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.
The CHARGE mode engages if the battery state of charge was
50% or higher or once the battery has been sufficiently recovered
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.
Maximum charge current: 12V battery => 6A 24V battery => 3A.
Engages when the voltage has reached 14.4V / 28.8V
(AGM: 14.7V/29.4V) for the first time during STEP 5.
The ampmatic™ current control program now delivers pulses of
current to equalise the individual cells within the battery and optimizes
charge level.
Charge time during this step varies between 10 and 120 minutes,
influenced by initial battery State Of Charge and health as measured in
STEP 3, and current draw by connected circuitry.
For safety reasons there is an overall charge time limit of 72 hours
for STEP 4, 5 and 6.
Delivery of current to the battery is interrupted for 30 minutes**
to allow the program to determine the battery's ability to retain
charge.

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

Float voltage setting: For 12V batteries: 13.6V nominal at 20°C (68°F),

For 24V batteries: 27.2V nominal at 20°C (68°F). The float voltage is
inversely regulated according to ambient temperature; i.e., voltage is
increased at lower temperature, decreased at higher temperature.
Adjustment: -0.004V / cell / °C above or below 20°C (68°F).
Continuous float maintenance charge will be applied to the battery if
the charger sensed that connected circuitry has a current draw
exceeding 200mA, otherwise the charger proceeds with the standard
maintenance mode. Standard maintenance mode consists of 30
minute float charge periods followed by and alternating with 30 minute
'rest' periods, during which there is no charge delivered. This "50%
duty cycle" 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.
If the OptiMate senses the battery has lost charge the program will
during STEP 4.
MAINTENANCE CHARGE: LED #6 / 7 / 8 steady on
