green. If the display LED and head show red, this means the battery is disconnected or over-
temperature. Allow to cool down and retry. If the problem persists contact CORE Lighting.
Normal charging achieves >95% of battery level in around 4.5 hours from empty when “BATT FULL”
is displayed in that menu option and the head shows green. The unit continues trickle charging after
this point indefinitely. Trickle-charge mode is useful for maintaining charge whilst units are in hire
stock. “BATT FULL” is seen when charge current drops below 0.1A (see DIAGnostics menu ‘AN1’).
Note – when charging the head LEDs are disabled and are converted to a charging operation
display.
DISCHARGING & LED Modes
There are three modes of operation: HIGH O/P, NORMAL, & LONG LIFE selectable on the main
menu.
HIGH O/P is 140% (so can be regarded as “Turbo” mode), NORMAL mode is 100% LED output and
LONG LIFE is 60% output (therefore 1.7 x lifespan).
Discharge lasts in excess of 6 hours in NORMAL LED colour-cycling mode “SLOW RNBW” with the
dimmer control at full (BRI% 100). LONG LIFE mode will achieve 8-10 hours. In practice the unit will
achieve longer life at normal operating temperatures providing the charging regime is maintained as
described above. Life may be further extended by reducing the dimmer to, say, 70% which will add
30% to life.
When the battery drops to a particular voltage the low battery red LED is activated permanently on
the lower right of the membrane keypad as a warning the battery needs recharging. When the
voltage drops further the unit simply switches off. This is to prevent over-discharge as a LiPo battery
can go into a non-recoverable mode in such a case. Smart monitoring of both the charge and
discharge cycles therefore helps to preserve the lifetime of the battery.
LIFESPAN
Once discharged it is important for the battery to be recharged as soon as possible to prevent long
term damage to the battery
. The battery should be capable of more than 500 recharge cycles if fully
discharged then fully recharged straight away to more than 90% battery capacity. Lighter use will
preserve battery life further (over 1000 cycles at 50% repeated discharge).

Battery Temperature
This may be monitored in the “BATT” menu option and is monitored by software so that excessive
heat shuts down the unit over-charging. A steady flashing red charge status LED indicates this has
occurred, meaning the battery temperature is over 45 deg.
The battery is capable of operation -20 to +50 deg.
