important 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 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.
LED #1 Power on. Confirms AC power supply to the charger and 12VDC supply.
LED #2 indicates inverse polarity
LED #3 CHARGE
3.1 PULSE LOW VOLT SAVE (from 2V) : Current up to 2A 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 2 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 72 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
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. Always remove the battery from the vehicle, reconnect
the Intellicharge™ and allow it to proceed through its program once more. If a better test result is now
obtained, this suggests that the power losses are partly due to an electrical problem in the electrical system and
not in the battery itself. If the poor result persists, you are advised to take the battery to a professional service
workshop equipped with professional equipment for a more thorough investigation.
4.2 Maintenance - float charge at a safe voltage limit of 13.6V and up to 2A is available to counter self-discharge.
The battery can draw current as required to support small loads and counter self-discharge. If the battery voltage
falls below 12.4V the program reverts to step 3.3.
Maintaining a battery for extended periods:
good, for months at a time. At least once every two weeks, check that the connections between the charger and battery
are secure, and, in the case of batteries with filler caps on each cell, disconnect the battery from the charger, check the
level of the electrolyte and if necessary, top up the cells (with distilled water, NOT acid), then reconnect. When
handling batteries or in their vicinity, always take care to observe the SAFETY WARNINGS above.
Charging time:
The time required for the Intellicharge to complete a charge on a flat but otherwise undamaged
battery is roughly equal to 1/2 the battery's Ah rating, so a 10Ah battery should take no more than about 5 hours to
progress to Step 4. Deep-discharged batteries may take significantly longer.
ECO POWER SAVING MODE WHEN THE APPLIANCE 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.
