Battery charging battery care
Dermaray Laser Combs contains a high quality Li-Ion rechargeable battery and is
supplied with a universal (100-240v @ 50-60Hz) battery charger. The power cable
with wall connector can be changed to suit different locations with different wall
power sockets.
The high quality Japanese Li-Ion battery used in the Dermaray Laser are reliable
and not susceptible to the “chemical memory” problems of older NiCad batteries,
and is the same type of battery used in mobile telephones. It is recommended to
perform a full charge prior to initial use of your Dermaray® - Laser to ensure the
best performance and extend the life of your batteries.
Connect the Dermaray Laser to mains power for a minimum of 12 hours prior to
initial use. The CHARGING indicator should glow yellow when charging. The
CHARGING indicator will go out (not be lit) when fully charged. However, for the
initial charge, leave connected for a total of 12 hours which will include time after
the charge indicator stops. Future charging is completed once the yellow
CHARGING indicator goes out (not be lit.)
After the initial long charge, Dermaray Laser can be charged between each use and
disconnected from charge once the battery charge indicator shows battery full, or it
can be charged when the unit indicates low battery.
Dermaray Laser can be connected to mains power when the battery low indicator
sounds. The low battery indicator will sound and display a low battery message with
approximately 1 hour of treatment time left and again every 60 seconds whilst in
use (with 5 minutes left). Batteries will charge while the device is in use, however it
is recommended that treatment be suspended while the batteries are charging.
Fully charged batteries will give approximately 3~7 hours of treatment time
depending on the laser configuration, this time may be reduced if the device has not
been charged for some time.
The battery charger that is built into the unit is intelligent and protects against over-
charging and resulting battery damage by constantly measuring battery voltage and
te
mperature. When connected to power and charging the LED indicator “charging”
will glow yellow, see below for detailed view.
