OPERATING INSTRUCTIONS

Charging Process
Fully automatic 7 stage charging system:

  • Analysis / Desulphation (Charging stage 1 illuminated) – A small voltage pulse is applied to the battery to ensure it can effectively and safely accept a charge. Desulphation uses pulse reconditioning to gently remove any sulphation build up on the battery plates and prevents oxidization. Stabilises electrolyte consistency and minimises the battery temperature rising by charging, recovers battery capacity and can help extend battery life.
  • Soft Start (Charging stage 2 illuminated) – The soft start function improves the batteries charging capability, reduces gas and heat build-up and can improve electrolyte consistency which can become uneven in the battery cells from day to day use. A steadily increasing current is applied over a set time so as not to initially overload the battery. This stage prepares the battery for the more intense charging stages to follow.
  • Bulk Charge (Charging stage 3 illuminated) – Maximum charge current is delivered to the battery to minimise charge times.
  • Absorption (Charging stage 4 illuminated) – Reduces the current supplied to the battery and ensures that the battery has been completely charged without the risk of being overcharged.
  • Analysis (Charging stage 5 illuminated) – The charger shuts off power and measures voltage drop over a set time. If unacceptable readings are measured, this may indicate an internal short or other issue inside the battery. If the battery has a fault the charger will illuminate the Battery Error LED indicator (Red LED). The charger will cut output and not continue to charge until it is either switched off, or the battery is removed.
  • Boost / Equalisation charge (Charging stage 6 illuminated) – Once the battery is fully charged, the charger will equalise all the battery cells by providing a steady set voltage over a programmed period, at low current.
  • Float Stage (Charging stage 7 illuminated) – Once the battery is fully charged, the charger will provide a constant voltage of 6.85V/13.7V/27.4V to maintain the battery at a full level without damaging the battery.

Temperature Compensation – This charger has a temperature compensation feature that will reduce the output current of the charger if the charger internal temperature exceeds its set limit. This protection feature will prevent the battery and charger from damage if the bulk stage takes an extended time – particularly if a larger than recommended battery has been connected. There is no indicator to show temperature compensation.
The 6V / 12V / 24V, 8A/12A/16A fully automatic 7 stage battery charger is designed to effectively charge most automotive battery types including lead acid, calcium, maintenance free, Gel and AGM and 12V Lithium batteries. They are manufactured to the latest design parameters and highest quality levels. There are no buttons to decipher – the specially designed microprocessor charging system automatically selects the correct voltage and current setting and output levels for the size and type of the battery, greatly assisting prolonged battery life and user safety. Please adhere to all safety directions in this manual and retain for later use.

Important Safety Instructions:

  • Battery chargers contain hazardous voltages. There are no user serviceable components inside the charger. Do not disassemble this product.
  • If the AC supply cord is broken or damaged, it must be replaced a qualified person only.
  • This battery charger is for use with 6, 12 and 24V electrical systems only. Care should still be taken to correctly identify the correct voltage on vehicles and light trucks BEFORE the battery charger is connected and switched on.

BATTERY CHARGER OPERATION

This charger has been designed to be as simple to use as possible. As a result, there is only one input button for Lithium charging mode. The charger has an advanced on board micro-processor that will take care of every setting required.

To commence battery charging:

  • Unwind both 230V and 12V power leads from the rear of the charger.
  • Connect the Red POSITIVE (+) clamp to the battery Red POSITIVE (+) terminal
  • Connect the Black NEGATIVE (-) clamp to the Black NEGATIVE (-) terminal
  • Plug in the 230v mains power cord, and switch on power.
  • The charger will take approximately 1 minute to complete its voltage diagnostics to detect the correct battery voltage, once complete the correct LED will illuminate for 6, 12 or 24V operation.
  • Charging will now commence automatically.
  • 12V LITHIUM BATTERY ONLY – Press and hold MODE button for 3 seconds until LITHIUM LED indicator lights up. 12V Lithium Mode charging will remain activated when the unit is switched off and then switched back on due to its memory retaining function.
  • View the status LED indicators on the front panel to see progress.
  • Once the top GREEN LED bar in the display indicator illuminates, the battery is fully charged, and may be disconnected from the battery charger clamps.

To Disconnect

  • Switch off mains power and unplug power cord, if the last charging mode was set to lithium or other conventional lead acid batteries, the charger will retain that memory and maintain that charging profile when switched back on.
  • Disconnect the Black NEGATIVE (-) clamp from the Black NEGATIVE (-) terminal
  • Disconnect the Red POSITIVE (+) clamp from the battery Red POSITIVE (+) terminal**
  • Re-attach battery terminal protective covers if previously removed.
  • Rewind both 230v and 12V power cables back into the rear of the charger for storage.

Power Supply Mode
This battery charger is fitted with a DC power supply mode. This mode will deliver a constant 13.5 Volts at 8/12/16 Amps and can be used for powering 12V DC appliances, lighting or used for testing 12V devices. The DC power supply also has overload and short circuit protection which will cause the DC Power light to flash when protection is activated. To return to normal, press mode button once to return to charging mode, then press mode button twice to enter DC Power supply. DC power supply mode does not have memory, so disconnecting power then reconnecting it will mean the charger will return to normal charging mode.
