Battery Recovery Indicators

There are certain conditions that produce an unrecoverable
battery indication (the red light on the front of the battery
flashes). The most common causes for unrecoverable
battery conditions are:
If the LED on the front of the battery flashes red, take the
battery out, wait 20 seconds and then press the battery
status button. If the light continues to flash red, the
battery can no longer be used. Replace with a new battery.
Optimizing Battery Operation
If you wish to check the charge of any Lithium-ION
battery after the LEDs have turned off, press the
battery status button to the right of the LEDs on the
battery pack and they will light once again.
Low battery state. As the battery discharges, LEDs
will turn off one at a time from right to left until the
battery is almost depleted. At that time, the last green
LED will turn off and a red LED comes on. At the
point of near depletion the red LED will begin to flash.
As you recharge batteries, the red LED no longer
flashes, and will eventually turn green as the charge
increases.
