Battery Percent and Charge Time

This charger adjusts the charging time in order to charge the battery completely, efficiently and safely. The microprocessor automatically performs the necessary functions.

Charge Rate – The charge rate is measured in amps. This charger provides charge rates of 4A, 20A and 70A. The 4A rate is for charging smaller batteries, such as those used for motorcycles and garden tractors. Such batteries should not be charged using the 20A or 70A rate. The 20A and 70A rates are for charging larger batteries. In the 20A and 70A mode, the charger begins at a low-charge rate and increases the charge rate if it is determined that the battery can accept the higher rate. All charging modes will decrease the charge current as the battery approaches maximum charge.

Automatic Charging Mode – When an automatic charge is performed, the charger switches to the maintain mode automatically after the battery is charged. For a battery with a starting voltage under 1 volt, press and hold for five seconds to start Automatic Charging, or use manual mode to pre-charge the battery for five minutes to get additional voltage into the battery for the charger to analyze.

Aborted Charge -If charging cannot be completed normally, charging will abort. When charging aborts, the charger’s output is shut off, the CHARGING (yellow/orange) LED will go out and the digital display will show « bAd bAt ». The charger ignores all buttons except in that state. Press to reset after an aborted charge.

Desulfation Mode

If the battery is left discharged for an extended period of time, it could become sulfated and not accept normal charge. If you select , the charger will switch to a special mode of operation designed for sulfated batteries. For the best performance, AUTOMATIC CHARGE Mode is recommended for Desulfation Mode. If successful, the charger will fully desulfate and charge the battery, and then the green LED will light. Desulfation could take up to 10 hours in AUTOMATIC CHARGE mode. If desulfation fails, charging will abort and the charger will go into Abort Mode. If MANUAL CHARGE mode is selected and the timer is set to between 10-120 minutes, desulfation will stop at the specified time. If the timer is set to HOLD, the maximum time for desulfation will be 10 hours.

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. If you are charging a deep cycle battery, the CHARGED LED comes on when the battery is charged enough for normal use.

Maintain Mode

3. Press to turn on the output.

4. When finished with Flash Reprogramming, press to exit this mode.

Using the Battery Voltage Tester

Overview

This battery charger has a built-in voltmeter to measure your battery’s voltage. The charger does not have a built in load tester. As such, a recently charged battery could have a temporarily high voltage due to what is known as “surface charge”. The voltage of such a battery will gradually drop during the period immediately after the charging system is disengaged. Consequently, the tester could display inconsistent values for such a battery. For a more accurate reading, the surface charge should be removed by temporarily creating a load on the battery, such as by turning on lights or other accessories for a couple of minutes before you read the display.
Read it a couple of minutes after you have turned the headlights off.
Testing Sequence: There are seven basic steps required to test the battery state of charge:
NOTE : You cannot test the battery voltage while charging.

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.
3. The CONNECTED (yellow) LED will light if a properly connected battery is detected.
4. Confirm the CHARGING (yellow) LED is off.
5. Set the DISPLAY to VOLTS.
6. If the output is on, press . If the output is already off, do not press .
7. Read the voltage on the digital display.

General Charging Notes

Fans : The charger is designed to control its cooling fans for efficient operation. Consequentially, it is normal for the fans to start and stop when maintaining a fully charged battery. Keep the area near the charger clear of obstructions to allow the fans to operate efficiently. NOTE: The charger has thermal protection, and it will shut down if it gets too hot.
Voltage : The voltage displayed during charging is the charging voltage and is usually higher than the battery’s resting voltage.

CALCULATING CHARGE TIME

1. Use the following table to more accurately determine the time it will take to bring a battery to full charge. First, identify where your battery fits into the chart.
2. NR means that the charger setting is NOT RECOMMENDED.
3. Find your battery’s rating on the following chart and note the charge time given for each charger setting. The times given are for batteries with a 50 percent charge prior to recharging. Add more time for severely discharged batteries.

MAINTENANCE INSTRUCTIONS

1. Before performing maintenance, unplug and disconnect the battery charger (see sections 5.8 and 6.7).

2. After use, unplug the charger and use a dry cloth to wipe all battery corrosion and other dirt or oil from the terminals, cords, and the charger case.

3. After every 100 hours or whenever you see dust accumulating on the fan blades, you should clean both fans using compressed air (as shown).
   NOTE : Use the compressed air on the fan blades only. Do not blow dirt into the fan shaft or bearing. These fans push a lot of air and are precision balanced. Excessive dirt and grime build up will cause the fan to be unbalanced and wear out quickly. If the fans fail, the charger may overheat and the thermal protection of the charger will shut it down.

4. Ensure that all of the charger components are in place and in good working condition, including the plastic boots on the battery clips.

5. Servicing does not require opening the unit, as there are no user-serviceable parts.

MOVING AND STORAGE INSTRUCTIONS

1. If the charger is moved around the shop or transported to another location, take care to avoid/prevent damage to the cords, clips and charger. Failure to do so could result in personal injury or property damage. DO NOT store the clips on the handle, clipped together, on or around metal, or clipped to cables.
2. Store the charger unplugged. The cord will still conduct electricity until it is unplugged from the outlet.
