13. OPERATING INSTRUCTIONS
WARNING
: Failure to follow instructions may cause damage or an explosion.
Read the entire instruction manual before use.
13.1
Make sure that the charger is unplugged from the AC outlet.
13.2
Connect one of the three optional output cables to the charger output connector.
13.3
Connect the other end of the output cable to the battery.
13.4
Plug the charger into the AC outlet. The POWER ON (red) LED will glow to show that AC
power is present. Then the green and yellow LED will blink once as a self-test to make
sure that the LED is operating properly.
13.5
After three seconds, the CHARGING (yellow) LED will glow to show that charging has
begun. If none of the LEDs glow, or if the CHARGING (yellow) LED does not glow, refer
to the troubleshooting section. Charge time may vary from less than one hour to 12 hours.
13.6
When charging is complete, the CHARGED (green) LED will glow and the charger will
automatically go into maintain mode. If desired, the charger can now be unplugged from
the AC outlet.
NOTE:
If the battery has not reached at least 18-volts after five minutes of charging or at
least 24-volts after four hours of charging, the charger will abort the charging process and
turn the yellow LED off.
14. CALCULATING CHARGE TIME
To determine the time needed to fully charge your battery, you must first determine the
battery’s charge level with a hydrometer or electronic Percent-of-Charge Tester. The
following table will help you convert hydrometer readings to percent of charge values.
Specific Gravity
Percent of Charge
Percent of Charge Needed
1.265

0%
1.225
75%
25%
1.155

1.120

When the percent of charge and the Amp Hour (AH) rating of your battery is known, you
can calculate the approximate time needed to bring your battery to a full charge.
