Flooded Valve Regulated Lead Acid Batteries (VRLAB)

Flooded Valve Regulated Lead Acid Batteries (VRLAB)

                  The oldest types of lead acid batteries are flooded cell types. These have been around for decades and evolved from wooden box models into the plastic valve regulated models on the market today. The electrolyte in these batteries is liquid sulfuric acid solution. This stuff is pretty corrosive and has destroyed more than a few sets of clothes and pieces of RV gear. VRLA flooded batteries generate and vent dangerous explosive gases through their valve regulation and must be vented to the outside world. These batteries also acid "mist" during charging and discharging. This leads to the corrosion of their terminals, and often-acid damage to surrounding surfaces. (look at your car battery for an example) VRLA Flooded batteries must be installed upright, can leak that acid, and require regular watering. Should they fail to be watered, they will not perform to spec. That all being said, they are also the least expensive type and therefore are the choice of many renewable and RV owners.
