The following features apply to NiCd and NiMH batteries only:

5. PEAK DELAY AT START: At the beginning of charge the voltage of NiCd and NiMH batteries can be somewhat unstable.

This could cause the peak detection circuitry to accidentally stop charge far too early, which would cause the battery to NOT

become fully charged. This peak delay function will temporarily turn off the peak detection circuit only during the very early

stages of charge to prevent this from happening. Select the number of minutes to temporarily shut off the peak detector at the

beginning of charge. A 3 to 5 minute delay is usually enough. Setting a delay time of 0 minutes turns this function off.

Note: Charge current will likely be lower than the setting during this time, which is normal.

6. DELAY BETWEEN CHARGE/DISCHARGE: This is a time delay designed to allow a battery to cool between charge and

discharge portions of a cycle. Select from 1 to 60 minutes. If the battery becomes too warm during a cycle, increase the

number of minutes on this screen to a higher value.

7. PEAK SENSITIVITY: When peak charging NiCd/MH batteries, Triton2 should see the battery's voltage increase to a

maximum level – or "peak". Then, the battery's voltage should actually drop very slightly. When the charger sees this, it should

stop charge completely. You can customize how closely Triton2 will try to detect this peak, which is called "peak sensitivity".

This value is set in milli-volts per cell in the pack. A higher mV number can result in less precise peak detections. A lower

mV number can result in more precise peak detections, but very low values (under 5mV) can sometimes result in erratic

operation (depending on the quality of the input power source, input and output connections, battery, etc.). Recommended

settings are 8-10mV for NiCd batteries, and 5-8mV for NiMH batteries.

The following features apply only to NiMH batteries:

8. NiMH MAX. CHARGE INPUT: This is another backup safety feature to protect NiMH packs. During charge, IF peak voltage

is not detected and the safety timer has not expired, this function will automatically stop charge when the amount of capacity

delivered to the battery matches the value set in this screen. Setting this number to 110% of the rated capacity of your battery

is recommended. For a 650mAh battery, 110% would be (650 x 1.1) 715mAh. The 110% value of a battery rated at 1800mAh

would be (1800 x 1.1) 1980mAh, etc. Setting a value of 9900mAh will effectively turn this feature off.

9. TOP-OFF CHARGE: When peak charge ends, delivering another short burst of charge will help to quickly maximize a NiMH

battery's voltage before trickle charge starts. T2 will deliver the amount of current set in this screen for 20 minutes only before

trickle charge starts. Set this screen to somewhere near 7% of the current set in the "NiMH CHARGE" screen. For example:

if the "NiMH CHARGE" current is set at 3.5 amps, set this screen to (3.5A x 0.07 = 0.245A) 200mA or 300mA. If the "NiMH

CHARGE" current is set to 850mA, set this screen to (850mA x 0.07 = 59mA) 100mA, etc. It's not critical to set this value with

extreme accuracy. This feature can be turned off by setting this screen to "None". "Top-off" will show on the display during top-

off charge, and "END" will show when complete (now in trickle charge).

Triton2 keeps track of various type of data in the Data View Menu as shown below, which can be viewed at any time.

WHILE a charge, discharge, or cycle is occurring, press BATT TYPE to find the Data View screens. Press MENU CHANGE

to return to the Main Menu.

BEFORE OR AFTER a charge,

discharge, or cycle, press BATT

TYPE

and

CHANGE

simultaneously to find the Data View

screens. Press MENU CHANGE to

return to the Main Menu.

To view capacity data for more

than one cycle, rotate the dial to

find the "Chg / Dsch" screen. The

number on the top line is the

cycle number. To view data for

any cycle, press the dial, then

rotate to find the cycle number

you wish to view. On the bottom

line, capacity measurements in

mAh are shown on the left for the

charge portion of the cycle, and

on the right for the discharge

portion of the cycle.

Press MENU CHANGE anytime

to return to the Main Menu.

PEAK: The highest or "PEAK" battery voltage measured during charge is shown at left.

AVE DSCH: The average voltage of the battery as recorded and calculated over the course

of one discharge, shown at right.

BATTERY CONDITION: Keeping track of these voltages over time can help to evaluate a

battery's overall condition as it ages. A battery's peak and average voltage levels will

gradually decrease as it reaches the end of its usefulness.
