be excepted from being classified as a fully regulated Class 
9 Hazardous material. In general, the two instances that 
require shipping Class 9 are:
1.  Air shipping more than two STANLEY lithium-ion 
battery packs when the package contains only battery 
packs (no tools), and 
2.  Any shipment containing a lithium-ion battery with an 
energy rating greater than 100 watt hours (Wh). All 
lithium-ion batteries have the watt hour rating marked 
on the pack. Regardless of whether a shipment is 
considered excepted or fully regulated, it is the shipper’s 
responsibility to consult
Regardless of whether a shipment is considered excepted

materials. When transporting batteries, make sure that 
the battery terminals are protected and well insulated from

depleted of charge. The battery pack will need to be 
recharged before use.
