Q.
When lithium ion batteries are already installed in equipment, PI 967 applies. In Section II of PI 967, there is a provision saying; “Each package containing more than four cells or more than two bartteries installed in equipment must be labeled with a lithium handling label (Figure 7.4.H), except for button cell batteries installed in equipment (including circuit boards).” If I have one device with one cell in one package, then it is easy to understand no lithium handling label is required. However, if I have 10 of those devices in one package, do I then need the lithium battery handling label? What about if the batteries were button cell batteries? (This Q&A was posted on June 30, however, there were some vague passages in the Question as well as an error in the Answer. It is therefore re-edited and re-posted.) (31 Aug 13)
