Voltage Disparity Table
Below is a guide to Crankenstein’s voltage limitations when the unit is in either 12V or 24V mode. The built-in volt meter
will measure and display your vehicle’s battery voltage
(VB)
in the lower right corner of the OLED screen. If the battery
voltage does not align with the chosen jump mode, you will receive a warning message (refer to the OLED Message Index
on pages 12 - 16 for a list of warning messages).
12V MODE
0.5V < VB < 15V
If your vehicle’s battery voltage is between 0.5V and 15V it is within
a normal operating range.
VB < 0.5V
If your vehicle’s battery voltage is less than 0.5V, Crankenstein will
not automatically awaken. To jump, you will need to select the 12V
Mode to power on the unit.
VB > 15V
If Crankenstein is measuring a voltage above 15V, you will get a
warning message to alert you that it is likely you are jumping a
24V system. The unit will automatically switch to 24V mode in this
instance.
24V MODE
15V < VB < 26V
If your vehicle’s battery voltage is between 15V and 26V it is within a
normal operating range.
VB < 0.5V
If your vehicle’s battery voltage is less than 0.5V, Crankenstein will
not automatically awaken. To jump, you will need to select the 24V
Mode to power on the unit. Crankenstein will take a few minutes to
“trickle charge” your battery to bring the voltage up to 2.0V before
you can jump. Note: If your vehicle’s battery voltage is not able to
reach/hold 2V, you will be unable to jump start.
2V < VB < 15V
If your vehicle’s battery voltage is between 2V and 15V, you may be
connected to a 12V system (select 12V Mode to switch to proper
mode) or you are jumping a weak 24V battery (select 24V Mode to
bypass the warning message).
