This final charge mode starts when the voltage has reached 28.8V for
the first time during STEP 7.
The
ampmatic
™ current control program now delivers pulses of
current to equalise the individual cells within the battery and
optimizes charge level.
Minimum charge time is influenced by initial State Of Charge as
measured during STEP 3, varying between 10 minutes for a battery
with 80% or higher state of charge to the maximum of 120 minutes
for a battery with 40% or less.

TEST after charge : Delivery of current to the battery is
interrupted for 30 minutes** to allow the program to determine
the battery’s ability to retain charge.
**
IF charging started in SAVE mode (LED #3) the voltage retention
test is extended to 12 hours to confirm battery health.
LED #6 (green) will remain on for batteries able to hold 90% or
higher state of charge (SOC%),
otherwise the TEST result is
adjusted lower (LED #7, LED #8) in real time according to the
measured battery voltage. Consult the table on page 2 to match TEST
LED indication to an estimated state of charge percentage (SOC%).

MAINTENANCE CHARGE: LED #6 / 7 / 8 steady on
according to final voltage measured at termination of STEP 9.
The
MAINTENANCE CHARGE CYCLE
consists of 30 minute charge
periods followed by and alternating with a 30 minute ‘rest’ periods,
during which there is no charge current.
During the 30 minute charge cycles current is delivered only if the
battery has lost charge.
The
BATTERY REFRESH CYCLE
is performed if the charger detects
the battery has suddenly lost significant charge. The program reverts
to STEP 8 (LED #5) before returning to STEP 9 and STEP 10 .

TUNE battery support mode, for engine tuning or diagnosis
:
A fixed 27.2V is delivered, with up to 4 Amps of current available to
prevent or slow down battery disharge.
TO ACTIVATE:
With OptiMate Lithium connected and charge mode in
STEP 8 or higher, press button for 3 seconds until LED #1b and LED
#6, #7 and #8 light together.
LED indication during TUNE mode:
LED #6, #7, #8
= power draw is normal.
LED #7 & #8
= Power draw is exceeding what OptiMate Lithium can
deliver on its own, the battery also delivering power and discharging.
LED #8 = WARNING! Battery is down to 10% SOC
, with an
estimated 1-2 minutes support remaining.
If battery loses further
charge
TUNE mode will automatically de-activate and CHARGE STEP
4 (LED #3) will re-activate.
TO DE-ACTIVATE
MANUALLY
and return to CHARGE program : Place
and hold finger on Select button. After 3 seconds standard charging
& 24-7 maintenance will resume.
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
