three times to fi nd the VIEW DATA screens. The charger can display several types of
input, output, and battery data in these screens, as follows:
1. Press
T
to fi nd the INPUT V screen. This is the DC voltage measured on the charger’s input. Even if connected to an
AC input, that voltage is converted to a DC voltage inside the charger and will be displayed in this screen.
2. The OUTPUT V screen shows the DC voltage measured on the charger’s output.
3. The PEAK V screen shows the highest measured battery voltage during the last charge.
4. The CAPACITY screen shows how much charge energy was delivered to the battery during the last charge.
5. The CHG TIME screen shows how many minutes the charger delivered a charge to the battery. This does not include
any time that a trickle charge was delivered.
6. Press

to return to the START screen.
STARTING CHARGE
1. Press
X
until the START screen is found.
This screen must be showing in order to start a charge.
2. Press and hold the START button for 3 seconds to start charging the battery. The charger will then display several
types of information during the charge process like shown below:
For
NiCd
and
NiMH
batteries
, a linear charge current will be delivered to the battery. The peak detection method will be
used to accurately look for the highest battery voltage during charge. Once this is detected, the charger will automatically
stop fast charge and go to trickle charge mode.
Caution:
Make sure the charge current setting is safe for your battery to prevent overheating of the cells. “AAA”, “AA”,
“A”, and “2/3A” size batteries generate heat more quickly than large sub-C batteries. Most radio batteries should NOT be
charged at currents greater than 1.5A. Failure to follow this recommendation could permanently damage your battery.
The constant-current / constant-voltage (cc/cv) method is used to fully charge
lithium batteries
. This method is much
different than the peak detection charge method for NiCd batteries. In the early stages of charge, the charger will attempt
to deliver the set amount of current to the battery –
unless
the charger determines that the current should be reduced
based on the condition of the battery. Later, after the battery reaches a certain voltage per cell (4.10V for LiPo, 4.00V
for Li-Ion, and 3.50V for LiFe), the charger will stop trying to force the current at a constant level and instead apply a
constant voltage.
You will see a considerable reduction in output current at this time. This is normal.
When current
to the battery drops to approx. 80-100mA, the charger will automatically stop charging the battery.
When the “CHG Volt” screen shows the voltage of the battery during charge, the loading affect of the charger will skew
the voltage reading of the battery, which is normal. A higher current will skew the reading more than a smaller current.
Voltage readings taken when charge is fi nished will more accurately show the true voltage of the battery.
To manually stop a charge while in progress, either disconnect the battery from the charger, or press START.
