Schumacher SC-7500A Battery Charger User Manual

Read this entire manual before using your charger. The tips below serve only as a guide
for specic situations.
If your vehicle won’t start: You don’t
need to fully charge a battery to start your
vehicle. If the charger won’t start your
vehicle using the ENGINE START rate, try
charging the battery using the REGULAR
BATTERY rate for 10 or 15 minutes. That
should charge the battery enough to al-
low the ENGINE 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.
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 12), 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 7).
However, if the original charge was started
using the REGULAR BATTERY setting,
the charge can often be completed using
the SMALL BATTERY setting.
