Shipping the 
 FLEXVOLT™ Battery
The D
WALT FLEXVOLT™ battery has two modes: Use and 
Shipping. 
Use Mode: When the FLEXVOLT™ battery stands alone or is 
in a D
WALT 20V Max* product, it will operate as a 20V 
Max* battery. When the FLEXVOLT™ battery is in a 60V Max* 
a non-compatible charger as battery pack may 
rupture causing serious personal injury. Consult 
the chart at the end of this manual for compatibility of 
batteries andchargers.
•  Charge the battery packs only in 
chargers.
•  DO NOT splash or immerse in water or otherliquids.
•  Do not store or use the tool and battery pack in 
locations where the temperature may reach or 
exceed 104°F (40°C) (such as outside sheds or metal 
buildings in summer). For best life store battery packs in 
a cool, drylocation. 
NOTE: Do not store the battery packs in a tool with 
the trigger switch locked on. Never tape the trigger 
switch in the ONposition.
•  Do not expose battery pack or tool/appliance to 
fire or excessive temperature. Exposure to fire or 
temperature above 265 °F (130 °C) may cause explosion.
•  Do not incinerate the battery pack even if it is 
severely damaged or is completely worn out. The 
battery pack can explode in a fire. Toxic fumes and 
materials are created when lithium-ion battery packs 
areburned.
•  If battery contents come into contact with the skin, 
immediately wash area with mild soap and water. If 
battery liquid gets into the eye, rinse water over the open 
eye for 15 minutes or until irritation ceases. If medical 
attention is needed, the battery electrolyte is composed of 
a mixture of liquid organic carbonates and lithiumsalts.
•  Contents of opened battery cells may cause 
respiratory irritation. Provide fresh air. If symptoms 
persist, seek medicalattention.
 
WARNING: Burn hazard. Battery liquid may be 
flammable if exposed to spark orflame.
 
WARNING: Fire hazard. Never attempt to open the 
battery pack for any reason. If the battery pack case 
is cracked or damaged, do not insert into the charger. 
Do not crush, drop or damage the 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 (e.g., pierced with a nail, hit with a hammer, 
stepped on). Damaged battery packs should be 
returned to the service center forrecycling.
Storage Recommendations
1.  The best storage place is one that is cool and dry, away 
from direct sunlight and excess heat or cold.
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.
Battery Pack Cleaning Instructions
Dirt and grease may be removed from the exterior of the 
battery using a cloth or soft non-metallic brush. Do not use 
water or any cleaningsolutions.
Fuel Gauge Battery Packs
Some 
 battery packs include a fuel gauge which 
consists of three green LED lights that indicate the level of 
charge remaining in the batterypack.
The fuel gauge is an indication of approximate levels of 
charge remaining in the battery pack according to the 
followingindicators:
75–100% charged
51–74% charged
< 50% charged
Pack needs to be charged
To actuate the fuel gauge, press and hold the fuel gauge 
button. A combination of the three green LED lights will 
illuminate designating the level of charge left. When the 
level of charge in the battery is below the usable limit, the 
fuel gauge will not illuminate and the battery will need to 
berecharged.
NOTE: The fuel gauge is only an indication of the charge left 
on the battery pack. It does not indicate tool functionality 
and is subject to variation based on product components, 
temperature and end-userapplication.

Transportation
 
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. Transporting batteries 
can possibly cause fires if the battery terminals 
inadvertently come in contact with conductive 
materials such as keys, coins, hand tools and the 
like. The US Department of Transportation Hazardous 
Material Regulations (HMR) actually prohibit 
transporting batteries in commerce or on airplanes 
in carry-on baggage UNLESS they are properly 
protected from short circuits. So when transporting 
individual battery packs, make sure that the battery 
terminals are protected and well insulated from 
materials that could contact them and cause a short 
circuit. NOTE:Li-ion batteries should not be put in 
checkedbaggage.
