DeWalt DXAELJ16 Instruction Manual page 6

• Avoid storing this lithium battery powered unit in the basement,
bathroom or other areas of the house that are or may become
wet or humid or where moisture may concentrate.
• Do not leave this lithium battery powered unit in direct sunlight,
or use or store the unit inside cars in hot weather. Doing so may
cause the battery to generate heat, rupture, or ignite. Using the
battery in this manner may also result in a loss of performance and
a shortened life expectancy.
• Never charge this unit near heat or flammable objects.
• NEVER THROW WATER ON A BURNING LITHIUM BATTERY!
If a lithium battery does catch on fire, it will burn even more violently
if it comes in contact with water or even moisture in the air. A fire
extinguisher must be used.
Battery Charging and Capacity
This unit is delivered in a partially charged state – you must fully
charge it before using it for the first time.
When stored at room temperature with a full charge, lithium
batteries will begin to discharge from the time they are
manufactured, even when unused. Deep discharges also decrease
their capacity. Battery life can be extended by the following:
• Charge battery to full capacity before storage.
• Store this unit at temperatures between 5°C and 20°C (41°F and
68°F).
• Never discharge the battery fully.
• Charge after each use.
• Always charge at least once every 3-6 months if not in frequent
use to prevent overdischarge.
Transportation of Lithium Batteries
• Always check all applicable local, national, and international
regulations before transporting a unit containing a lithium battery.
• Transporting an end-of-life, damaged, or recalled battery may, in
certain cases, be specifically limited or prohibited.
INSTRUCTIONS PERTAINING TO THE
12V DC/USB CHARGING ADAPTER
CAUTION – To avoid the risk of property damage:
• The 12 Volt DC charging adapter must only be connected to
batteries with a nominal output voltage of 12 volts. The unit will
not operate from a 6 volt battery and will sustain permanent
damage if connected to a 24 volt battery.
• Always connect the 12 volt DC/USB charging adapter to the 12
volt DC power source before plugging any devices into it.
• NEVER connect the 12V DC/USB charging adapter to a
positive grounded vehicle.
Specific Safety Instructions for
Jump Starters
WARNING – Burst hazard: Do not use the unit for charging dry-cell
batteries that are commonly used with home appliances. These
batteries may burst and cause injury to persons and damage property.
Use the unit for boosting a lead-acid battery only. It is not intended to
supply power to a low-voltage electrical system other than in a starter-
motor application.
WARNING: To reduce the risk of electric shock, never immerse this
unit in water or any other liquid, or use when wet.
WARNING – Risk of explosive gases:
• Working in the vicinity of a lead acid battery is dangerous. Batteries
generate explosive gases during normal battery operation. For this
reason, it is of the utmost importance that each time before using
the jump-starter you read this manual and follow instructions exactly.
• To reduce the risk of battery explosion, follow these instructions and
those published by the battery manufacturer and manufacturer of
any equipment you intend to use in the vicinity of the battery. Review
cautionary markings on these products and on the engine.
WARNING – To reduce the risk of fire:
