Currently I am looking for eight new 18650 battery cells to rebuild my iBook G4 (A1055) battery pack. Because I can't find for what discharge rate the original cells are rated, I'm not sure which cells to pick. The original cells are Panasonic CGR18650CA (datasheet is for a slightly different type, I know), but in the datasheet is not specifically described what the maximum discharge rate can be. There is a mention of actual capacity vs discharge rate, the highest being 4080mA given as an example. Is there a general 'safe' rating for laptop battery pack cells?
The cell type I am planning to buy is the Samsung ICR18650-26H. This cell can have a discharge rate of 5200mA.
Here is a schematic of the cells as connected in the iBook G4 battery:
