cap,For prismatic cell, 6&8 are the sub models we will distinguish them by adding bar between them and nominal capacity)
Fifth part: Nominal capacity
Sixth part: Discharge rate
( S: standard type P: high rate type)

For example:
OSM-AA2000S means Oceansun Ni-MH flat cap AA2000 standard type battery
O S M -- AA (H) 2000 S

2.Battery pack designation rule is composed of 8 parts:

First part: The number of cells
Second part: Oceansun abbreviation
Third part: Electro-Chemistry System
(For example : M-- NiH,D-- Ni-Cd,L-- Li ion)
Forth part: Model
(For example: A .AA.AAA.SC.C.D etc.)
Fifth part: Sub model
("H" means high cap ,No "H" means flat cap,For prismatic cell, 6&8 are the sub models we will distinguish them by adding bar between them and nominal capacity)
Sixth part: Nominal capacity
Seventh part: Discharge rate
( S: standard type P: high rate type)
Eighth part: Configuration code
( Code V , code H , code S , code Y, code Z , code T)

For example
3OSM-AAH2000SH means
3 -- 3 cells in the park
OS -- oceansun battery
M -- Ni-MH
AA -- model AA
H -- high cap
2000 -- nominal capacity
S -- standard type
H -- code H
