2. Charge current: Move the cursor down to the "chg current" line. Press the dial, then rotate to find the desired charge
current. Re-press dial to confirm setting.
3. Discharge current: Move the cursor to the "dchg current" line. Press the dial, then rotate to find the desired discharge
current. Re-press dial to confirm the setting. If current is set to 10A or less, current will be drained from the battery in a 100%
linear configuration.
The TC-1030 also offers unique non-linear discharge currents of 20A and 30A for NiCd and NiMH packs only. Here, the battery
is discharged for 2 seconds at the selected current, then discharge is paused for 4 seconds. This process is repeated until the
battery reaches discharge cutoff. These settings are for conditioning of competition level racing packs, to lower a battery's
internal resistance and improve the battery's average discharge voltage. These settings are NOT functional with NiCd/MH
batteries having more than 6 cells. Refer to the notes at the end of this section for more details.
4. Peak sensitivity (NiCd and NiMH batteries only): This feature determines the accuracy of the peak detection circuit. The
adjustable range for NiCd batteries is 5-25mV (8-10mV is recommended). For NiMH batteries the range is fully adjustable from
0mV ("ZEROpk") to 15mV. Some racers prefer 1mV or 2mV settings. See the notes section for further details.
5. Discharge cutoff voltage: This is NOT the discharge cutoff voltage for the ENTIRE pack. Instead, set the voltage level
for EACH CELL in the pack where discharge will stop. See the notes section for more details.
6. Trickle charge current (NiCd and NiMH batteries only): This is the amount of trickle charge current that will be applied
to the battery only after peak charge has ended (not after discharge or cycling). See the notes section for further details.
7. Cutoff temperature: When used with the optional Team Checkpoint Temperature Sensor (TCPP9101), this charger can
monitor the temperature of the battery connected at the outputs. Monitoring a battery's temperature in addition to its voltage
can allow the charger to provide the most accurate full charges without damaging the battery, and is STRONGLY
recommended for use with LiPo/Ion batteries. Refer to the notes that follow for details how to use this function. Otherwise,
skip to #8.
• Do not connect a sensor to the charger if you do not wish to use the sensor.
• See the User Setup Menu to change the temperature scale between Celsius and Fahrenheit.
• The maximum recommended temperature for NiCd batteries is 113-130
• The maximum recommended temperature for NiMH batteries is 110-125
• NiCd and NiMH cells which are "AAA" size or smaller should use lower temperatures. For best results, start with lower
temperatures first, then if needed adjust this value upwards in small increments and closely monitor the charge progress.
• For LiPo/Ion batteries, exercise great caution! The maximum temperature for LiPo/Ion cells should not exceed 90-95
o
(32-35 C). Start with lower temperatures first and if necessary adjust the temperature setting as needed in small
increments and closely monitor the charge progress.
• If the battery reaches the max. temperature setting during charge, the charge process will completely stop and will not
re-start. Setting the temperature value too low may cause the charge process to stop too early, before full charge has
occurred. If so, increase the temperature setting by a small amount, making sure not to allow the battery to overheat.
Setting the temperature value too high may cause the battery to overheat. If so, decrease the temperature setting.
• If the battery reaches the max. temperature setting during discharge, discharge will temporarily pause to allow the
battery to cool to a safe temperature. Discharge will automatically resume when the battery's temperature drops by about
o o
4 F (2 C).
8. Number of cycles (NiCd and NiMH batteries only): This is the number of times the charger will automatically perform a
charge-to-discharge or discharge-to-charge cycle. See "Cycle Mode" below for how to set which function to perform first.
9. Cycle delay (NiCd and NiMH batteries only): This is a time delay that will occur between charge and discharge during
a cycle, designed to allow the battery to cool.
10. Cycle mode (NiCd and NiMH batteries only): This sets the pattern in which cycles are performed. Select either to
charge the battery before discharge (C>D), or to discharge before charge (D>C).
11. Maximum charge capacity: If the charger fails to detect full charge, this setting will automatically stop the charge process
when a certain amount of energy has been delivered to the battery. Instead of setting an actual capacity value, set the percent
of full capacity. For example: if the battery capacity entered in 1.c. on page 5 was "4200" and if the value set in this screen is
"110%", charge will stop automatically when (4200 x 110%) 4620mAh is delivered to the battery. For LiPo/Ion batteries the
recommended maximum value is 105-110%. A secondary use for this feature is to prepare batteries for extended-term
storage. Cell manufacturers recommend applying a partial charge to batteries before being put in storage. For such uses, it's
recommended to set this value to 30% for NiCd/MH batteries, and to 10% for LiPo/Ion batteries.
