FAQs.
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.
