LEAVING THE BATTERY PACK IN THE CHARGER
The charger and battery pack can be left connected with the charge
indicator showing Pack Charged.
WEAK BATTERY PACKS: Weak batteries will continue to function but
should not be expected to perform as much work.
FAULTY BATTERY PACKS: This charger will not charge a faulty battery
pack. The charger will indicate faulty battery pack by refusing to light or
by displaying problem pack or charger.
PROBLEM POWER LINE
Some chargers have a Problem Powerline indicator. When the charger is
used with some portable power sources such as generators or sources
that convert DC to AC, the charger may temporarily suspend operation,
flashing the red light with two fast blinks followed by a pause. This
indicates the power source is out of limits.
NOTE: This could also mean a problem with a charger.

Important Charging Notes

1. To prevent excessive discharge of the vehicle battery, do not
charge more than one battery pack without operating the vehicle.
2. Disconnect charger from cigarette lighter socket when not in
use to prevent vehicle battery from discharging.
3. Longest life and best performance can be obtained if the
battery pack is charged when the air temperature is between
65 °F and 75 °F (18–24 °C). DO NOT charge the battery pack
in an air temperature below +40 °F (+4.5 °C), or above +105 °F
(+40.5 °C). This is important and will prevent serious damage to
the battery pack.
4. The charger and battery pack may become warm to touch while
charging. This is a normal condition, and does not indicate a
problem. To facilitate the cooling of the battery pack after use,
avoid placing the charger or battery pack in a warm environment
such as in a metal shed, or an uninsulated trailer.
5. If the battery pack does not charge properly:
a. Ensure the cigarette lighter operates when pushed in the socket.
b. Ensure the cigarette lighter operates when the vehicle's ignition
switch is in the accessory position.
6. The battery pack should be recharged when it fails to produce
sufficient power on jobs which were easily done previously. DO
NOT CONTINUE to use under these conditions. Follow the charging
procedure. You may also charge a partially used pack whenever
you desire with no adverse affect on the battery pack.
7. Foreign materials of a conductive nature such as, but not limited
to, grinding dust, metal chips, steel wool, aluminum foil, or any
buildup of metallic particles should be kept away from charger
cavities. Always unplug the charger from the power supply when
there is no battery pack in the cavity. Unplug charger before
attempting to clean.
8. Do not freeze or immerse charger in water or any other liquid.
WARNING:
Shock hazard. Don't allow any liquid to get
inside charger. Electric shock may result.
CAUTION:
Burn hazard. Do not submerge the battery pack in
any liquid or allow any liquid to enter the battery pack. Never attempt
to open the battery pack for any reason. If the plastic housing of the
battery pack breaks or cracks, return to a service center for recycling.

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.
SAVE THESE INSTRUCTIONS FOR FUTURE USE
