can be seen from the outside, examine the battery carefully to try to determine if any cells seem different to the others

(for example, with white matter between the plates, plates touching). If mechanical defects are apparent do not

attempt to charge the battery, have the battery professionally assessed.

instructions carefully. If applicable, carefully and exactly follow acid filling instructions.

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.

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.

 CHARGE: The BULK CHARGE stage ( LED #3) delivers a constant current of about 0,8 Amps maximum into the

battery, up to a voltage of 14,2 -14,5V.

 VERIFICATION: LED #4 turns on while the circuit verifies battery charge level.

If the battery requires further charging the programme reverts to BULK CHARGE (LED #3) 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 (which is consistent with a battery that has accepted

as much charge as its basic condition allows). (see expected Charging time below.

If LED#3 and #4 alternates every 2-3 seconds the battery may be in a sulphated condition and unable to initially

accept charge current. Monitor for 2 hours whilst the charger attempts to deliver charge to the battery. A lightly

sulphated battery may recover and accept full charge current as confirmed by a steady LED#3. If the condition

remains unchanged the battery may be in an advanced state of sulphation and 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, it 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 significantly. Always remove the battery from the vehicle, reconnect the OptiMate

™

and

allow it to proceed through its programme once more.
