the charger is in the 40 amp charge mode; set the 4/10/20/40 amp button to 40 amps first to activate this button.
Battery Recondition is an automatic mode that, once started, continues for 24 hours and then stops. A series
of electrical pulses breaks the crystalline form of lead sulfate to return these chemicals into useful battery
electrolytes. More than 24 hours may be needed to restore. Periodic reconditioning is recommended to
maintain a battery's optimum performance. However, if 5 cycles does not improve battery performance,
discontinue and recycle the battery.
Battery Voltage (Alternator Voltage Check) is a quick check that measures the battery voltage. This check
is repeated at various electrical load levels and the tests allow the user to determine if the alternator can keep
up with the loads.

Equalizing is the process by which the fluid in each of a battery’s cells is equalized. This process occurs after
charging is complete.
2:54 PM
Page 8
• NEVER EQUALIZE A GEL OR AGM BATTERY, these may burst and cause SERIOUS INJURY and property
• 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

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
displayed, change to the BATTERY RECONDITION MODE.
2:54 PM

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
This check may not be accurate for every make, manufacturer and model of vehicle. Check only 12 volt systems.
The 40 Amp Smart™ Battery Charger will automatically adjust the charge rate as the battery becomes

attempt to charge a frozen battery.
