Vrla Batteries
VRLA stands for valve-regulated lead-acid and is the designation for low-maintenance lead-acid rechargeable batteries. Because of their construction, VRLA batteries do not require regular addition of water to the cells.[1] VRLA batteries are commonly further classified as:
• Absorbed glass mat battery
• Gel battery
These batteries are often colloquially called sealed gel batteries, but they always include a safety pressure relief valve. As opposed to vented (also called flooded) batteries, a VRLA cannot spill its elecrolyte if it is inverted. Because VRLA batteries use much less electrolyte (battery acid) than traditional lead-acid batteries, they are also occasionally referred to as an “acid-starved” design.
The name “valve regulated” does not wholly describe the technology; these are really “recombinant” batteries, which means that the oxygen evolved at the positive plates will largely recombine with the hydrogen ready to evolve on the negative plates, creating water—thus preventing water loss. The valve is strictly a safety feature in case the rate of hydrogen evolution becomes dangerously high.
One result of this design is a much higher ratio of power to “floorspace” than large, flooded type battery systems; another is a high-rate power capacity, though of relatively short duration. As a result, VRLA batteries are frequently employed in UPS (uninterruptible power supply) or other high-rate applications. Long duration applications such as telecommunications are not as well-suited to VRLA batteries, as there are other, more applicable battery designs available.
Significant improvements to VRLA battery cells can be made with the addition of a catalyst for recombining oxygen and hydrogen gasses within the cells as disclosed in U.S. Application Ser. No. 09/022,336 filed Feb. 11, 1998, and which is hereby incorporated by reference. One preferred method of adding catalyst to VRLA battery cells is to couple the catalyst with the pressure relief valve, sometimes referred to as a pressure relief vent or pressure relief vent cap, which provides a convenient means of retrofitting existing cells as well adding catalyst to new cells. A novel catalyst device for use with pressure relief valves is disclosed in U.S. Application Ser. No. 09/022,336. While the addition of catalyst provides significant improvement in the performance and of life of VRLA cells, additional improvements to the catalyst itself, particularly with the structures and devices that support or house the catalyst, are believed necessary to gain the full benefits of the catalyst.
