Charge Cycle Counter
Press the fuel gauge button for twenty (20) seconds to
read the charge cycle counter.
Count number of flashes to figure out cycle count.
Example 1:
L1 - Flashes one (1) time
L2 - Flashes three (3) times
L3 - Flashes four (4) times
L4 - Flashes fi ve (5) times
It means battery was charged 1, 345 times
Example 2:
L1 - No fl ashes
L2 - Flashes six (6) times
L3 - Flashes seven (7) times
L4 - Flashes eight (8) times
It means battery was charged 678 times
Battery Pack Protection
To maximize performance and battery life, the Lithium-
Ion battery's protection circuit monitors battery voltage,
discharge amperage and temperature.
When the battery voltage falls below the usable range,
the battery will shut off, and the 1st LED will flash. After
the trigger is released, the LED will stop flashing when
the battery voltage returns to the usable range. If the 1st
LED continues to flash for more than a few seconds, the
battery needs charging.
Battery over temperature - indicated by all (4) LED lights
flashing on the battery.
temperature of the battery is too high and it will stop the
battery operation to prolong battery life. The lights will
continue to flash for four (4) minutes after each trigger
pull until temperature lowers to an acceptable level.
External fan cooling can be used to speed the battery
cooling time.
If a hot or cold battery is placed on charger, charger will
not charge the battery and will be indicated by a Yellow
flashing light on the charger. The charger goes into a fast
charge mode when the battery temperature is between
32 F (0°C) and 113 F (45°C).
Cold Weather Operation
The Lithium-Ion battery can be used in temperatures
down to -4°F(-20°C). When the battery pack is very cold,
run the tool at no load to warm battery and then use the
tool normally.
Hot Weather Operation
If the Lithium-Ion battery temperature reaches
158°F(70°C), the protection circuit will turn off the
battery and all four LED's will flash. Once the battery has
cooled down below 149°F(65°C), the battery will resume
normal operation.
