STEP 2 for 'Pulse wake up' that includes a battery short circuit test.
Batteries measuring 2 Volts or more will proceed directly to STEP 3.
FLASHING
Pulse wake up - LED #8 (red) flashing:
test signal to see if the battery is recoverable.
Once the voltage holds above 2 Volts and no short circuit has been detected the
program will commence to STEP 3.
If flashing continues the following conditions may prevent the charge program from
progressing:
1) Vehicle circuitry remains connected to the battery.

NOTE: If the battery under charge is in a low voltage or suphated state,

for the most effective charge and test results disconnect the battery
from the vehicle circuitry and then charge.
2) Battery has multiple short circuited cells. The battery has permanent damage and
should be replaced.
TEST LEDs #6/7/8 indicate the battery condition prior to charging. Consult the table
below to match TEST LED indication to an estimated state of charge percentage
(SOC%). Charging commences after 10 seconds.

Decisions made during the test:
Charge voltage during STEP 6 and 7 is adjusted according to the measured ambient
temperature.
STEP 7 OPTIMIZE minimum charge time is set according to the test result, varying
between 10 minutes for a battery with 80% or higher state of charge to 120 minutes for
a battery with 40% or less state of charge.
Severity of discharge is determined; a battery with 60% or more charge progresses
directly to STEP 6 where-as a severely discharged battery progresses to STEP 4 and 5.
Severely discharged batteries will undergo a longer test (up to 12 hours) during STEP 8.
Charge time: maximum 2 hours.
Output voltage increases to a maximum of 22V with current limited to 0.4A, but only if
no vehicle electronics have been detected, otherwise it moves directly to STEP 5.
IMPORTANT: Read section VERY FLAT NEGLECTED BATTERIES below.
battery has sufficiently recovered during ADVANCED SAVE.
CHARGE TIME : min 15 minutes, max. 2 hours.
Current is delivered in pulses to prepare the battery to accept normal charge.
This step is particularly effective for recovery of factory activated / "hi-performance"
pure lead or cyclic cell AGM batteries.
Engages if the battery state of charge was 50% or higher (as tested in
STEP 3) or once the battery has been sufficiently recovered during STEP 5.
The ampmatic™ charge current monitoring and control program automatically
determines the most efficient rate of charge current for the connected battery,
according to its state of charge, state of health, and electrical storage capacity.
