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
(i.e., packed in suitcases and carry-on luggage) UNLESS they are properly protected
from short circuits. So when transporting individual batteries, 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 checked baggage.

Charging ProCedure
The standard charger provided will charge a fully
depeleted battery in about 4 hours.

charged and may be used at this time or left on the
charger.
Recharge discharged batteries as soon as possible after use or battery life may be
greatly diminished.

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.
2.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.
3. If the battery pack does not charge properly:
a. Check current at receptacle by plugging in a lamp or other appliance
b. Check to see if receptacle is connected to a light switch which turns power off
when you turn out the lights.
 c.Movechargerandbatterypacktoalocationwherethesurroundingair 
  temperatureisapproximately65°F-75°F(18°-24°C).
d. If charging problems persist, take the tool, battery pack and charger to your
local service center.
4. 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.
5.Foreignmaterialsofaconductivenaturesuchas,butnotlimitedto,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

6.Donotfreezeorimmersechargerinwateroranyotherliquid.
WARNING: Shock hazard. Do not allow any liquid to get inside charger. 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.
