HOW DO I KNOW IF THE BATTERY IS CHARGED?

The charger’s FULL LED will illuminate (solid). Alternatively, use a Battery Hydrometer (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 BULK LED DOES NOT COME ON.

Sometimes batteries can be flattened to the point where they have very little or no voltage. This can happen if a small load is left on for a long period, such as a map reading light left on for a week or more. Projecta 6 Stage chargers are designed to charge from as little as 3.0 Volts.

If the battery voltage is below 3.0 Volts, use booster cables to connect the flat battery to another battery so that it receives more than 3.0 Volts. The charger can then begin charging, after which the booster cables can be removed.

CAN I USE THE CHARGER AS A POWER SUPPLY?

No. Projecta 6 Stage chargers only supply power to the battery clips when they are correctly connected to a battery. This prevents sparks and protects against incorrect connection. As a result, the charger cannot be used as a ‘Power Supply’.

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

Coloured LEDs indicate the different charging stages. Refer to the “LED Charge Indicators” section of the booklet for details.

WHY DOES CALCIUM MODE TAKE SO LONG TO CHARGE?

Calcium batteries require an extra charging stage known as ‘Equalisation’, where a constant current is applied until 16 Volts is reached. This rejuvenates the battery cells and can take up to 12 hours.

WHY DO I NEED A SPECIAL CALCIUM MODE?

Calcium batteries use different chemistry and therefore require a different charging algorithm. When deeply discharged or heavily used, they need a Calcium charger to fully recharge and restore battery performance and lifespan.

WHAT IS A CALCIUM BATTERY?

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

Benefits include:
i. Lower internal resistance for improved CCA performance.
ii. Ability to withstand higher engine bay temperatures.
iii. Low self-discharge rate, offering a shelf life up to four times longer than a Lead–Lead battery.
