6.2 “FAST” CHARGING A LITHIUM BATTERY.
When charging a Lithium battery, the charging current will
begin to drop as the battery reaches nominal voltage. By using
the FAST charge option, the reduction of power will not be as
great as it is with a standard charge. The benefit of this is a
reduced charge time. The drawback is that the pack will most
likely not charge to its full capacity.
Like a standard charge sequence, the value in the lower left
corner of the screen is the selected charge current, in the lower
right, the voltage of the pack that will be charged. To change
these values, press the START/ENTER key to cycle through
the adjustable settings. Use the increase/decrease buttons to change the values and use
the START/ENTER button to confirm the values set. When ready to FAST charge, press
and hold the START/ENTER button for 3 seconds to start the process. Note, when FAST
charging, the lower left corner of the screen will show “FAS” and not the selected charge
current.
6.3 “STORAGE” CHARGING A LITHIUM BATTERY
When a lithium battery will sit unused, for long periods of time, it is best to give that pack
a STORAGE charge. This will charge the battery to a nominal storage voltage (3.85V for
LiPo, 3.75V for Lilo and 3.3V for LiFe per cell). Storage mode will automatically determine if
the battery needs to be charged or discharged to reach this level. The balance plug of the
battery must be plugged into the charger for a proper storage charge to take place. Set the
charge current and the battery voltage/cell count as you would any other charge mode by
pressing the START/ENTER button to select the parameter you
wish to change, and use the INCREASE/DECREASE buttons to
adjust the value. When you wish to confirm your setting, press
the START/ENTER button. To initiate the storage charge, press
and hold START/ENTER for 3 seconds, confirm the cell count
selected is the same that the charger is indicating and press
and hold START/ENTER for 3 seconds to begin charging.
When charging, the screen provides useful information like the
charge rate, number of cells being charged, battery voltage
and the amount of mAh, or capacity that the charger has put
into the pack being currently charged. Press Batt type/Stop to
stop the charging process at any time.
