Charging batteries – Great Planes Triton Charger - GPMM3150 User Manual

BATTERY MEMORIES: Triton includes memory locations for storing specific

parameters for up to 10 different batteries. When the “Memory (10) NiCd” screen is
shown, press the dial briefly to cause the memory number within the parentheses to
flash, then rotate the dial to scroll through other battery memory locations. When the
desired memory is found, re-press the dial to confirm the selection. Next, rotate the
dial to scroll vertically through the following screens for the selected memory: battery
type, number of cells, battery capacity, charge current, discharge current, and
discharge volts/cell. Adjust any such parameter as needed to match the battery type.
When the desired battery memory has been properly adjusted / selected, press MENU
and Triton will automatically return to the appropriate “charge” screen for the battery
type selected. Starting any function cannot be accomplished in the battery memory
screens. Triton must be in one of the screens described in points 2 and 3 above to
start any function. Note: It is not necessary to program batteries into memory. This
is merely a convenience if you do not wish to re-configure the charger each time you
change batteries.

ADJUSTING VALUES: To adjust a value in any screen, briefly press the dial and

the adjustable parameter will flash. Rotate the dial to adjust the parameter to the
desired value. Re-press the dial to confirm the selection (will stop flashing). If two
adjustable parameters show on a single screen, repeatedly press the dial to select the
appropriate parameter to be adjusted.

STARTING A FUNCTION: To start the function which is displayed on-screen

(except while in the “Battery Memory” screens), press and hold the dial (do not rotate)
for 2 seconds. Triton will perform a brief “Battery Check” to ensure the battery is in
suitable condition before proceeding.

Carefully read the following sections for detailed descriptions for all functions within
the MAIN MENU. Pressing both the MENU and BATT TYPE buttons simultaneously
at any time while in the MAIN MENU will jump to the DATA VIEW MENU.

“NiCd charge” and “NiMH charge:” Triton utilizes the “zero deltaV” peak detection
method to charge NiCd and NiMH batteries with linear current. This method can
result in a battery safely reaching 95 to 98% full charge, after which time Triton will
automatically switch to a gentle trickle charge current. Trickle charge will help the
battery safely reach its 100% full charge potential.

Triton will supply trickle charge current to NiCd and NiMH batteries only after an
individual peak charge – not after discharge or cycle. Trickle charge rates vary from
0 – 250mA, and are automatically set by Triton (not user adjustable). The trickle
charge rate is based on the fast charge current setting and the condition of the
battery being charged, and should be as follows:
