FEA TURES

• AC/DC Delta Peak charger with MicroPeak Technology

• LCD displays five readings: Battery Status, Battery Voltage (V), Charge Current (A),

Charging T ime in minutes (Min), and Delta Peak Voltage Threshold in millivolts (mV)

• Charges Nickel Cadmium and Nickel Metal Hydride batteries

• For 3~8 cell AA and sub-C packs, plus a special setting for single cell “Glow Driver”

battery (single-cell)

• Nine charge current rates:

0.5Amp to 4.5Amp with 0.5Amp increments

• Fourteen delta peak voltage thresholds:

5mV to 70mV with 5mV increments

• Plug ‘n Play Operation for sub-C or larger battery cell(s)

• 12-bit Analog to Digital Converter greatly improves measurement resolution

• Digital Signal Processing (DSP) filters out noise and provides greater measurement

accuracy

• Compact size to fit into a field box

PLUG N’ PLAY INSTRUCTIONS for sub-C or larger battery cell(s)

1. Connect the charger to a power source (120V AC or 12V DC).

2. Attach the battery to the charger. The battery’s voltage will appear on the screen.

3. The charger has a default charge rate of 3.0 Amps. Press the start button to begin
charging if this is the intended setting. See ADVANCED INSTRUCTIONS section to
change the charge current rate.

4. The first 30~60 seconds is the battery diagnostic period. LCD will display “test” and
the red light will flash during this period. The unit will not accept new commands during
this diagnostic period.

5. LCD will display “Charge” and the red light will remain on during fast charge. The
battery status and voltage are displayed.

6. The charge rate, time and voltage can be viewed by pressing the “Display” button.

NOTE: If the delta peak voltage threshold has not been set manually, ignore the display
for the delta peak voltage threshold. The value displayed is irrelevant.

7. Charging can be stopped at any time during the charge cycle by pressing the “Start”
button.

8. When the fast charge cycle is complete, the unit will beep three times and automatically
begin a 50-minute 0.1 Amp trickle char ge cycle. During the trickle charge cycle “Charge”
and the red light will blink (with very short on time and long off time). After the trickle
cycle, the charger will automatically go into sleep mode.

9. Under normal ambient conditions, this charger stays cool and can continue to charge 3 to
4 batteries consecutively . After several consecutive charges, the protection circuit may
activate to prevent the unit being damaged. When this happens, please disconnect the
charger from the power source and allow the charger to cool down.

10. The LCD screen will become unclear if the unit is excessively hot. Please stop using the
charger if the LCD screen becomes unclear and allow the unit to cool.

11. “Err” displayed at any time indicates an error has occurred.

Example: If the charger is not corr ectly connected, “Err” message may appear.
