Desulfation Mode
Activation of the special Desulfation Mode is indicated by the CHARGING (yellow) LED blinking. If successful, normal charging will resume after the battery is desulfated. The CHARGING (yellow) LED will then stop blinking and stay lit. Desulfation could take up to 8 hours. If desulfation fails, charging will abort. See Aborted Charge section.
Completion Of Charge
Charge completion is indicated by the CHARGED (green) LED. When lit, the charger has stopped charging and switched to the Maintain Mode of operation.
Maintain Mode (Float-Mode Monitoring)
When the CHARGED (green) LED is lit, the charger has started Maintain Mode. In this mode, the charger keeps the battery fully charged by delivering a small current when necessary. The voltage is maintained at a level determined by the BATTERY TYPE selected.
NOTE: The maintain mode technology utilized in Schumacher’s chargers allows you to safely charge and maintain a healthy battery for extended periods of time. However, problems with your battery, electrical problems in your vehicle, improper connections or other unanticipated conditions could cause excessive current draws, as such, occasionally monitoring your battery and the charging process is recommended.
Using the Battery Voltage Tester
(Models
1.With the charger unplugged from the AC outlet, connect the charger to the battery following the instructions given in Sections 6 and 7.
2.Plug the charger AC power cord into the AC outlet, following the instructions given in Section 8.
3.If necessary, press the BATTERY TYPE button until the correct type is indicated.
4.Read the voltage on the digital display or press the Display Mode button to set the tester to BATTERY % to read the voltage as a percent of charge.
Tester and Charger: When first turned on, the unit operates only as a tester, not as a charger. To continue to use it only as a tester, avoid pressing the CHARGE RATE button. Selecting a charge rate activates the battery charger and deactivates the tester.
Tester without Time Limit: If either the DISPLAY MODE or BATTERY TYPE button is pressed within the first 10 minutes after the battery charger is powered up, the unit will remain a tester (not a charger) indefinitely, unless a charge rate is selected.
Testing After Charging: After the unit has been changed from tester to charger (by selecting a charge rate), it remains a charger. To change the battery charger back to a tester, press the CHARGE RATE switch until all charge rate LED’s are off.
12.CALCULATING charge time
Find your battery’s rating on the chart on page 7, and note the charge time given for each charger setting. The times given are for batteries with a 50% charge prior to recharging. Add more time for severely discharged batteries.
CCA = Cold Cranking Amps RC = Reserve Capacity Ah = Amp Hour
NR means that the charger setting is NOT RECOMMENDED.
13.MAINTENANCE INSTRUCTIONS
13.1After use and before performing maintenance, unplug and disconnect the battery charger (see sections 6, 7 and 8).
13.2Use a dry cloth to wipe all battery corrosion and other dirt or oil from the battery clips, cords, and the charger case.
13.3Ensure that all of the charger components are in place and in good working condition, for example, the plastic boots on the battery clips.
13.4Servicing does not require opening the unit, as there are no
13.5All other servicing should be performed by qualified service personnel.
