CAN-bus – the POWER LED#1 remains on and DESULFATE LED#3 and CHARGE LED#4 briefly flash together at regular intervals.
POWER ON: LED #1 - Confirms AC power supply to the charger.
HIGH and LOW intensity indication: The"POWER ON" LED #1 will indicate brightly when current is delivered to the battery.
The "POWER ON" LED #1 will reduce intensity to a low level to indicate low power "ECO" mode. This will occur if there is no battery
connected, or when a battery is connected and the program finds itself in the voltage retention test mode or the 'rest' periods of
Maintenance Charge mode.
REVERSE POLARITY PROTECTION: LED #2 - Lights when the battery connections are incorrect. The charger is
so no damage will result, and the output will remain disabled until the connections are corrected.
CAN-bus :
LED #3, 4, 5, 6 and 7 flashing: A short circuit has been detected across the output terminals, or if LED #2 (REVERSE
POLARITY) is also indicating the battery connections are incorrect. The charger is electronically protected so no damage will result, and
the output will remain disabled until the connections are corrected.

STD: Battery voltage check - OptiMate 4 automatically activates if
connected battery voltage is at least 0.5 Volt.
Batteries measuring below 2 Volts at connection will proceed to
STEP 2 for 'Pulse wake up' that includes a battery short circuit test.
V
Batteries measuring 2 Volts or more will proceed directly to STEP 3.
CAN-Bus:
activate a CAN-bus controlled 12V outlet. Non activation may be due to one of the
following: Program 1 is selected / Poor connection to the 12V outlet / Battery too low to
power CAN-bus / Outdated CAN-bus programming on the vehicle - consult with the
vehicle manufacturer.
FLASHING
Pulse wake up - LED #7 (red) flashing:
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 #5/6/7 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: Severity of discharge is determined; a battery with
60% (AGM=40%) 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.
3
Output voltage increases to a maximum of 22V with current limited to 0.2A, but only if
no vehicle electronics have been detected, otherwise it moves directly to STEP 5.
IMPORTANT: Read section VERY FLAT NEGLECTED BATTERIES below.
CAN-Bus: Disabled in CAN-bus program.
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.
