As the battery nears full charge capacity, the unit's output will automatically drop
to a lower charge rate.
Pressing the 2/10/25 AMP button repeatedly advances to standby mode; the
unit sounds a beep, displays "000" and stops charging.
4. The battery charger displays the charge current. To view the battery voltage,
press BATTERY VOLTAGE button. The charger will sound a beep and display the
battery voltage for 3 seconds, then returns to displaying the charge current.
5. The display shows "FUL" when the battery is fully charged.
6. Follow the steps outlined in "Important Safety Instructions" at the front of this
manual to disconnect.
Automatic Float Charging
Automatic Float Charging is ideal for maintaining a fully charged battery.
1. Keep the AC power and battery connected after battery is fully charged.
2. The charger monitors the battery and tops it off as needed.
3. The Float Charge indicator lights and the display shows charge current when
topping off the battery and returns to "FUL" when completed.
4. To view battery voltage, press the Battery Voltage button.
Charging can be terminated by pressing the charge rate selector button at any
time when unit is charging. After AC power interruption, charging restarts at
2 amp rate automatically and the battery type will default to "GEL".
If battery size is not known, charge at the 2 amp rate. DO NOT
Equalizing is the process by which the fluid in each of a battery's cells is equalized.
This process occurs after charging is complete.
• NEVER TRY TO EQUALIZE A GEL OR AGM CELL. THE RESULTING
EXPLOSION COULD CAUSE PROPERTY DAMAGE, SERIOUS INJURY
• Remove or disconnect the vehicle's battery when equalizing.
The frequency which the equalization process needs to be run depends on the use of
the battery. The more the battery is used, the more undercharged it becomes; thus the
more frequently the battery should be equalized.
1. Do not use this mode on sealed or valve regulated batteries. This mode is only
meant for wet (unsealed/vented) batteries.
2. Make sure there are no flammable sources near the recharging sight.
3. Wear safety glasses, gloves and protective clothing.
4. Remove battery from vehicle. MAKE SURE THAT THE BATTERY HAS GOOD
VENTILATION. The process causes the release of hydrogen and oxygen. An
accumulation of these gases presents a real danger of explosion.
5. Open the battery cap, if removable.
6. Fill the battery with distilled water according to the manufacturer's instructions.
Since batteries may rapidly bubble while being charged, remember to refill (only
with distilled water) after the equalization process is complete and the voltage is
back to normal.
7. Follow the steps in the "Charging the Battery" section on page 5 of this manual.
8. Push the Battery Type Selector Switch until "WET" is displayed. (This mode will
only work if a WET battery is selected.)
9. Choose the correct charge rate and start charging. You can check the battery
voltage by pushing the Battery Voltage button. This will trigger the Battery Voltage
10. Push the Equalize button at any time and the battery will automatically begin to
equalize in 4 amp limited current. Note that in order to push the recessed button
you will need a small pin or ballpoint pen.
11. Every hour, the temperature should be checked by touching the battery. If the
battery is hot to the touch, stop the charging and allow the battery to cool.
12. The voltage rises, but does not go over 15.3v to 16.2v (2.55-2.7v per cell)
depending on ambient temperature, it will automatically adjust.
13. The "WET" LED flashes while the charger is in equalize mode.
14. The digital readout will show "FUL" when the equalization process is complete.
The Engine Start function can supply 75 amps for engine starting.
1. Set the 2/10/25 AMPS button to 25 amp mode and immediately press the 75A
button switch to activate the Engine Start mode.
2. The digital display will countdown from "999" to "000."
3. When the "000" count is reached and begins flashing on the Display, the vehicle
is ready to start.
4. Crank the engine using manufacturer's guidelines, typically in 3 to 5 second
bursts. The high current engine starting function requires a resting/cooling period
between tries. The charger will switch back to regular charge mode after
5 seconds and will not allow operation in this mode for 4 minutes. Wait 4 to 5
minutes before a second attempt at starting the engine, if needed.
5. During the rest period, the battery is charging at 25 amps. After engine starts,
follow the steps outlined in "Important Safety Instructions" at the front of this
manual to disconnect.
Whenever a lead-acid battery begins to discharge, lead sulfate, an insulator, begins
to build up on the battery's internal plates. This reduces the ability of the battery to
hold a full charge. When that battery has an immediate charge, most of the lead
sulfate is dissolved and the plates are free of this insulation. If a battery remains in a
discharged condition over a longer period of time, the lead sulfate changes to a hard
crystalline form, making a full charge difficult to achieve. Reconditioning may "save"
a sulfated battery.
BATTERY RECONDITION MODE should only be used with 10 Amp Hour (Ah) or
larger capacity lead-acid batteries. Charge the battery to be treated for 20 minutes,
