Q. What if I have an appliance connected to the battery whilst charging?
A. Powering an appliance while charging your battery will impact on the battery chargers
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.
Q. Can I select a different battery chemistry for charging my battery?
A. Yes the battery chemistry selection can be different to your battery type if the charge
voltages match the battery manufacture’s recommendations.
Q. Why does CALCIUM mode take so long to charge?
A. 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.
Q. Why do I need a special Calcium mode?
A. 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.
Q. What is a Calcium battery?
A. 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.
