LENGTH OF CHARGE
21.
a.
Test the battery for state of charge. Do not charge if it is over 75% charged or the battery is determined to be defective.
b.
Set beginning amps charge rate for size of battery and state of charge per charts
c.
Charge for length of time per charge,
d.
Discontinue charge when the specific gravity of electrolyte reaches 1.260 or above. A temperature compensating hydrometer
should be used for this reading. Discontinue charge if the battery begins to gas excessively or if the temperature of the electrolyte
reaches approximately 125°F. Do not overcharge batteries. Overcharging results in excessive water loss and eventual damage to
the battery.

ASSEMBLY INSTRUCTIONS
Attach the handle to the charger using the four screws provided.
OPERATING INSTRUCTIONS
CAUTION
- This battery charger must be fully assembled before operating. Failure to do so may result
in risk of injury.
USE OF INSTRUMENT PANEL:
The MINUTES CHARGE timer has an OFF position, a CONTINUOUS CHARGE position and a timed
charge range from 0 to 120 minutes.
a. OFF - Always make sure the timer is in the OFF position before connecting or disconnecting the clamps
from the battery. The charger will not charge with the timer in this position.
b. CONTINUOUS CHARGE - This position is used for slow charging or parallel charging and will not turn
the charger off. Do not use this position for fast charging.
c. 0 to 120 MINUTES TIMED CHARGE - The timer will automatically turn the charger off at the end of the
pre-set charging time. Turn the timer past 20 before setting the desired time.
TO CHARGE BATTERIES
Make connections to the battery per the instructions in preceding section of this manual. Determine if the battery is 6, 12, or 24 volts and
then set switch to 6V for a 6 volt battery, 12LO or 12HI for a 12 volt battery, or 24V for a 24 volt battery. Turn the timer on. If a higher
rate of charge is desired, advance switch to get desired rate. Set the timer to the desired minutes charge.
BOOST STARTING
Turn off all lights and accessories in the vehicle.
Connect the charger to battery per previous instructions. Fast charge the battery in HI position at least five minutes. Make sure the
battery is accepting current. Start the car with the charger connected to the battery. Follow the duty cycle on the unit. NOTE: Do not
crank engine more than 20 seconds in any five minute period. While waiting for starter to cool, allow the charger to continue to charge the
battery. Turn the switch to OFF and remove the AC power cord from the electric outlet before disconnecting the DC clamps.
CHARGING SULFATED BATTERIES
If your battery has sat in the discharged state for an extended period of time, it can become SULFATED. This usually is seen as a white
deposit near the top of the battery. The sulfate is formed when a battery with low water levels remains discharged for an extended time.
Sulfated batteries exhibit the characteristic of accepting no charge regardless of the rate of charge.
The charging method is two staged. The first stage of attempting to break down the sulfation to allow the battery to accept a charge must
be closely watched to avoid excessive charge rates as the battery begins to charge and overheat. The second stage is a slow charging
to restore the battery to full charge.
READ AND FOLLOW ALL PRECAUTIONS AND WARNINGS IN YOUR INSTRUCTION MANUAL BEFORE ATTEMPTING TO CHARGE
SULFATED BATTERIES. FAILURE TO OBSERVE THESE WARNINGS MAY RESULT IN PROPERTY DAMAGE OR SERIOUS
PERSONAL INJURY OR DEATH.
To recharge a sulfated battery:
1.
Attach the battery clamps as described in the instruction manual.
2.
Always use the charger's lowest rate when turning the charger on. Set the charger to the charger's highest rate for the voltage
of the battery being charged.
