VERY FLAT NEGLECTED BATTERIES: If the battery is deeply discharged (and possibly sulfated),
remove from the vehicle or equipment and inspect the battery before connecting the charger for a
recovery attempt.
The charger's recovery mode may not engage if it senses that the battery is still connected to a
circuit which effectively offers a lower electrical resistance than the battery on its own. However, if the
deep-discharged battery is not removed for recovery, neither battery nor vehicle or equipment electronics
will be damaged.
Pay particularly close attention to the following A battery left deep-discharged for an extended period
may develop permanent damage in one or more cells. Such batteries may heat up excessively during high
The OPTIMIZE mode starts when the voltage has reached 7.2V / 14.4V
The ampmatic™ current control program now delivers pulses of
current to equalise the individual cells within the battery and optimizes
charge level.
Ca/Ca
OPTIMIZE mode charging time: minimum 10 minutes up to a maximum of
2 hours. NOTE: Charge time is usually extended if there is higher than
expected current draw by connected circuitry or battery health is less than
optimal.
For safety reasons there is an overall charge time limit of 72 hours for
STEP 4, 5 and 6.
TEST after charge : Delivery of current to the battery is interrupted for
30 minutes* to allow the program to determine the battery's ability
* IF charging started in SAVE mode (LED #3) the voltage retention test is

extended to 12 hours to confirm battery health.
LED #5 (green) will remain on for batteries able to hold 50% or higher
state of charge (SOC%), otherwise the TEST result is adjusted lower (LED
#6) 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%).
LED #6 flashing / blinking - The battery voltage has reduced below 6.1V /
12.2V (50% SOC for a STD wet cell battery, 25% SOC for an AGM battery).
The OptiMate will try recharge the battery again and then repeat the test.
Also read section "NOTES ON TEST RESULTS" below.
MAINTENANCE CHARGE: Float voltage setting: For 6V batteries: 6.8V.
For 12V batteries: 13.6V.
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.

The 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 SULPHATION, further extending battery power and life.
If the OptiMate senses the battery has suddenly lost charge the
program will revert back to STEP 5 (CHARGE).
