Batteries and Chargers

This DeWALT rotary laser will accept all DeWALT 20volt lithium

ion batteries, but is built to best resist damage during a fall

when used with the following batteries: All 1.5Ah and 2Ah

DeWALT 20volt lithium ion batteries. The battery pack is not

fully charged out of the carton. Before using the battery pack

and charger, read the safety instructions below and then follow

charging proceduresoutlined. When ordering replacement

battery packs, be sure to include the catalog number

andvoltage.

Important Safety Instructions for All

BatteryPacks



WARNING: Read all safety warnings, instructions,

and cautionary markings for the battery pack,

charger and product. Failure to follow the warnings

and instructions may result in electric shock, fire

and/or seriousinjury.

• Do not charge or use the battery pack in explosive

atmospheres, such as in the presence of flammable

liquids, gases or dust. Inserting or removing the battery

pack from the charger may ignite the dust orfumes.

• NEVER force the battery pack into the charger. DO

NOT modify the battery pack in any way to fit into 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 andchargers.

• Charge the battery packs only in DeWALTchargers.

• DO NOT splash or immerse in water or otherliquids.

• DO NOT allow water or any liquid to enter batterypack.

• 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,

drylocation.

NOTE: Do not store the battery packs in a tool with the

trigger switch locked on. Never tape the trigger switch

in the ONposition.

• 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 areburned.

• Do not expose a battery pack or appliance to ﬁre or

excessive temperature. Exposure to ﬁre or temperature

above 265°F (130°C) may causeexplosion.

• 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 lithiumsalts.

• Contents of opened battery cells may cause respiratory

irritation. Provide fresh air. If symptoms persist, seek

medicalattention.

• Battery liquid may be flammable if exposed to spark

orflame.

• 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 forrecycling.
