USING THE OPTIMATE PRO-8: PROCEEDING TO CHARGE
For safety reasons, the OptiMate output will only activate if a battery retaining at least 2V (or 1.2V for a 6V battery) is
connected, whereupon the circuit instantly diagnoses the battery condition and engages the appropriate charge mode and
lights the corresponding charge status LED.
The charger's special recovery mode cannot engage if it senses that the battery is still connected to a vehicle wiring
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 electronics will be damaged.
VERY FLAT NEGLECTED BATTERIES:
for 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 fi rst 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.
SELECTING CHARGE VOLTAGE:
IMPORTANT:
Each 6V / 12V switch controls 2 charging circuits positioned to the left and right of the switch.
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. Voltage for 6V batteries are indicated in brackets following the 12V battery voltage.

LED #1 - When not charging LED #1 indicates the colour green to confi rm AC power supply to the charger circuit.
Circuit activation and recovery of deep-discharged, neglected batteries
1.1 ACTIVATION - If the battery voltage is above 2V (1,2V), LED #1 briefl y changes colour to red to confi rm circuit activation.
For batteries with a good state of health LED #1 goes out immediately and charge LED #2 comes on.
1.2 RECOVERY - For neglected batteries in poor state of health, LED #1 remains on (red) and indicates steadily. The charge
voltage is limited at a maximum 22V (11V) while the circuit attempts to deliver a current of 200mA into the battery. If
step 1 has not concluded after 2 hours, step 2 engages automatically.
2.
Charge and charge verifi cation
2.1 CHARGE: The BULK CHARGE stage (steady LED #2) delivers a constant current of 1Amp maximum into the battery, up
to a voltage of 14,2 -14,5V (7,1 - 7,25V).
2.2 VERIFICATION: LED #2 fl ashes while the circuit verifi es battery charge level.
If the battery requires further charging the programme reverts to CHARGE for brief periods, delivering a variable current
pulse to the battery. These reversions may occur as many times as is necessary to reduce the battery's current
demand below 200mA at 13,6V (6,8V) (which is consistent with a battery that has accepted as much charge as its
basic condition allows).
When LED #2 has fl ashed continuously for 30 minutes, step 3 engages and a voltage retention test starts.
3. 4.
Voltage retention tests alternating half-hourly with battery maintenance
Flashing
LED #3 or 4 - Voltage retention test
For
a good battery LED #4 fl ashes throughout the 30 minute test. NO CHARGE CURRENT.
If
the battery voltage falls below 12,4V (6,2V) during the test LED #3 (red) willcome on and indicate steadily.
The
red LED means that after being charged the battery's voltage is not being sustained or that despite recovery attempts
the battery was irrecoverable. This 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 vehicle's wiring system, the red LED #3 may be signalling a
loss of current through deteriorated wiring or a degraded switch or contact, or in-circuit current-consuming
accessories. A sudden load such as the headlights being switched on while the charger is connected can also cause
the battery voltage to dip signifi cantly. Always remove the battery from the vehicle, reconnect the OptiMate
it to proceed through its programme once more.
Steady
on LED #3 or 4 - Automatic battery maintenance
Maintenance - fl oat charge at a safe voltage limit of 13,6V (6,8V) and up to 1A is available to counter self-discharge
Whichever LED (#4 fl ashing or #3 steady) was indicating at the end of the TEST now indicates steadily. The battery can
draw current as required to support small loads and counter self-discharge. Maintenance and voltage retention test
periods continue alternating half-hourly until the battery is disconnected. The test result is updated during each
subsequent test.
