NOTES ON TEST RESULTS: The voltage of a cooled battery is directly proportional to its State Of Charge
percentage (SOC%). Immediately following charging a battery may briefly hold a higher voltage, as charging
raises the temperature of chemical elements within the battery. A battery recovered from a deep discharged
state may need longer to cool and voltage to settle to reflect its true state of charge (SOC%).
TROUBLESHOOTING GUIDE:
OPTIMATE 4
1) Battery in vehicle, CAN-bus program 2 or 4
WON'T CHARGE
selected > Battery voltage may be too low to
power vehicle's CAN-bus system.
a) Program 2 (Pb) : Minimum 5V required.
Disconnect battery from vehicle, select program
1 and charge directly to battery.
b) Program 4 (LFP) : Minimum 8.8V min.
required. Disconnect battery from vehicle, select
program 3 and charge directly to battery.
2) Poor connection to the 12V outlet - check
connector / try charge direct to battery.
3) Outdated CAN-bus programming on the vehicle
- consult with the vehicle manufacturer.
ERROR!
1) LFP battery in vehicle, Program 3 or 4 :
abnormal charging or battery damage has been
LED 8 flashing /
detected. Disconnect battery from vehicle circuity,
blinking.
select program 3 and charge direct to battery.
TEST RESULT
1) Battery in vehicle -
a) Program 1 & 2 (Pb): STD 'flooded' battery:
LED 5 & 6
Good > 80%-100%
b) AGM / LFP battery: 60-80%. Vehicle
electronics may be drawing power and
discharging the battery. Disconnect from vehicle
circuitry and charge again.
MAINTENANCE CHARGE: LED #6 / 7 / 8 steady on according to state of charge
measured during STEP 8.
Float voltage setting: 13.6V. The general maintenance program consists of 30
minute float charge periods, followed by and alternating with 30 minute 'rest'
periods, during which there is no charge delivered. Additional adjustments are
made for different battery chemistries.
Programs 1 & 2 (Pb battery) : The "50% duty cycle" maintenance program for
lead-acid batteries prevents loss of electrolyte in sealed batteries and minimizes
gradual loss of water from the electrolyte in batteries with filler caps, and thereby
contributes significantly to optimizing the service life of irregularly or seasonally
used batteries. During "float charge" a continuous LOW CURRENT PULSE IS
DELIVERED TO PREVENT SULFATION, further extending battery power and life.
LED indication: For batteries with a good state of health LED #6 (green) will
remain on. Exception: STD wet cell batteries with filler caps have a lower fully
charged voltage: LED #6 remains on together with LED #7.
Programs 3 & 4 (LFP battery) : The OptiMate Lithium maintenance program is
fully automatic, it continuously monitors the battery voltage and delivers current
only if it sensed the battery has lost charge (possibly through connected vehicle
or other circuitry or self discharge). This Lithium specific maintenance program
guarantees the battery will remain at or close to full charge, but never
overcharged.
LED indication: For batteries with a good state of health LED #6 (green) will
remain on.
4) Battery in vehicle, program 1 or 3
selected - Battery voltage is below 0.5V.
a) Program 1 or 3 : Disconnect battery from
vehicle, wait 5-10 minutes for battery to
recover voltage and try again.
b) Program 3 (LFP): Battery with resetable
BMS - disconnect battery from vehicle and
then use BMS reset procedure.
If OptiMate 4 still does not charge, then have
the battery professionally assessed, or
replace battery.
2) Program 3 for Li-Ion / LFP, battery NOT
connected to vehicle circuitry. Battery has
permanent damage. Do not charge again.
Replace the battery.
2) Battery NOT connected to vehicle circuitry -
a) Program 1 & 2 (Pb): STD 'flooded'
battery: State of Health (S.O.H.) is good >
80%-100%.
b) AGM / LFP battery : 60-80%. Battery has
lost power and may need to be replaced
soon.
