Special Provision A181 states: “When a package contains a combination of lithium batteries contained in equipment and lithium batteries packed in equipment, the package must be marked UN 3091 Lithium metal batteries packed with equipment or UN 3481 Lithium ion batteries packed with equipment as appropriate. If a package contains both lithium ion batteries and lithium metal batteries, the package must be marked as required for both battery types. However, button cell batteries installed in equipment (including circuit boards) need not be considered.” The meaning of this SP is as follows:

1) All applicable parts of both packing instructions must be met. The total mass of lithium batteries contained in any package must not exceed the limits for passenger aircraft or cargo aircraft, as applicable. Where a package contains both lithium metal and lithium ion batteries, the provisions of DGR 5.0.2.11 (g) “Q calculation” must be met.

2) The packages must be marked UN3091 Lithium metal batteries packed with equipment, or UN3481 Lithium ion batteries packed with equipment, as appropriate. If a package contains both lithium metal batteries and lithium ion batteries packed with and contained in equipment, the package must be marked as required for both battery types. However, button cell batteries installed in equipment (including circuit boards) need not be considered.

3) The dangerous goods declaration must indicate UN3091 Lithium metal batteries packed with equipment or UN3481 Lithium ion batteries packed with equipment as appropriate. If a package contains both lithium metal batteries and lithium ion batteries packed with and contained in equipment then the declaration must indicate both UN3091 Lithium metal batteries packed with equipment and UN3481 Lithium ion batteries packed with equipment and the requirements of DGR 5.0.2.11 Notes. 2 and DGR 8.1.6.9.2 Step 6. (g) “Q value” indication.
