Frequently asked questions
How do I know if the battery is charged?
The SmartChargePro’s FULLY CHARGED LED will illuminate. If using the optional remote control the
bi-colour LED will illuminate green (solid).
The battery does not appear to be charging?
-
‘Charging’ LED does not light up (RSCPR7, RSCPR15 and RSCPR25)
-
‘LCD display displays 0.0v (RSCPR25, RSCPR35, RSCPR50 and RSCPR824)
The battery voltage is less than 2.5v. To increase the battery voltage to over 2.5v connect a set of
booster cables between the battery and a donor battery, this will allow the voltage to increase to
above 2.5v. When the battery voltage is above 2.5v reconnect the SmartChargePro
Can I use the charger as a power supply or a battery support unit?
By selecting the Power Supply mode you are able to use the charger as a power supply to run an
appliance or battery support unit to maintain battery power.
RSCPR7, RSCPR10 and RSCPR15 –
works with without the battery in vehicle
RSCPR25, RSCPR35, RSCPR50 and RSCPR824 –
Requires a battery in vehicle
What happens if I have an appliance connected to the battery while charging?
Powering an appliance while charging will impact on the SmartChargePro’s ability to accurately
measure the charge being applied. For optimum charging it is recommended to charge the battery
without an appliance connected. Power Supply mode is recommended when an appliance is
connected and drawing power
Why does Calcium mode take so long?
The calcium charging mode includes an additional charging stage, EQUALISATION. This consists of a
constant current being applied to the battery until 16v (for 12v batteries) or 32v (for 24v batteries)
is reached. This rejuvenates the battery cells and can take up to 12 hours.
Why do I need a special calcium mode?
Due to the different chemistry required to make a calcium battery a different charging algorithm is
required. Calcium batteries are also affected when deeply discharged or heavily used.
They need to be recharged by a calcium charger to fully recharge the battery and to maximise the
batteries life and performance.
