 or batteries must comply with the following restrictions:

 1) for a lithium metal cell, the lithium content is not more than
 1 g;

 2) for a lithium metal or lithium alloy battery, the aggregate
 lithium content is not more than 2 g;

 3) for lithium ion cells, the Watt-hour rating (see Attachment 2)
