Charging The Battery - Stanley SCH20 Manual

Use
WARNING! Let the tool work at its own pace.
Do not overload.

Charging the battery

The battery needs to be charged before first use and whenev-
er it fails to produce sufficient power on jobs that were easily
done before. The battery may become warm while charging;
this is normal and does not indicate a problem.
WARNING! Do not charge the battery at ambient tempera-
tures below 10 °C or above 40 °C. Recommended charging
temperature: approx. 24 °C.
NOTE: The charger will not charge a battery if the cell tem-
perature is below approximately 10 °C or above 40 °C.
The battery should be left in the charger and the charger
will begin to charge automatically when the cell temperature
warms up or cools down.
• Plug the charger into an appropriate outlet before insert-
ing the battery pack.
• Insert the battery pack into the charger.
The green LED will flash indicating that the battery is being
charged.
The completion of charge is indicated by the green LED
remaining on continuously. The pack is fully charged and may
be used at this time or left in the charger.
Warning! Recharge discharged batteries as soon as possible
after use or battery life may be greatly diminished.
Charger diagnostics
This charger is designed to detect certain problems that can
arise with the battery packs or the power source. Problems
are indicated by one LED flashing in different patterns.
Bad Battery
The charger can detect a weak or damaged battery. The red
LED flashes in the pattern indicated on the label. If you see
this bad battery blink pattern, do not continue to charge the
battery. Return it to a service centre or a collection site for
recycling.
Hot/Cold Pack Delay
When the charger detects a battery that is excessively hot or
excessively cold, it automatically starts a Hot/Cold Pack delay,
suspending charging until the battery has normalised. After
this happens, the charger automatically switches to the Pack
Charging mode. This feature ensures maximum battery life.
The red LED flashes in the pattern indicated on the label when
the Hot/Cold pack delay is detected.
Problem Power Line
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. The LED flashes
in the pattern indicated on the label. This indicates that the
power source is out of limits.
Leaving the battery in the charger
The charger and battery pack can be left connected with the
LED glowing indefinitely. The charger will keep the battery
pack fresh and fully charged.
Important charging Notes
• 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.
• 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.
• If the battery pack does not charge properly:
• Check current at receptacle by plugging in a lamp or
other appliance.
• Check to see if receptacle is connected to a light
switch which turns power off when you turn out the lights.
