flash, you will hear beep sound per second until the problem has been corrected.
- Wrong communication. It refers to poor connection between charger and battery
pack .
- Internal temperature of the battery pack is out of range from 32°F to 122°F.
- Full voltage of the battery pack less than 32V.
- Short circuit of the output, or overload.
The power indicator LED lights
This Li-Ion battery pack is equipped with a power indicator which is used to give
an indication of the battery pack’s remaining charge. Press the power indicator
button to check battery charge as below. The LEDs will stay lit for approximately 4
seconds.
Meaning of power indicator:
Low capacity warning
Unlike other battery pack types, Lithium-Ion battery packs deliver fade-free power
for their entire run time. The tool will not experience a slow, gradual loss of power as
you work. If red LED on the battery pack begins to flash, the battery pack’s charge is
under 1% capacity and should be recharged.
