reverse battery polarity, defective harness, blown harness fuse, severely discharged battery, or
other problem and resolve before proceeding.
6)
Turn on BatteryMINDer by moving the power switch to the CHARGER position. Verify
Power-
Status
indicator lights
GREEN
within 30 seconds or less. The charger will begin by checking the
battery voltage and ability to charge. If indicator lights
RED
, disconnect BatteryMINDer from
aircraft battery. Check for short circuit or reverse battery polarity. Resolve problem before
continuing.
7)
If the battery does not have at least a normal fully discharged voltage (21 volts minimum) the unit
will begin charging in the “Soft-Start” mode to determine if the battery can be safely charged. If it
cannot, the
Power-Status
indicator will
FLASH RED
and charging will be stopped. Battery
should be carefully checked under a load by a qualified aviation technician before attempting to
charge it again.
Note: If the battery does not have a minimum no load 6 volts, the Power-Status
will light RED and charger will reject battery for charging.
No further effort should be made to charge this battery with this charger or any charger.
Discard this battery, unless it has just been subjected to a long period of continuous
discharge under a load such as can occur with leaving lights on or cranking an engine
excessively. Remove battery from aircraft for servicing per manufacturer’s
maintenance manual. Allow such a battery to “Rest” for several hours (overnight if
possible) before determining if it is defective. Be very suspicious of any 24-volt battery
that does not have at least 22 volts before it is recharged. It may well be seriously
damaged and unsafe for any type of use or recharge. The unit’s
Battery Condition
indicator will show whether battery is less than 22-Volts (
YELLOW
) or greater than
22-Volts (
GREEN
)
8)
Verify
Charge-Float
indicator lights
GREEN
. If indicator is not illuminated, charger is not
engaged. If charger is
FLASHING GREEN
, then battery is already fully charged and charger
has automatically entered its maintenance or float mode. Battery will be maintained at its
optimum state of charge. Full-time conditioning and long-term desulfation will occur in this
mode.
9)
After battery has been fully charged, the
GREEN
Charge-Float
indicator will begin blinking. It
will continue to blink indefinitely, unless unit is disconnected from battery or Stop/Restart button
is pressed. If the battery cannot be fully charged, the
Charge-Float
indicator will not flash and
the
RED
Power-Status
indicator will flash. Battery may not be able to be fully charged, may be
too large or too deeply discharged to be fully charged in the normal time allowed by charger. If
you are certain battery is not defective, having read and understood completely all of the above
concerns and conditions, proceed to restart the charging sequence by pressing and holding the
Reset button for approximately 5 seconds until all indicators flash.
10)
If battery is not defective, it should fully charge after being restarted. After sufficient time has
lapsed the
Charge-Float
indicator will
FLASH
GREEN
confirming battery is now fully
charged.
Special Note for Aircraft with Dual Battery Systems:
If attempting to charge more than one battery at a time, it is very likely the charger will
need to be restarted as described in order to completely charge multiple batteries. We
do not recommend charging more than one battery at a time without confirming the
individual condition of each battery and monitoring the charging and batteries closely.
A better solution is to charge each battery separately and then connect them together
for long term maintenance-float charging. See section on Maintaining Multiple
Batteries.
