Operating Instructions - Napa 90-150 Owner's Manual

– The electrolyte in a GEL cell has a
silica additive that causes it to set up or
stiffen. The recharge voltages on this type
of cell are lower than those for other styles
of lead-acid battery. This is probably the
most sensitive cell in terms of adverse
reactions to overvoltage charging. Gel

11. OPERATING INSTRUCTIONS

CHARGING THE BATTERY
Keep in mind: when charging a battery,
the more a battery is discharged, the
faster it absorbs charge from the charger.
In other words, it takes longer for the
battery to absorb the last few percents of
charge than the first several percents.
WARNING: When the START button is
pressed in either Boost mode, Charge/
Maintain mode or Engine Start mode, the
clamps are energized and will spark if
touched together. A spark near the battery
may cause an explosion.
NOTE: A marine (boat) battery must be
removed and charged on shore.
1. Place battery in a well-ventilated area.
2. Clean the battery terminals.
3. Connect the battery, following the
precautions listed in sections 6 and 7.
4. Connect the charger to the electrical
outlet.
5. With the charger plugged in and
connected to the battery of the
vehicle, select the Charge/Maintain
rate and the battery type.
• If the voltage of the battery is under
12.7V, the unit will automatically
switch to Boost mode when the Start
button is pressed. When the unit
automatically switches to Boost mode,
the 40A Boost LED will light.
When the automatic Boost mode is
completed, the unit will automatically
switch to the Charge/Maintain rate
and complete the charge.
• If the unit doesn't automatically
switch to Boost Mode when the Start
button is pressed, you can manually
put the unit into the Boost mode.
Press the

will start. Boost mode will remain
energized until the Rate Selection
button is pressed. The unit will not

cycle application and may last a bit longer
in hot weather applications. If the wrong
battery charger is used on a gel cell
battery, poor performance and premature
failure will result.
automatically switch to the Charge/
Maintain rate to complete the charge.
6. Press the START button.
• If the unit automatically switches to
the Boost, but the 6<>2A Charge/
Maintain rate is preferred, press the
Rate Selection button (while still
boosting) until the
LED is illuminated.
7. To stop the charging process, press
the STOP button and disconnect the
charger from the AC outlet and battery,
as explained in sections 6 and 7.
BATTERY CHARGING TIMES
APPLICATION

AUTOMOTIVE
MARINE
Times are based on a 50% discharged
battery and may change, depending on age
and condition of battery.
ABORTED CHARGE
If charging cannot be completed normally,
charging will abort. When charging
aborts, the charger's output is shut off,
and the display will show FNN where nn
is an error code (see Troubleshooting for
a description of the error codes). Do not
continue attempting to charge this battery.
Have it checked or replaced.
DESULFATION MODE
Desulfation could take 8 to 10 hours. If
desulfation fails, the display will show
F02, charging will abort and the
Battery (red) LED will light.
COMPLETION OF CHARGE
Charge completion is indicated by the
Charged/Maintaining (green) LED.
When lit, the charger has switched to the
maintain mode of operation.
