Great Planes Triton Jr. Charger - GPMM3152 - Manual (Page 16)

1. At the “LiPo CHARGE” screen (or “Li-Ion CHARGE” screen if
you selected that lithium type), press the down arrow once to
find the “LiPo DISCHARGE” screen (or “Li-Ion DISCHARGE
screen if you selected that lithium type).
2. Two values can be adjusted on this discharge screen. Press ENTER to cause the discharge current value to flash. Press INC+ or
DEC- to change this value (0.10 – 1.0 amps). Note: “0.1A” is the same as 100mA. “0.8” is the same as 800mA, etc.
3. Press ENTER to cause the discharge cutoff voltage value to flash. This is the voltage where Triton Jr. will stop discharging
the battery, and is based on 3.0V per cell. So the cutoff voltages should be 3.0V for a 1-cell battery, 6.0V for 2-cell packs,
9.0V for 3-cell packs, and 12.0V for 4-cell packs. Press INC+ or DEC- to adjust this value as needed. Press ENTER, or wait
5 seconds and Triton Jr. will automatically confirm both settings.
4. To START DISCHARGE, press and hold START for 2 seconds. “BATTERY CHECK, PLEASE WAIT…” will show briefly, and
Triton Jr. will start discharging if the battery is in suitable condition.
5. When discharge is finished, the screen will show “END” and tones will sound for 10 seconds. The battery can now be re-
charged, or disconnected from Triton Jr. Other data measured during discharge can be viewed in the DATA VIEW screens
shown on page 20.
Never attempt to care for lead-acid (Pb) batteries in the same way as other battery types! Lead-acid batteries commonly used
in R/C hobby field boxes require unique care and handling methods as they contain different characteristics than other battery types.
• Do not attempt to use the NiCd, NiMH, or lithium functions on Pb batteries.
• Do not exceed 14.7V maximum charge voltage for batteries rated at 12V.
• Pb batteries have a self-discharge rate of 5-10%, meaning they hold charge very well. Thus, there is no need to trickle
charge Pb batteries. No cycling of Pb batteries is needed.
• Do not leave Pb batteries in the full discharge condition, which could cause the battery to lose its ability to regain full charge.

NOTES FOR DISCHARGING LiPo AND Li-Ion BATTERIES
• For more accurate discharge readings, it’s better to use a current which
can discharge the pack in 1 or 2 hours.
• The maximum discharge current is 1 amp. Maximum power dissipation
during discharge is 5 watts, which might cause discharge currents to
automatically be limited for packs having high voltage.
