It seems like my flooded batteries are losing water over time.
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.
When charging, my flooded batteries are emitting gas.
During charging, hydrogen gas is generated within the battery. The gas
bubbles stir the battery acid, allowing it to receive a fuller state of charge.
Important:
Ensure batteries are in a well-ventilated space.
My voltmeter shows a different reading than the GP-PWM-10-FM
display.
The meter value on the GP-PWM-10-FM 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 GP-PWM-10-FM display and the battery voltage measured at the
battery terminals. When troubleshooting using a voltmeter, check both
the battery voltage at the GP-PWM-10-FM 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. Consult the Suggested Minimum Wire
Gauge chart in
Section 5
for wiring suggestions and check all
connections.
