Maintenance And Care - Schumacher SE8 Owner's Manual

CHARGING A BATTERY OUTSIDE OF
THE VEHICLE
1. Place battery in a well-ventilated area.
2. Clean the battery terminals.
3. Connect a 24-inch long, 6-gauge (AWG)
insulated battery cable to the NEGATIVE
(NEG, N, -) battery post (i.e., jumper
cable) (not provided).
4. Connect the POSITIVE (RED) clamp to
the POSITIVE (POS, P, +) battery post.
5. Position yourself and the "negative post
extension" cable as far away from the
battery as possible, and connect the
NEGATIVE (BLACK) clamp to the cable's
free end.
6. Connect the charger to the electrical outlet.
7. When charging is complete, disconnect
the charger from the AC power,
disconnect the negative clamp, and finally
the positive clamp.
8. A marine (boat) battery must be removed
and charged on shore.
NOTE: This charger is equipped with an
auto-start feature. Current will not be
supplied to the battery clamps until a battery
is properly connected. The clamps will not
spark if touched together.
AUTOMATIC CHARGING MODE
When an Automatic Charge is performed,
the charger switches to the maintain mode
automatically after the battery is charged.
ABORTED CHARGE
If charging cannot be completed normally,
charging will abort. When charging aborts,
the charger's output is shut off and the
CHARGING
reset after an aborted charge, unplug the
charger from the AC outlet, wait a few
moments and plug it back in.
A minimal amount of care can keep your
battery charger working properly for years.
• Clean the clamps each time you are
finished charging. Wipe off any battery fluid
that may have come in contact with the
clamps to prevent corrosion.
• Occasionally cleaning the case of the
charger with a soft cloth will keep the finish
shiny and help prevent corrosion.

DESULFATION MODE
Desulfation could take 8 to 10 hours. If
desulfation fails, charging will abort and the

COMPLETION OF CHARGE
Charge completion is indicated by the
CHARGED
pulsing, the charger has switched to the
maintain mode of operation.
MAINTAIN MODE (FLOAT-MODE
MONITORING)
When the CHARGED
pulsing, the charger has started maintain
mode. In this mode, the charger keeps the
battery fully charged by delivering a small
current when necessary. If the charger has
to provide its maximum maintain current for
a continuous 12 hour period, it will go into
abort mode (see Aborted Charge section).
This is usually caused by a drain on the
battery or the battery could be bad. Make
sure there are no loads on the battery. If
there are, remove them. If there are none,
have the battery checked or replaced.
MAINTAINING A BATTERY
The SE8 charges and maintains both 6 and
12 volt batteries, keeping them at full charge.
NOTE: The maintain mode technology
utilized in Schumacher maintainers allows
you to safely charge and maintain a healthy
battery for extended periods of time.
However, problems with the battery, electrical
problems in the vehicle, improper
connections or other unanticipated conditions
could cause excessive current draws. As
such, occasionally monitoring your battery
and the charging process is required.
• Coil the input and output cords neatly when
storing the charger. This will help prevent
accidental damage to the cords and charger.
• Store the charger unplugged from the AC
power outlet in an upright position.
• Store inside, in a cool, dry place. Do not
store the clamps clipped together, on or
around metal, or clipped to the cables.
