Vented Type Lead Acid Battery

Individual cells and blocks are housed in transparent plastic containers made of material that is highly resistance to chemical influences and mechanical damage.

Vented type lead acid battery.

Battery we pride ourselves on providing our customers and global partners with dependable products and reliable support information that will allow each end user to feel confident they ve made the right choice when using any of our world class deep cycle flooded lead acid and sealed agm batteries. They can be topped up when required and are therefore more tolerant to high temperature operation and over charging. Vented lead acid battery model. A vented battery can give off sixty times more gas than a vrla battery in normal use.

Vented lead acid vla group batteries are all open allowing gas to escape without any positive pressure building up in the cells. Vented lead acid batteries are commonly called flooded spillable or wet cell batteries because of their conspicuous use of liquid electrolyte figure 2. This type of battery is also used in golf carts and forklifts. Most of the battery complies with bs 6290 din40738 and iec standard.

These products are suitably used by utilities marine oil gas and petrochemical. The free electrolyte also facilitates cooling of the battery. Such treatments are rarely if ever effective. Group vented lead acid sealed lead acid vla sla or vrla.

Vented lead acid battery high performance batteries are designed to give long services life. Chemical additives have been used ever since the lead acid battery became a commercial item to reduce lead sulfate build up on plates and improve battery condition when added to the electrolyte of a vented lead acid battery. These batteries have a negative and a positive terminal on their top or sides along with vent caps on their top. Two compounds used for such purposes are epsom salts and edta.

They are maintenance free in the sense of not requiring the addition of water to offset hydrogen gas released during the charging process. Long service life of 10 to 14 years can be expected from tubular positive plates. Vrla batteries are considered to be sealed because they normally do not allow for the addition or loss of liquid. They are the most cost effective and longest lasting of the lead acid batteries.

Type ogi block range ogi stationary blocks and cells are produced using the conventional lead acid technology. Flooded lead acid batteries contain an electrolyte that is free to move around in the battery encasement. Stationary lead acid battery vented type. For many years the flooded lead acid battery has been the standard in the solar industry.

Valve regulated lead acid vrla batteries are the most widely used battery type because of their high power density and ease of use. Agm batteries must still be vented.
