BATTERY PROTECTION
The battery circuitry protects the battery pack from extreme temperature, over-
discharge, and over-charge. To protect the battery from damage and prolong its life,
the battery pack circuitry will turn off the battery pack if it becomes overloaded or if
the temperature becomes too high during use. This may happen in extremely high
torque, binding, and stalling situations. The battery pack will shut down with power
indicator flashing orange for 10s when its operating temperature exceeds 158°F
(70°C), and will begin normal operation when it returns to 152°F (67°C).
NOTICE:
A significantly reduced run time after fully charging the battery pack
indicates that the batteries are near the end of their usable life and must be replaced.
COLD WEATHER OPERATION
This Lithium-Ion battery pack will provide optimal performance in temperatures
between 41°F (5°C) and 104°F (40°C). When the battery pack is very cold, it may
"pulse" for the first minute of use to warm itself. Put the battery pack on a tool and use
the tool in a light application. After about a minute, the battery pack will have warmed
itself and will operate normally.
WHEN TO CHARGE THE BATTERY PACK
NOTICE:
Lithium-Ion battery packs are shipped partially charged. Before using it the
first time, fully charge the battery pack.
NOTICE:
This battery pack is equipped with an advanced self-maintenance function
to extend the battery life. Depending on the battery charge, it will automatically perform
a self-discharge operation after one month of storage. After this self-maintenance, the
battery pack will enter sleep mode and maintain 30% of its charge capacity. If stored
for a month or longer, fully recharge the battery before the next use.
It is not necessary to run down the battery pack charge before recharging. The Lithium-
Ion battery can be charged at any time and will not develop a "memory" when charged
after only a partial discharge. Use the power indicator to determine when the battery
pack needs to be recharged.
