Charging Tips; Maintenance And Care - Schumacher SC-7500A SpeedCharge Owner's Manual

Read this entire manual before using your charger. The tips below serve only as a guide
for specific situations.
If your vehicle won't start: You don't need
to fully charge a battery to start your ve-
hicle. If the charger won't start your vehicle
using the 75A START rate, try charging the
battery using the 12A   30A rate for 10
or 15 minutes. That should charge the bat-
tery enough to allow the 75A START rate
to start the vehicle. If the vehicle will then
be operated continuously for an extended
period (such as a long drive), the vehicle
could charge the battery back to normal
during that period. If the vehicle will only
be operated for a short period (short drive),
the battery might need to be charged again
before it could start the vehicle again.
A minimal amount of care can keep your battery charger working properly for years.
1. 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.
2. Coil the input and output cords neatly when storing the charger. This will help pre-
vent accidental damage to the cords and charger.
3. Occasional cleaning of the case of the charger with a soft cloth will keep the finish
shiny.

CHARGING TIPS

MAINTENANCE AND CARE

Reviving your battery: If you only wish
to charge your battery enough to operate
your vehicle, you don't need to wait for the
entire charging process to be completed.
When the charger displays a battery %
of 77 or more (see page 13), the battery
has usually been charged enough for the
vehicle to start and operate normally.
Completing an interrupted charge: If
the charging process has been interrupted
and restarted after the charger displays a
battery % of 85 or more, the charger could
go straight to Maintain Mode (see page 8).
However, if the original charge was started
using 12A   30A, the charge can often
be completed using the 2A rate.
