HOW DO I KNOW IF THE BATTERY IS CHARGED?

The charger’s FULLY CHARGED LED will illuminate (solid) and the remote’s bi-colour LED will illuminate green (solid). Alternatively use a Battery Hydrometer (Projecta Part No. BH100). A reading of 1.250 or more in each cell indicates a fully charged battery.

I HAVE CONNECTED THE CHARGER PROPERLY BUT THE LCD DISPLAY READS 0.0 (ZERO) VOLTS AND DOES NOT APPEAR TO BE CHARGING.

In some cases batteries can be flattened to the point where they have very little or no voltage. This can occur if a small amount of power is used for a long time, for example a map reading light is left on for a week or more. Projecta Intelli-Charge are designed to charge from as little as 1.0V (12V) or 2.0V (24V).

If the voltage is lower than the voltages stated above use a pair of booster cables to connect between two batteries to provide more than 1.0V (12V) or 2.0V (24V) to the battery being charged. The charger can then start to charge the battery and the booster cables can be removed.

CAN I USE THE CHARGER AS A POWER SUPPLY?

Power Supply mode is designed to operate as a float charge to maintain a battery when running a load or appliance from the battery. Power Supply will only operate when connected to a battery.

HOW CAN I TELL WHAT STAGE THE BATTERY CHARGER IS IN?

The LCD screen and coloured LEDs indicate the various stages of charging. Refer to pages 10 (“LED Charge Indicators”) and 11 (“Charging Instructions – Step 7”).

WHAT HAPPENS IF MY BATTERY CHARGER IS IN DESULPHATION MODE OR SOFT START MODE, BUT I WANT TO START BULK CHARGING?

Desulphation mode is time limited to 6 hours and Soft Start is limited to 1 hour. If you cannot wait for the battery charger to move through these stages you can select Power Supply mode to charge the battery. After an hour of charging in Power Supply mode, there should be sufficient charge in the battery to bypass both Desulphation and Soft Start. Select the correct battery chemistry type to continue charging the battery. Whilst in Power Supply mode the charger will output a full current up to 13.8 Volts (12V) or 27.6 Volts (24V).

WHAT IF I HAVE AN APPLIANCE CONNECTED TO THE BATTERY WHILST CHARGING?

Powering an appliance while charging your battery will impact on the battery charger’s ability to accurately measure the battery’s response to the charge being applied. The battery charger has been designed to accommodate this situation although not recommended.

For optimum charging it is recommended to charge without any appliance load on the battery. Power Supply mode is recommended when an appliance is connected to a battery and is drawing power.

CAN I SELECT A DIFFERENT BATTERY CHEMISTRY FOR CHARGING MY BATTERY?

Yes the battery chemistry selection can be different to your battery type if the charge voltages match the battery manufacturer’s recommendations.

WHY DOES CALCIUM MODE TAKE SO LONG TO CHARGE?

To fully charge a Calcium battery, the battery requires an extra charging stage called ‘Equalisation’. This consists of a constant current being fed into the battery until 16 Volts (12V) or 32 Volts (24V) is reached. This rejuvenates the battery cells. This charging stage can take up to 12 hours.

WHY DO I NEED A SPECIAL CALCIUM MODE?

Because of the different chemistry used to make a Calcium battery, a different charging algorithm (or technique) is required. Calcium batteries are also affected when deeply discharged or used heavily. They need to be recharged by a Calcium charger to fully recharge the battery and to maximize the battery’s life and performance.

WHAT IS A CALCIUM BATTERY?

Calcium batteries are lead acid batteries that have had calcium added to the lead plates, either to one plate (called Calcium Hybrid) or to both plates (called Calcium–Calcium).

The added calcium provides a number of benefits:
i. Lower internal resistance which provides a small increase in CCA performance.
ii. The ability to withstand higher engine bay temperatures.
iii. Low self discharge rate, which increases the shelf life, typically 4 times longer than a Lead–Lead battery.
