COMPLETION OF CHARGING: Charge
completion is indicated by the
CHARGED (green) LED; when lit, the
charger has stopped charging and
switched to the Maintain Mode of
operation.
MAINTAIN MODE: When the
CHARGED (green) LED is lit, the
charger has started Maintain Mode. This
mode of operation is also known as
Float-Mode Monitoring. In this mode,
the charger keeps the battery fully
charged by delivering a small current,
when necessary. The voltage is main-
tained at a level determined by the
BATTERY TYPE selected.
GENERAL CHARGING NOTES:
The unit is designed to control its
cooling fan for efficient operation.
Consequently, it is normal for the fan to
start and stop when maintaining a fully
charged battery. The fan does not run in
Tester Mode.
If the charge mode is changed after
charging has started (by pressing the
CHARGE RATE or BATTERY TYPE
button), the charging process will be
restarted.
The voltage displayed during charging is
the charging voltage and usually will be
higher than the battery’s resting voltage.
Read this entire manual before using your charger. The tips below serve only as a
guide for specific situations.
CHARGING TIPS
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 70A START rate,
try charging the battery using the 20A
rate for 10 or 15 minutes. That should
charge the battery enough to allow the
70A 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 14), 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 inter-
rupted and restarted after the charger
displays a battery % of 85 or more, the
charger could go straight to Maintain
Mode (see top of this page). However, if
the original charge was started using
20A, the charge can often be completed
using the 2A rate.
