USING THE OPTIMATE 2: PROCEEDING TO CHARGE
For safety reasons, the OptiMate output will only activate if a battery retaining at least 2V is connected.
VERY FLAT NEGLECTED BATTERIES:
relatively small batteries such as those used on motorcycles, lawn tractors, jet-ski's, snowmobiles and similar: 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 current charging.
Monitor the battery temperature during the first hour, then hourly there-after. Check for unusual signs, such as bubbling or leaking
electrolyte, heightened activity in one cell compared to others, or hissing sounds. If at any time the battery is uncomfortably hot to touch or
you notice any unusual signs, DISCONNECT THE CHARGER IMMEDIATELY.
ECO POWER SAVING MODE WHEN THE CHARGER IS CONNECTED TO AC SUPPLY:
switches to ECO mode when the charger is not connected to a battery resulting in a very low power draw of less than 0.5W, equivalent to
power consumption of 0.012 kWh per day. When a battery is connected to the charger power consumption depends on the current demand
of the battery and its connected vehicle / electronic circuitry. After the battery has been charged and the charger is in long term
maintenance charge mode (to keep the battery at 100% charge) the total power consumption is estimated to be 0.060 kWh or less per day.
The LED indicators referred to below, and the clauses dealing with them, are sequenced as they may come on through the course
of the program.
LED #1 Power on. Confirms AC power supply to the charger.
MODE.
LED #2 indicates inverse polarity
LED #3 CHARGE
3.1 PULSE LOW VOLT SAVE (from 2V) : Current up to 0.8A is delivered in pulses to prepare the battery to accept
normal charge. This mode is particularly effective for recovery of factory activated / "hi‑performance" pure lead
or cyclic cell AGM batteries. Charge time: Minimum 15 minutes, maximum 2 hours.
3.2 BULK CHARGE: The BULK CHARGE stage delivers a constant current of 0.8 Amps maximum into the battery, up
to a voltage of 14.2 -14.5V.
3.3 OPTIMIZE: The OPTIMIZE CHARGE mode starts when the voltage has reached 14.2 -14.5V for the first time
during BULK CHARGE stage. The control circuit now delivers pulses of current for 30 minutes to equalise the
individual cells within the battery. The battery's charge level is verified. If the battery requires further charging
the program will extend OPTIMIZE charge up to a maximum of 4 hours.
NOTE: For safety reasons there is an overall charge time limit of 96 hours.
LED #4 : MAINTENANCE -
4.1 Voltage retention test - For a battery able to remain above 12.4V throughout the 30 minute * test (NO CHARGE
CURRENT DELIVERED) LED #4 remains on. If the battery voltage falls below 12.4V the program reverts to step 3.3.
* First test period = 12 hours, or if charge delivery was less than 12 hours, test extends until 24 hours has
elapsed. Subsequent test periods are 30 minutes.
If LED#3 and #4 alternates every 3‑10 seconds, it means that after being charged the battery's voltage is not
being sustained or that despite recovery attempts the battery was irrecoverable. It may be due to a defect in the
battery itself, such as a short‑circuited cell or total sulphation, or, in the case of a battery still connected to the
