TIMER
The timer is designed to allow the battery to be charged for a desig- nated amount of time. To accurately charge your battery, you must know the size of the battery in ampere hours or reserve capacity in units, as well as the state of charge. Since this information is not known by the charger, the timer limit is set at 2.25 hours to prevent the battery from overcharging to a point where it can be severely damaged. If you do not know the charge state of your battery, set the timer at one hour or less, or use the automatic setting.
To set the timer:
1.Press the symbol for less time and the symbol for more time.
2.The Timer LED will light and digital display will show the time in minutes.
3.To turn the timer off, press the symbol until the digital display reads OFF.
TIMER HOLD
The Timer Hold feature overrides the timer allowing the charger to continue charging for over 2.25 hours. This feature is most often used when the charging rate is 2 or 20 amps. Using this feature requires closely monitoring the charge time and turning off the charger when the battery is fully charged.
Note: When the battery is fully charged, the charger and timer will not automatically turn off. It is important to monitor the charge level. Not doing so may cause damage to your battery.
To activate the hold feature:
1.Press the symbol until the Digital Display reads HLD.
2.To release the Timer Hold, press the until the digital display reads OFF.
Automatic Feature
In automatic mode, the charger will stop when the battery is fully charged. After charging is complete, this unit will maintain the battery at 13.4 Volts to prevent self discharge. To activate the automatic feature, first connect the clips to the battery and select the desired charge rate. Then, press the symbol once and “Aut” will be shown on the display. When charging is complete, the bat- tery % will show “100”.
BATTERY TEST
The Battery Test is based on the terminal voltage of the battery. If the battery is installed in the vehicle, make sure the engine and all accessories are turned off before testing.
1.Plug the power cord into a
2.Press the SELECT DISPLAY MODE button and select BATTERY %.
3.Hook the battery clamps to the battery as outlined in “Charging Your Battery” on page 3.
4.The digital display will show the charge % of the battery:

BATTERY/ALTERNATOR TEST
1.Plug the power cord into a
2.Press the SELECT DISPLAY MODE button and select
VOLTAGE. (The digital display will show the voltage of the battery.)
3.Hook the battery clamps to the battery, as outlined in “Charging Your Battery” on page 3.
4.Start the engine and while it is at a fast idle, read the digital display.
Note: The battery should be in a good state of charge before doing this test.
| 12V Alternator/Generator Display | ||
15 volts or more | = See vehicle owner’s manual | ||
15 | – 14 volts | = | Good condition |
14 | - 12.8 volts | = See vehicle owner’s manual | |
12.8 or less volts | = | Check with qualified technician | |
Note: If the digital display reads less than 12.8 volts, the charging system may have loose fan belts, a defective voltage regulator or alternator. Additional tests may be required to find the exact cause. Take the vehicle to a qualified service center.
select CHARGE RATE
The SELECT CHARGE RATE allows you to select the correct battery voltage and amp draw rate to match your charging needs. Read the following operating instructions for making the proper settings for charging a battery.
When you first start charging a battery, the amp reading will be high. As the battery becomes charged, the reading will decrease.
To determine the amount of amps being drawn by the battery:
1.Press the Select Display Mode button until the AMPS LED lights.
a.When the 55A setting is used, the charger switches between 55A boost mode and 10A mode. You should use a lower charge setting if the voltage reading is “OL” or is reading higher than 14.2 Volts for more than 3 minutes.
b.When charging at 20 amps, the display should show 15 amps for a discharged battery and
c.At the 2 amp charge rate, little or no display change will occur.
Note: The digital display will read OL or Overload if more than 55 amps are supplied to the battery. Overload means too high a charging rate. Lower the charging rate to continue.
To determine an accurate reading of your battery’s voltage before you charge:
1.Plug the power cord into a
2.Press the select Display Mode button so the VOLTAGE LED lights.
3.Connect the battery charger as outlined in “Charging Your Battery” on page 3. The voltage will be displayed.
Note: If a battery has recently been charged or in a vehicle that has been run recently, turn on the vehicle’s headlights for a few minutes before reading the meter to avoid getting a false reading from a surface charge.
