No Battery Detected
The charger has detected that no battery is connected. 
Connect a battery to the unit to clear this fault.
 If a battery IS connected and you see this fault, this 
usually means the battery is completely discharged. 
Try switching the unit to Power Supply mode for a few 
minutes and then back to Charger mode to see if it will 
return the battery to life. If it doesn’t, the battery is defec-
tive and will have to be replaced.
Battery Low Voltage Indication
If the battery is seriously discharged, and the charger 
voltage drops below 85% of nominal (ie. 10V for a 12V 
charger), the charger will show this display until the 
battery voltage exceeds 85% of nominal.
