Explanation
25%
Red LED
The 25% Charge LED will slowly pulse
“on” and “off”, when the battery is less
than 25% fully charged. When the bat-
tery is 25% charged, the red Charge LED
will be solid.
50%
Red LED
The 50% Charge LED will slowly pulse
“on” and “off”, when the battery is less
than 50% fully charged. When the bat-
tery is 50% charged, the red Charge LED
will be solid.
75%
Orange LED
The 75% Charge LED will slowly pulse “on”
and “off”, when the battery is less than
75% fully charged. When the battery is
75% charged, the orange Charge LED will
be solid.
100%
Green LED
The 100% Charge LED will slowly pulse
“on” and “off”, when the battery is less
than 100% fully charged. When the bat-
tery is fully charged, the green LED will
be solid, and the 25%, 50% and 75%
Charge LEDs will turn “off”.
Mainte-
nance
Green LED
During maintenance charging, the 100%
Charge LED will pulse “on” and “off” slowly.
When the battery is topped off and fully
charged again, the 100% Charge LED will
turn solid green. The charger can be left
connected to the battery indefinitely.
UNDERSTANDING CHARGE LEDS
The charger has four Charge LEDs - 25%, 50%, 75%
and 100%. These Charge LEDs indicate the connected
battery(s) state-of-charge (SOC). See the explanation
below:
UNDERSTANDING ADVANCED DIAGNOSTICS
Advanced Diagnostics is used when displaying Error
Conditions. It will display a series of blink sequences
that help you identify the cause of the error and po-
tential solutions.
All Error Conditions are displayed with the Error
LED and Standby LED flashing back and forth. The
number of flashes between each pulse denotes a po-
tential Error Condition (except reverse polarity and
low-voltage battery).
Error
Reason/Solution
Single
Flash
Battery will not hold a charge.
Have battery checked by a
professional.
Double
Flash
Possible battery short.
Have battery checked by a
professional.
Triple
Flash
Battery voltage is too high for
the selected charge mode.
Check the battery and charge
mode.
Error LED
Solid Red
Reverse polarity. Reverse the
battery connections.
Standby
Solid Orange
Battery voltage is too low for
charge to detect or charger is in
supply. Jumpstart the battery to
raise the battery voltage.
