Maintain Mode
11.7
When the CHARGED (green) LED is lit, the charger has started Maintain
Mode. In this mode, the charger keeps the battery fully charged by deliver-
ing a small current when necessary. If the battery voltage drops below a
preset level, the charger will go back into Charge Mode until the battery
voltage returns to the full charge level, at which point the charger will
return to Maintain Mode. The voltage is maintained at a level determined
by the BATTERY TYPE selected.
Using the Battery Voltage Tester
11.8
Overview
This battery charger has a built-in voltmeter to test your battery’s state
of charge. The charger does not have a built in load tester. As such, a
recently charged battery could have a temporarily high voltage due to
what is known as “surface charge”. The voltage of such a battery will
gradually drop during the period immediately after the charging system is
disengaged. Consequently, the tester could display inconsistent values for
such a battery. For a more accurate reading, the surface charge should be
removed by temporarily creating a load on the battery, such as by turning
on lights or other accessories for a couple of minutes before you read the
display. Read it a couple of minutes after you have shut the headlights off.
Testing Sequence
: There are four basic steps required to test the battery
state of charge:
With the charger unplugged from the AC outlet, connect the charger to
1.
the battery following the instructions given in Sections 6 and 7.
Plug the charger AC power cord into the AC outlet, following the in-
2.
structions given in Section 8.
If necessary, press the BATTERY TYPE button until the correct type is
3.
indicated.
Read the voltage on the digital display or press the Display Mode but-
4.
ton to set the tester to BATTERY % to read the voltage as a percent-
age of charge.
Tester and Charger
: When first turned on, the unit operates only as a tes
-
ter, not as a charger. To continue to use it only as a tester, avoid pressing
the CHARGE RATE button. Selecting a charge rate activates the battery
charger and deactivates the tester.
Power-Up Idle Time Limit
: If no button is pressed within 15 minutes
after the battery charger is first powered up, the charger will automatically
switch from tester to charger if a battery is connected. In that case, the
charger will be set to the start up default settings.
Tester without Time Limit:
If either the DISPLAY MODE or BATTERY
TYPE button is pressed within the first 10 minutes after the battery
charger is powered up, the unit will remain a tester (not a charger)
indefinitely, unless a charge rate is selected.
