information), adds an additional level of safety to help ensure that even if the charger does not end
the charging process correctly per the battery chemistry/type, it will still end the charging process
when the set capacity has been reached. Some users purposely use a lower Capacity Limit
Percentage in order to stop the charge mode below full capacity as a means to increase cycle life. To
adjust the CHG Capacity Limit percentage, simply press the ENTER button twice, then use the +/
–
buttons to increase/decrease the percentage accordingly.
Safety Timer
The Safety Timer offers another level of safety to help prevent dangerous over-charge that can
result in damage to the battery or fire causing damage and/or personal injury.
The safety timer
will limit the amount of time that a function can go on, and in the case of charging, it will end the
charge process when the time limit is reached even if the other functions (such as CHG End Voltage,
Capacity Limit, etc.) do not. To adjust the Safety Timer time limit from the minimum to the maximum
time allowed, simply press the ENTER button once, then use the +/
– buttons to increase/decrease the
time accordingly.
If most of your charging will be done at a 1C rate (typically requiring 45-75 minutes for an
approximately 70-90% discharged battery to be fully charged), we recommend setting the time to
approximately 90-100 minutes. However, please keep in mind that if the time limit is set too low that it
is possible the charger will end charging when it reaches the time limit rather than ending the charge
appropriately per the chemistry/type (i.e.
– delta peak for NiCd/NiMH, CC/CV to CHG End Voltage for
LiPo/LiIon/LiFe, etc.), especially if the battery was discharged further than expected and/or is charged
at too low of a current rate.
Temperature Cutoff
The Temperature CUTOFF is the internal temperature at which the charger will reduce the amount of
charging/discharging power or stop charging/discharging entirely, while remaining powered on, to
prevent permanent damage to the charger. However, in the event that the temperature exceeds the
cutoff, the charger will power down entirely. To adjust the Temperature CUTOFF simply press the
ENTER button twice, then use the +/
– buttons to increase/decrease the temperature accordingly.
Key Beep
The Key Beep setting allows you to turn the audible ‘beep’ associated with key presses ON or OFF.
To turn the beep ON or OFF simply press the ENTER button once then use the +/
– buttons to turn it
on or off accordingly.
End Beep Duration
The End Beep Duration setting allows you to set the duration of the audible ‘beeps’ associated with
the end of the charge, discharge, or other processes. To turn the beep OFF entirely, on for 5, 15, or
30 seconds, or ON indefinitely until you manually turn it off, simply press the ENTER button twice then
use the +/
– buttons to change the setting accordingly.
Temperature Unit
The Temperature Unit setting allows you to view the temperature readings found throughout various
screens in the charger in degrees Celsius or degrees Fahrenheit. To change the temperature unit
displayed simply press the ENTER button once then use the +/
– buttons to switch between the units
accordingly.
