Sealey SCI90S - Manual (Page 4)

– Provides high amperage for cranking an engine with a weak or run-down battery.
5.2. Battery Type/Mode Button
5.2.1. Set the type of battery to be charged, or Desulphation Mode:
(Calcium) – Calcium batteries are acid batteries impregnated with calcium.
(Absorbed Glass Mat/Gel) – AGM batteries have electrolyte absorbed in separators consisting of a sponge-like mass of matted glass
fibre. Gel batteries contain gelled electrolytes. These batteries are sealed with valves and should not be opened.
(Desulphation Mode) – A special mode of operation designed for sulphated batteries.
NOTE: When charging a battery that is not marked, check the manual of the item which uses the battery for the correct battery type. Make sure
the charger is used for charging LEAD-ACID batteries only. It is not intended to power a low voltage electrical system. DO NOT use this
charger for charging dry-cell batteries that are commonly used with home appliances. These batteries may burst and cause injury to
persons or damage to property.
5.3. Digital Display
The Digital Display gives a digital indication of voltage, % of charge or time. The display will show the battery VOLTAGE when the
charger is not charging a battery. When it goes into charging mode, the display will automatically change to ON (to show charging has
started) and then show the percent-of-charge of the battery being charged and either 6 or 12 (the voltage the charger determined the
battery is). If you manually stop the charging process (by pressing the CHARGE RATE button) before the battery is fully charged the
display will show OFF.
• Battery % – The digital display shows an estimated charge percentage of the battery connected to the charger battery clips.
• Voltage – The digital display shows the voltage at the charger battery clips in DC volts.
NOTE: Once the charger has started charging the battery; if you press the Charge Rate button once, the output current is shut off and
the display with show OFF and then the battery voltage. If you press the Charge Rate button again, the current will go back on at the
same setting it was when it was turned off. For example: The charger is charging a battery at the slow charge rate setting. If you press
the Charge Rate button, the output is turned off. If you press the Charge Rate button again, the output will turn back on at the slow
charge rate setting.
 WARNING! This battery charger must be properly assembled in accordance with the assembly instructions before it is used, see 4.8.
6.1. Battery Information
This charger can be used with 6 and 12V batteries with rated capacities of 12 Ah to 230 Ah.
6.2. Charging
6.2.1. Ensure that all of the charger components are in place and in good working condition, for example, the plastic boots on the battery clips.
6.2.2. Connect the battery following the precautions listed in sections 1 and 4.
6.2.3. Connect the mains supply.
6.2.4. Select the appropriate settings for your battery.
IMPORTANT: This charger does not have an ON/OFF switch. ON and OFF are controlled by plugging in the charger to the mains outlet.
The charger will not supply current to the battery clips until a battery is properly connected. The clips will not spark if touched together.
6.3. Startup Defaults: When first turned on, the charger will default to the following startup settings:
• Battery Type: AGM/GEL
• Charge Rate: OFF (No charge rate selected)
After 10 minutes, if no charge rate is selected, the charger will automatically start charging at the following defaults:
• Charge Current: The lowest charge rate setting available, 3 amps.
• Charge Voltage: If no battery type is selected, 14.7V (for AGM/GEL); if CA/CA is selected, 16V; if Desulphation button is selected,
charger goes into Desulphation Mode.
6.4. Battery Connection Indicator
If the charger does not detect a properly connected battery, the CONNECTED LED will not light. Charging will not begin if the
CONNECTED LED is not on.
6.5. Automatic Charging Mode
6.5.1. When a charge rate is selected, the charger is set to perform an automatic charge. When an automatic charge is performed, the charger
switches to the maintain mode automatically after the battery is charged.
6.6. Aborted Charge
6.6.1. If charging cannot be completed normally, charging will abort. When charging aborts, the charger’s output is shut off, all of the LEDs are
turned off and the digital display will show an error code (see Error Codes). In that state, the charger
ignores all buttons. To reset after an aborted charge, unplug the charger.

SCI90S Issue: 1 - 14/05/14
6.7. Desulphation Mode
IMPORTANT: Battery must be removed from the car when using this mode, or damage to the car’s electrical system may result.
If the battery is left discharged for an extended period of time, it could become sulphated and not accept normal charge. If you select
the charger will switch to a special mode of operation designed for sulphated batteries. If successful, the charger will fully desulphate
and charge the battery, then the green LED will go on. If desulphation fails, the charger will abort and the CHARGING (yellow)
LED will flash.
6.8. Completion Of Charge
6.8.1. Charge completion is indicated by the CHARGED LED. When lit, the charger has stopped charging and switched to the Maintain
Mode of operation.
6.9. Maintain Mode
6.9.1. When the CHARGED LED is lit, the charger has started Maintain Mode. In this mode, the charger keeps the battery fully charged
by delivering a small current when necessary. The voltage is maintained at a level determined by the battery type selected.
NOTE: If the charger has to provide its maximum maintain current for a continuous 12 hour period it will go into Abort Mode. This is
usually caused by a drain on the battery or the battery could be bad. Make sure there are no loads on the battery. If there are, remove
them. If there are none, have the battery checked or replaced.
6.10. Maintaining a Battery (3A Charge Rate)
This charger has a maintenance setting that maintains both 6 and 12 volt batteries, keeping them at full charge. On this setting, it
can charge small batteries and maintain both small and large batteries. We do not recommend charging a large battery on the
maintenance setting.
NOTE: The maintain mode technology utilized in this charger allows you to safely charge and maintain a healthy battery for
extended periods of time. However problems with the battery, electrical problems in the vehicle, improper connections or other
unanticipated conditions could cause excessive current draws. As such, occasionally monitoring your battery and the charging process
is recommended.
