WARNING: BURST HAZARD:
• NEVER EQUALIZE A GEL OR AGM BATTERY, these may burst and cause SERIOUS INJURY and property
damage.
• 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 7 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 indicator.
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.
Engine Start
The Engine Start function can supply 110 amps for engine starting.
1. Set the 4/10/20/40 AMPS button to 40 amp mode and immediately press the 110A 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 4 amps. After engine starts, follow the steps outlined in
“Important Safety Instructions” at the front of this manual to disconnect.
Recondition Mode
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, before using RECONDITION Mode. Observe the
Digital Display for any codes. This initial charge will check the battery for shorted cells (F01), open cells (F03)
or battery too low to accept a charge (F02), and to ensure the battery can take a charge. If code (F03) is

Remove or disconnect the vehicle’s battery when reconditioning.
1. Make sure the charger is in initiation state with a circulating pattern on the display or in charge OFF mode
with “000” on the display. If not, press 4/10/20/40 AMP button repeatedly until “000” shows on the display.
2. Press the Battery Recondition button to start the process.
3. DES appears on the display for 3 seconds, then it changes to three horizontal moving bars.
4. The process takes 24 hours and stops automatically. The display shows “000” when complete.
Alternator Check
Part 1
No Load (Turn OFF all vehicle’s accessories): The battery must be fully charged before testing the alternator.
Run the engine long enough to achieve normal idle speed and verify there is a no-load voltage.
1. Press Alternator Check to start the check.
2. Alternator Good LED will light to indicate the alternator is good, or F07 will display to indicate the alternator
is out of typical voltage range.
3. Press Alternator Check again to stop the test.
Part 2
Under Load (Accessories ON): Next, load the alternator by turning on as many accessories as possible (except
for A/C and DEFROST)
1. Press Alternator Check to start the check.
2. Alternator Good LED will light to indicate the alternator is good, or F07 will display to indicate the alternator
is out of typical voltage range.
3. Press Alternator Check again to stop the test.
If the first alternator check indicates a good alternator and the second indicates the alternator is not good, the
problem could stem from: loose fan belts, an intermittent diode failure or possibly bad connections between the
battery and alternator and/or ground.
Notes: BATTERY VOLTAGE button is disabled in Alternator Check mode.
F07 may display because someone has added a number of accessory loads on the charging system, thereby
increasing current demand from the alternator. MAKE SURE THAT THE ALTERNATOR IS RATED TO SUPPORT
THE APPLICATION.
This check may not be accurate for every make, manufacturer and model of vehicle. Check only 12 volt systems.
APPROXIMATE CHARGING TIMES
The 40 Amp Smart™ Battery Charger will automatically adjust the charge rate as the battery becomes
charged, and stop when the battery is fully charged. Deep cycle batteries may require longer charging time.
For estimates of the time it takes to charge a battery, refer to the following table.

*NR = Not recommended at 4 amps — use a higher charge rate.
The times shown in the table above are approximate and refer to a 50 Ah automotive battery. For example, a 50
Ah (12 volt) battery is discharged (50%). How long should it be charged at the 10 amp rate? See the chart
above under “50%” and “at 10 amp rate.”
In most cases, battery charging times will vary depending on the size, age and condition of the battery. Smaller
batteries should be charged at a lower rate (4 amps) and an extra hour added to charge time.

F01 — Internal Shorted Cell Battery
If the battery being charged has an internal shorted cell, the F01 will show. We recommend taking your battery
to a certified automotive service center for evaluation.
F02 — Bad Battery Connection or Battery Voltage Too Low to Accept Charge
When F02 appears, the most common cause is poor connection to battery.
• Follow the steps outlined in “Important Safety Instructions” at the front of this manual to disconnect AC cord
and clamps, clean battery terminal and reconnect.
• If the situation persists, we recommend taking your battery to a certified automotive service center for evaluation.
F03 — Sulfate or Unchargeable Battery
Appears when the battery is highly sulfated and cannot accept normal charge current.
• Follow the steps in “Recondition Mode” to recondition the battery.
• Follow the steps in “Equalizing” to equalize the battery.
• If the situation persists after reconditioning and equalizing, we recommend taking your battery to a certified
automotive service center for evaluation.
F04 — Overtime Condition
Appears when charging time exceeds 18 hours. You may be using a charge current rate too low for a large
battery. Select higher charge rate to charge the battery.
F05 — Overheated Condition
The ventilation grill that prevents the air from flowing in and out of the charger may be blocked.
• Follow the steps outlined in “Important Safety Instructions” at the front of this manual to disconnect AC cord
and clamps, allow the unit to cool for 30 minutes and reconnect.
• Make sure there is ample ventilation before resuming operation.
F06 — Reverse Polarity
The connections to the battery’s positive and negative terminals are incorrect. Follow the steps outlined in
“Important Safety Instructions” at the front of this manual to disconnect AC cord and clamps and reconnect to
battery with correct polarity.
F07 — Alternator Voltage
Alternator output voltage is out of typical operation range.
Charging a Very Cold Battery
If the battery to be charged is very cold (in temperatures below freezing — 0°C/ 32°F), it cannot accept a high
rate of charge. The initial charge rate will be low. The charge rate will increase as the battery warms. Never
attempt to charge a frozen battery.
