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
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.
Percent of charge |
|
|
|
|
|
in battery | 75% | 50% | 25% | 0% | |
at 4 amp rate | 3.5 HRS | 7.0 HRS | 10.5 | HRS | NR* |
at 10 amp rate | 1.4 HRS | 2.8 HRS | 4.2 | HRS | 5.5 HRS |
at 20 amp rate | 1.0 HRS | 1.5 HRS | 2.1 | HRS | 2.8 HRS |
at 40 amp rate | 1.0 HRS | 1.2 HRS | 1.7 | HRS | 2.2 HRS |
*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.
