2-5 Charge time and service time of power pack
1 The reference charge time spent in fully charging an exhausted battery at a room temperature of 25˚C is indicated
below:
Charge time
With main unit charger About 90 minutes
With power pack charger About 120 minutes
Keep in mind that charge time will vary depending on what condition the power source is placed under, how high its
ambient temperature is, and how often it is used for charging.
Generally, charge time will increase with the frequency of use because of power pack's degradation.
2 Service time of power pack
Service time About 40 minutes at a time
Keep in mind that power pack's service time will vary depending on how high its ambient temperature is, and how
often it was charged.
Generally, the power pack 's service time will decrease with its frequency of use because of its deterioration.
3 Power pack's service lifetime (as a standard to determine when the power pack in service should be replaced by a
new one).
The power pack's service time after about 500 cycles of charging and discharging at an ambient temperature of 20
Åé is approximately 20 minutes (as a standard to determine how long the service time will be).
If the service time seems to be shorter, replace it by a new one.
If, the power pack should be left unused after charging fully, its performance will gradually decrease even if it will not
be used at all.
If you have spare power packs, periodically, utilize all your power packs by turns to keep their performance as high
as possible.
Do not keep the lamp operating for a long time to avoid a burn your may suffer from a hot
lamp-house.
