WARNING – RISK OF EXPLOSIVE GASES.
WORKING IN VICINITY OF A LEAD-ACID BATTERY IS DANGEROUS.
BATTERIES GENERATE EXPLOSIVE GASES DURING NORMAL
BATTERY OPERATION. FOR THIS REASON, IT IS OF UTMOST
IMPORTANCE THAT YOU FOLLOW THE INSTRUCTIONS EACH TIME
YOU USE THE CHARGER.
TO REDUCE RISK OF BATTERY EXPLOSION, FOLLOW THESE
INSTRUCTIONS AND THOSE PUBLISHED BY BATTERY MANUFAC-
TURER AND MANUFACTURER OF ANY EQUIPMENT YOU INTEND TO
USE IN VICINITY OF BATTERY. REVIEW CAUTIONARY MARKING ON
THESE PRODUCTS AND ON ENGINE.
IMPORTANT: READ AND SAVE THIS SAFETY AND INSTRUCTION MANUAL.

NOTES FOR TESTING BATTERY %14.8
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
on lights or other accessories.
The battery % ranges from 0 to 100.
The battery tester is only designed to test batteries. Testing a device with
a rapidly changing voltage could yield unexpected or inaccurate results.
USING THE BUILT-IN ALTERNATOR TESTER15.
This battery charger has a built-in alternator tester that displays either
an accurate alternator voltage or an estimate of the alternator’s relative
output compared to normal alternators. The Alternator % values displayed

tor tester functions the same as the battery tester (see previous section of
this manual for details) with a few differences.
TESTING SEQUENCE15.1
There are three basic steps required to use the SC-8020A as an alternator
tester.
1. Connect the battery clamps (see sections 6 and 7).
2. Connect the charger power cord to a 120V AC wall outlet (see section 8).
3. Start the vehicle and turn on the vehicle’s headlights. Read the voltage
on the digital display or press the DIGITAL DISPLAY button to set the
tester to ALTERNATOR % and read the alternator percent.

The alternator percent display can range from 0 to 199.
The DIGITAL DISPLAY cannot be set to ALTERNATOR % during charg-
ing.
