30、ure. Note 2 to entry: The cell does not require addition to the electrolyte and is designed to operate during its life in its original sealed state. Note 3 to entry: The nickel-metal hydride cell, however, may release gas towards the end of its life due to the accumulation of hydrogen in the cell. S

NOTE These types of cells are typically but not exclusively used for the following discharge rates L up to 0,5 It A, M up to 3,5 It A, H up to 7,0

38、It A, X up to and above 7,0 It A. This group of two letters shall be followed by a group of figures indicative of the rated capacity of the cell in ampere-hours. Cells that have been tested at 20 C and 5 C but not at 18 C shall carry an additional marking of T5. For example: HPH 100 or HPH 100 T5. B

40、ings giving the following minimum information: type of cell (designation as specified in 5.1; in addition, it is permissible for a manufacturer to use his own type designation); name or identification of manufacturer or supplier; positive terminal: either a red washer or an indented or raised symbol

41、, (see graphical symbol 5005 of IEC 60417:2002). 5.4 Safety recommendations The manufacturer shall provide recommendations for the safe handling of the cell.
