Photogenic Professional Lighting AKB-1 Battery - Manual (Page 5)

Your new fully charged power pack will provide between 100 to 200 full
charge flashes depending on the model you have. This is an
approximation for full power flashes and dialing down power can
increase the number of charges you will have for your light. Carry a
backup battery when you are in the field for extended periods of time, or
do not have access to power.
Note: When you are using the light in battery mode, the
modeling circuit is disabled to prevent incidental draining of
battery power. Using the lights in AC mode, the modeling circuits are
fully functional.
Connecting to your Light.
1. Make sure both the battery and the light are switched to the
OFF position.
2. Connect the battery-to-light cable to the light and then to
the battery.
3. Move the flash/charge switch on the battery to FLASH.
4. Move the power switch on the light from OFF to Flash.
(If
your flash unit has a modeling light, be sure it is off, or the
battery will not charge the flash.)
5. After the light switch is moved to flash, turn the battery
power switch to ON. Your battery is now charging the light
unit. The ready light on the back of the light will indicate
when it has been charged to the selected power level. The
ready light on the battery will begin to blink as an indication
that the light has been charged. This LED will continue to
blink until the light is discharged. It is recommended that
you turn the battery to off to conserve energy if the light is
not in use.
Maintaining your battery.

It is a good practice to periodically recharge your battery to
maintain the pack in the best condition. We recommend every
two weeks even if you do not plan to use the pack within this
interval.

Give your battery pack a rest after 15 to 30 minutes of use. The
pack will generate heat during the recharge cycles and this rest
will allow the pack to cool and lengthen its useful life.
