BATTERY AND CHARGER SAFETY FEATURES
OVER CHARGING PROTECTION
The over charging protection will ensure that the battery is never overcharged. When the
battery has reached its fully charge capacity, the charger will automatic shut off, protecting
the internal components of the battery from being damaged.
OVER DISCHARGE PROTECTION
An internal component of the battery pack is an over discharge protector. This feature will
stop the battery from discharging beyond the recommended lowest safety voltage.
OVER HEAT PROTECTION
The battery has an internai thermister cut off censor which will cease the charging cycle if
the battery becomes hot during the charging process. This thermister censor will also stop
the battery from operating should the battery become too hot during the operation of the
tool. This can happen when the tool is overloaded or being used for extended periods of
time.
Up to 30 minutes in cooling time may be required depending on ambient temperature and
operation being performed.
OVER CURRENT PROTECTION
Should the battery be overloaded and the maximum current draw be exceeded, the battery
will temporarily stop working to protect the internal components. The battery will resume to
normal operation once the excessive current draw has returned to normal safe level. This
may take a few seconds.
