When the LED is not set to
constantly lit
About 300 hours (continuous use)
About 20 days (regular use: 5 hrs/
day)
LED not set to constantly lit and the
air-float used for half an hour per day
About 80 hours (continuous use)
About 3.3 days (regular use: 5 hrs/
day)
LED constantly lit
About 100 hours (continuous use)
About 13.5 days (regular use: 5 hrs/
day)
If the LED is constantly lit and the
air-float function is used, the battery
life will be reduced to about 2/3 of
the above value.
If the air-float function is not used on air-float equipped models, the battery
life will be approximately the same as models without the air-float function.
If the constant LED or air-float functions will be frequently used, the
optional AC adapter is recommended.
