1. To discharge a NiCd battery, press BATT TYPE to find the "NiCd

CHARGE" screen, then rotate the dial to find the "NiCd DISCHARGE"

screen, and skip to step 3.

2. To discharge a NiMH battery, press BATT TYPE to find the "NiMH

CHARGE" screen, then rotate the dial to find the "NiMH

DISCHARGE" screen.

3. Discharge current and cutoff voltage can be adjusted in the

discharge screens. Press the dial, then rotate to adjust the discharge

current value as desired (0.1 – 3.0 amps). See the included NiCd

AND NiMH CHARGE AND DISCHARGE CURRENTS chart for

recommended discharge current settings. Note: Rotating the dial

fully to either direction will cause "auto" to show. See the "Notes"

section below for details on this auto function.

4. Press the dial to cause the discharge cutoff voltage to flash. This

will be the voltage of the entire pack (not per cell) when discharge

will end. Rotate the dial to find the desired value, then re-press the

dial to confirm. See the DISCHARGE CUTOFF SETTINGS –

NiCd & NiMH chart at right for recommended cutoff voltage

settings. To measure how much TIME a battery can realistically,

safely power a transmitter or receiver, it's recommended to use

the "1.1V per cell" settings. Otherwise, to measure a battery's

ability to hold its manufacturer's rated capacity, or to measure how

much time a battery can realistically power an electric motor, use

the "0.9V per cell" settings. Note: Rotating the dial fully to either

direction will cause "auto" to show.

See the "Notes" section below for

details on this auto function.

5. To START DISCHARGE, press and

hold the dial for 2 seconds. "BATTERY

CHECK" will show briefly as T2 checks

the condition of the battery. Discharge

will start automatically if the battery is

in suitable condition, at which time

you'll see a screen like shown at right.

6. When discharge is finished, the screen will show "END" and tones will sound for 10

charged, or disconnected from Triton2. To see details about input, output, or average discharge voltages, press BATT TYPE

and MENU CHANGE buttons simultaneously to see the DATA VIEW screens (see page 12).

Notes about discharging NiCd and NiMH batteries:

• Some transmitters might contain a diode in their charge circuit which could prevent the Tx battery from being discharged through the radio's charge jack,

causing a "No battery" error to show. It's best to remove the battery from the Tx and connect it directly to Triton2 for discharging (see page 4 for a list of

adapters).

• 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 3 amps. For packs having more than 6 volts, the actual amount of discharge current might automatically be limited so

to not exceed the charger's maximum rated discharge power of 20 watts. See the included MAXIMUM POWER CHART for details.

• For batteries which are used in high current applications such as driving electric motors (not for Tx or Rx batteries), it's best to discharge down to 0.9V

per cell in the pack as shown in the DISCHARGE CUTOFF SETTINGS – NiCd & NiMH table. When discharged at high current, a battery's voltage will

drop more rapidly and this 0.9V discharge cutoff will allow Triton2 to more realistically simulate how long the battery will last during real use. Do NOT

attempt to discharge cells to voltages lower than recommended.

• For transmitter and receiver batteries, it's best to discharge down to 1.1V per cell in the pack as shown in the DISCHARGE CUTOFF SETTINGS – NiCd & NiMH

table. This will allow Triton2 to more accurately measure how many minutes a battery might SAFELY power a transmitter or receiver during actual use.

• After discharge, compare the final capacity measurement displayed to the capacity rating listed on the battery's label. If a battery provides less than 70%

of its rated capacity it may need to be replaced. Additional cycles can be attempted to try and revive the battery, but if capacity measurements fail to

improve the battery should be replaced.

• Discharge can be stopped manually by pressing MENU

• In the "auto" current setting, T2 will automatically set the appropriate discharge current based on the condition of the battery. It is NOT recommended to

use the "auto" function if charging smaller electric flight type NiCd / NiMH batteries (smaller than "AA" cells).

• There are two main reasons why someone would want to discharge a battery. First, to see if the battery is holding its rated capacity (see the CYCLING

NiCd AND NIMH BATTERIES section). Or, to see how much capacity remains in the battery after a flying session. This can help you gauge how much

energy your flight system is requiring from your battery.

• In the "auto" voltage setting T2 will automatically detect the number of cells in the battery, and then discharge the battery to 0.9V per cell in the pack.

Discharge current may vary when in auto mode, which is normal.

Discharge capacity: This is how much energy (capacity, in

"mAh") the battery delivered during discharge. When

discharge ends, this number could be low if the battery

previously had little charge. For a battery which

previously had been fully charged, this number should

ideally be within 10% of the battery's own mAh rating.

Elapsed discharge time: This is the number of minutes the

battery has been on discharge. When discharge is

finished, if the battery previously had little charge, this

number should be low. For batteries which previously had

been fully charged this number should be larger.
