to  nd the desired battery type. Press CHANGE to con rm the new setting.
WARNING! NEVER set the BAT.TYPE screen to a type that does not match your battery! For example,
accidentally charging a LiPo battery in the NiCd setting could result in an overcharge condition on
the battery, which could result in an intense FIRE!
4. Press
to  nd the CELL screen, to set the number of cells / nominal rated voltage of the battery. The number of
cells in the pack is shown on the top line, and the nominal rated voltage of the pack will show on the bottom line.
Press CHANGE to cause the setting to  ash, then press (+) or (–) to  nd the setting which matches your pack Press
CHANGE again to con rm the new setting.
WARNING! For LiPo and LiIon batteries, NEVER set the voltage to a value which is higher than the
rated voltage printed on the battery! Attempting to charge such a battery to a voltage that is higher
than its rating could result in an overcharge condition on the battery, which could result in a very
intense FIRE!
5. Press
to  nd the CAPACITY screen. If the charger fails to detect full charge, this function can stop the charge
process after a certain amount of energy (mAh) has been delivered to the battery. This protects the battery from
accidental overcharge.
WARNING!! For LiPo, LiIon, and LiFe cells, always set the value in this screen to the exact rated
capacity of the battery (or as close as possible). Lithium battery types can EASILY BECOME
DAMAGED if overcharged and possibly START A FIRE! NEVER set the number in this screen to a
value higher than the capacity (mAh) value printed on the lithium battery.
Setting this screen to 110–130% of a NiCd or NiMH battery’s rated “mAh” value is recommended. As shown in the
quick reference chart on page 6, locate the rated capacity of your battery in the left column, then  nd your battery’s
110% or 130% capacity value to the right. Enter the desired capacity value into this screen.
Press CHANGE to cause the setting to  ash, then press (+) or (–) to  nd the proper capacity value (as close as
possible). Press CHANGE to con rm the new setting.
6. Press
to  nd the fast charge CURRENT screen:
a. For lithium based batteries, the charger will automatically set the charge current to a value of 1C (based on the
value entered in the CAPACITY screen described above). This can be overridden manually.
