Push and release the SELECT pushbutton. The mode selection changes
when the button is released.
SAVE (#3), CHARGE (#4) and/or TEST (#6,7,8) LEDs flash twice to
confirm the new selection is in memory. Selection remains even if AC
power is lost.
CHARGE MODES: LED #1a = 14.4V. LED #1b = 14.7V.
A charge mode automatically activates and will proceed to STEP 3 if
13.6V
connected battery voltage is at least 0.5 Volt.

14.7V selection - This higher charge voltage is only suitable for certain

premium AGM or sealed deep cycle / traction 12V lead-acid batteries.
Other 12V lead-acid batteries will be overcharged and may suffer
4
permanent damage. Confirm battery charge voltage requirement before
making the 14.7V selection. If you are not sure, select 14.4V. It is safe

for any 12V lead-acid battery.
PS (Power Supply): LED #2.
With 14.4V or 14.7V charge program in operation, press the button (3
13.6V
sec.) until LED #2 lights. A fixed 13.6V is delivered, with up to 8 Amps of
12V
current available.

LED indication during Power Supply mode:

LED #6, #7, #8 = voltage at 13.6V, current draw below 8 Amps.
LED #7 & #8 = voltage below 13.6V, current draw exceeds 8 Amps.

LED #8 = voltage below 12.2V, battery SOC < 25%.
To turn off PS mode and return to charging, press the button (3 sec.)
8
until LED #2 turns off and the previously selected CHARGE mode (14.4V /
14.7V) re-activates.
12.2V
WARNING: PS mode (13.6V) remains active even if disconnected
from battery. Do not touch clips together.
REVERSE POLARITY / incorrect battery connection: The charger is
electronically protected so no damage will result, and the output will
remain disabled until the connections are corrected.
Following correction charge modes 14.4V & 14.7V automatically activate
and will proceed to STEP 3. PS mode - see below.
PS (power supply) LED #2 flashing ON/OFF: Indicates that a fault

condition such as reverse connected battery, a short circuit or overload

was detected, or AC power was interupted during PS mode.
If necessary correct the fault condition, then push and release the
SELECT pushbutton. Output is restored when LED #2 (PS) turns full on.

The battery SAVE mode engages if the battery is less than 50% charged OR
voltage is between 0.5 to 12.4 Volt. Charge time: 15min to 2hrs.

TURBO SAVE : The battery was diagnosed as sulphated, unable to accept
or hold charge - Current is limited to 0.4A and voltage is allowed to rise
towards 16V to check for active vehicle electronics, if detected, STEP 5
STEP 4 immediately engages. Otherwise voltage may briefly rise as high as 22V to
overcome sulphation within the battery.
IMPORTANT: Read section VERY FLAT NEGLECTED BATTERIES below.
With voltage limited to 14.4V / 14.7V (as selected) current is delivered in
STEP 5
pulses to prepare the battery to accept normal charge and increase its state
of charge towards 50%.
