In most instances, shipping a 
DeWALT
 battery pack will 
be excepted from being classified as a fully regulated 
Class9Hazardous Material. In general, only shipments containing 
a lithium-ion battery with an energy rating greater than 100Watt 
Hours (Wh) will require being shipped as fully regula 
WALT
 does 
not recommend air shipping lithium-ion battery packs alone 
regardless of Wh rating. Shipments of tools with batteries (combo 
kits) can be air shipped as excepted if the Wh rating of the battery 
pack is no greater than 100Wh.
Regardless of whether a shipment is considered excepted 
or fully regulated, it is the shipper's responsibility to consult 
the latest regulations for packaging, labeling/marking and 
documentationrequirements.
The information provided in this section of the manual is

Transporting the FLEXVOLT
TM
 Battery
The DeWALT FLEXVOLT
TM
 battery has two modes: Use 
andTransport.
Use Mode: When the FLEXVOLT
TM
 battery stands alone or is in 
a DeWALT 18V product, it will operate as an 18V battery. When 
the FLEXVOLT
TM
 battery is in a 54V or a 108V (two 54V batteries) 
product, it will operate as a 54Vbattery.
Transport Mode: When the cap is attached to the FLEXVOLT
TM
 
battery, the battery is in Transport mode. Keep the cap 
forshipping.
When in Transport mode, strings 
of cells are electrically 
disconnected within the pack, 
resulting in 3batteries with a 
lower Watt hour (Wh) rating as compared to 1battery with a 
higher Watt hour rating. This increased quantity of 3batteries 
with the lower Watt hour rating can exempt the pack from 
certain shipping regulations that are imposed upon the higher 
Watt hour batteries. 
For example, the Transport Wh rating might indicate 
3x36Wh, meaning 
3batteries of 36Wh 
each. The Use Wh rating 
might indicate 108Wh 
(1batteryimplied).
Storage Recommendations
1.  The best storage place is one that is cool and dry away 
from direct sunlight and excess heat or cold. For optimum 
battery performance and life, store battery packs at room 
temperature when not inuse.
2.  For long storage, it is recommended to store a fully charged 
battery pack in a cool, dry place out of the charger for 
optimalresults.
NOTE: Battery packs should not be stored completely depleted 
of charge. The battery pack will need to be recharged beforeuse.
Example of Use and Transport Label Marking
Labels on Charger and Battery Pack
In addition to the pictographs used in this manual, the labels 
on the charger and the battery pack may show the following 
pictographs:
Read instruction manual beforeuse.
See Technical Data for chargingtime.
Do not probe with conductiveobjects.
Do not charge damaged batterypacks.
Do not expose to water. 
Have defective cords replacedimmediately.
Charge only between 4 ˚C and 40 ˚C.
Only for indooruse.
Discard the battery pack with due care for 
theenvironment.
Charge DeWALT battery packs only with designated 
DeWALT chargers. Charging battery packs other 
than the designated DeWALT batteries with a 
DeWALT charger may make them burst or lead to 
other dangeroussituations.
Do not incinerate the batterypack.
USE (without transport cap). Example: Wh rating 
indicates 108 Wh (1 battery with 108 Wh). 
TRANSPORT (with built-in transport cap). Example: 
Wh rating indicates 3 x 36 Wh (3batteries of 36 Wh).
