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 or 12 volts and then set switch to 6 VOLT or 12 LO respectively. 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.
CAUTION:
NEVER CHARGE A BATTERY AT VOLTAGE RATES ABOVE THAT OF THE BATTERY.
3.
The battery will show little or no amperage at the start of the charging process. This will continue until the sulfation begins to
break down.
CAUTION:
AS THE SULFATION BREAKS DOWN, THE AMPERAGE MAY RAPIDLY RISE. CONSTANT
ATTENTION MUST BE OBSERVED TO PREVENT SERIOUS OVERHEATING OF THE BATTERY.
4.
Lower the charge rate to the lowest rate for the voltage of battery being charged.
5.
Charge the battery at this low rate until the electrolyte reaches the fully charged state as described in the tables in your
instruction manual. This may take as long as two or three days.
