WARNING: Burn hazard. Battery liquid may be flammable if exposed to spark or flame.

WARNING: Never attempt to open the battery pack for any reason. If battery pack case
is cracked or damaged, do not insert into charger. Do not crush, drop or damage battery
pack. Do not use a battery pack or charger that has received a sharp blow, been dropped,
run over or damaged in any way (i.e., pierced with a nail, hit with a hammer, stepped on).
Electric shock or electrocution may result. Damaged battery packs should be returned to
service centre for recycling.

WARNING: Fire hazard. Do not store or carry the battery pack so that metal
objects can contact exposed battery terminals. For example, do not place the battery
pack in aprons, pockets, tool boxes, product kit boxes, drawers, etc., with loose nails,
screws, keys, etc.

CAUTION: When not in use, place tool on its side on a stable surface where it will
not cause a tripping or falling hazard. Some tools with large battery packs will stand
upright on the battery pack but may be easily knocked over.
Transportation

WARNING: Fire hazard. Transporting batteries can possibly cause fire if the battery
terminals inadvertently come in contact with conductive materials. When transporting
batteries, make sure that the battery terminals are protected and well insulated from
materials that could contact them and cause a short circuit.
NOTE: Lithium-ion batteries should not be put in checked baggage.
D WALT batteries comply with all applicable shipping regulations as prescribed by industry
e
and legal standards which include UN Recommendations on the Transport of Dangerous
Goods; International Air Transport Association (IATA) Dangerous Goods Regulations,
International Maritime Dangerous Goods (IMDG) Regulations, and the European Agreement
Concerning The International Carriage of Dangerous Goods by Road (ADR). Lithium-ion cells
and batteries have been tested to section 38.3 of the UN Recommendations on the Transport
of Dangerous Goods Manual of Tests and Criteria.
In most instances, shipping a D WALT battery pack will be excepted from being classified as a
e
fully regulated Class 9 Hazardous Material. In general, only shipments containing a lithium-ion
battery with an energy rating greater than 100 Watt Hours (Wh) will require being shipped
as fully regulated Class 9. All lithium-ion batteries have the Watt Hour rating marked on the
pack. Furthermore, due to regulation complexities, D
lithium-ion battery packs alone regardless of Watt Hour rating. Shipments of tools with
batteries (combo kits) can be air shipped as excepted if the Watt Hour rating of the battery
pack is no greater than 100 Whr.
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
documentation requirements.
The information provided in this section of the manual is provided in good faith and believed
to be accurate at the time the document was created. However, no warranty, expressed or
implied, is given. It is the buyer's responsibility to ensure that its activities comply with the
applicable regulations.
Transporting the FlEXVOlT Battery
TM
battery has two modes: Use and Transport.
The D WALT FLEXVOLT TM
e
Use Mode: When the FLEXVOLT battery stands alone or is in a D
TM
will operate as an 18V battery. When the FLEXVOLT
batteries) product, it will operate as a 54V battery.
Transport Mode: When the cap is attached to the FLEXVOLT
Transport mode. Keep the cap for shipping.
When in Transport mode, strings of cells are electrically
disconnected within the pack resulting in 3 batteries with a
lower Watt hour (Wh) rating as compared to 1 battery with a
higher Watt hour rating. This increased quantity of 3 batteries
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
3 x 36 Wh, meaning 3 batteries of 36 Wh each. The Use
Wh rating might indicate 108 Wh (1 battery implied).

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 in use.
2. For long storage, it is recommended to store a fully charged battery pack in a cool, dry
place out of the charger for optimal results.
nOTE: Battery packs should not be stored completely depleted of charge. The battery pack
will need to be recharged before use.
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:
