Q1. It seems like my flooded batteries are losing water over time.
A. Flooded batteries may need to have distilled water added periodically to replace fluid loss during charging. Excessive water loss during a short period of time indicates the possibility of overcharging or aging batteries. 


Q2. When charging, my flooded batteries are emitting gas.
A. During charging, hydrogen gas is generated within the battery. The gas bubbles stir the battery acid allowing it to receive a more full state of charge. Ensure batteries are in a well-ventilated space.


Q3. My voltmeter shows a different reading than the charge controller display
A. The meter value on the charge controller display is an approximate reading intended for indication purposes only. There is an 
approximate 0.1 volt inherent error present that may be accentuated when compared with readings from another voltmeter.

There may be a slight difference between the battery voltage displayed on the charge controller display and the battery voltage measured at the battery terminals. When troubleshooting using a voltmeter, check both the battery voltage at the controller terminals and battery voltage at the battery terminals. If a difference of more than 0.5 volts is noted, this indicates a large voltage drop possibly caused by loose connections, long wire runs, small wire gauge, faulty wiring, a faulty voltmeter or all the above. Check all connections.
