HITEC CG-330, CG-335 Instruction Manual

Instr uction Manual CG-330/CG-335

Congratulations on your purchase of the all new Hitec CG-330/335peak charger. The CG-330/335 is a very versatile
charger, incorporating a unique glow igniter battery charging feature and a

Boosted Charging Method that charges up

to 24 cells(28.8 Volts) from a 12 Volt source.

The CG-330/335 has many safety features to protect both the charger and the battery you are charging. Since this is a
high voltage charger with large capacity, improper usage can result in damaging the unit or your batteries so
understanding its proper usage is a necessity. Do not attempt to charge any batteries until you have read and
understood the instructions.

FEATURES

1

. Initial Cut-off Error Override:

When the subject battery is entirely drained, the initial charging amperage is very high. The batteries chemical balance
becomes unstable and causes voltage fluctuation and sometimes the charger will read this as a delta peak and stops
charging (false peak). You may mistakenly think the battery is fully charged and start using the battery, that can lead to
fatal results. Always check for false peak at least 3 minutes after charge cycle has started. The CG-330/335 employs a
3 minute cutoff override when the start switch is first engaged. The amperage adjustment knob must be adjusted within
the first 3 minutes after the start button is pushed. If the battery false peaks simply restart the charge cycle by pushing
the start button. Note: The battery will rarely false peak twice in a row. If the charger shuts off twice in a row and the
battery is warm, IT IS CHARGED.

2

. Low Battery Input Voltage:

Most chargers cannot be used when the source battery falls below 11 Volts. The CG-330/335 can operate without error
even when the input battery drops to 9 Volts. If it goes below 9 Volts, the source battery must be recharged before
further usage. Failure to do so may result in the source battery being damaged.

3

. Input Battery Polarity Protection:

A common error is to switch the polarity of the input battery.
There is a circuit to protect the charger from damage if this occurs.

4

. Output Battery Polarity Protection:

If you plug your subject battery backwards and push the start button, the charger will start blinking without engaging the
charging function.
This is true for both the glow charger and the 4-24 cell main charger. Correct the problem and restart.

5

. Charging Port Short Protection:

If the charging port is shorted out for any reason, the charger will start blinking. Correct the problem and restart.

INSTRUCTIONS FOR USE

1

. Glow Charger:

Simply connect your glow igniter battery to the glow jack.
There is no need to push the start button to engage the glow battery charging cycle, it will start automatically. When the
charging is complete, the charging indicator will automatically turn off and convert to trickle charging mode.
This is denoted by the LED light blinking.

2

. 4-24 Cell Charging:

This process is accomplished through the primary charging port.

(a) Connect the CG-330/335 to the 12V input battery.

(If a mistake is made and polarity is reversed, the warning LED will start blinking)

(b) Connect the subject battery to the charger through the primary charging port.

(If the polarity is reversed the reverse polarity LED will turn on)
(c) Turn the Amp knob to the minimum amperage. ( far left )
(d) Push the start button. Make sure the charging LED turns to green.
(e) Adjust the Amp knob to the optimum amperage position.

This must be done within 3 minutes from the start of the charge cycle.
(f) When the green LED turns off, charging is completed (The battery should be warm to the touch), leave it

connected and the trickle will engage automatically.

3

. Secondary Charge 4 cell Output:(CG-335only)

This output starts at 500mah and drops to 250mah charge as the battery nears full capacity. There is no automatic or
peak charge cut-off on the secondary charge port. It is recommended that this be used for no more than one hour at a
time. Remove pack from charge when cells get warm.

4

. Volt/Amp Select Button:(CG-335only)

If you wish to see the Amperage display on the screen, press the select button during the charge mixing.
IMPORTANT : Please disregard the displayed value of either the voltage or the ampherage, after the charging is
completed and turned to trickle charging (LED is blinking)

5

. Low Battery Warning Light:

GREEN

: Input battery is at full capacity.

Amber

: Source battery is low but the main charge of 4-24cell is unaffected.

Secondary 4cell charging(CG-335only) does not function properly at this stage.

Red

: All charging should be discontinued till the source battery is recharged.

RECOMMENDED CHARGE RATES(4-24cell charging only)

110mah-650mah: 0.5A- 1.0A
800mah-1100mah: 1.5A - 2.5A
1200mah-2000mah+: 3.0A - 5.0A
