We need to set the Efficiency. Typically on a flooded battery this will be
between 94 and 96%. On a sealed battery it can be higher. If there is any
question you should shoot for a lower efficiency, not a higher one. You can
also contact your battery supplier for help with that value. After both of
these are set, press Enter to save them. Next, press the upper right button,
(Right Soft Key) to continue with setup.
Figure 7 – Whizbang jr. “Setup-2” Screen
On the second setup screen “figure 7” we need to set the battery temperature we
reference to for temperature compensation for capacity change and voltage
adjustment. As a battery changes in temperature, its apparent capacity changes
and the voltage we charge it to needs to change. If the battery temperature is
above the “Reference Point” (Hot) we gain capacity and lower the charge
voltage. If the battery temperature is below the reference point (Cold) we lose
capacity and raise the charge voltage. Most standard batteries use 25 Degrees
Celsius as their “Reference Point”. If your battery uses something other than
25C for a reference value, this is where you would set it.
We also have to set the percentage of capacity lost or gained for every degree
Celsius we are below or above the reference point. This value can be set from 0
to 3%, where 0 is disabled. Typically a lead acid battery is 1% per degree C.
When both values are set press Enter to save these changes and then press
Status to return to the home screen.
For help with any of these battery specific values, please contact your battery
supplier/manufacturer.
Also note that on the Home screen the Charge stage message in the bottom right
corner will toggle between the current stage and the actual state of charge
percentage after it goes to float for the first time.
WHIZBANG JR. ASSISTED CHARGING:
One feature of the Whizbang Jr. is the ability to end an Absorb charge based on
Ending Amps. In this mode, if the battery current falls below a programmable
threshold for one minute, the Classic will go to Float, meaning that the
batteries have been fully charged.
To enable Whizbang Jr. assisted charging, select “CHARGE” from the main menu.
Select “ADVANCED.” Press the soft-left key until the annunciator above it reads
