A valve regulated lead acid (VRLA) battery is also known as sealed lead–acid (SLA) battery is a type of lead-acid battery. In this type of battery, the electrolyte that does not flood the battery but it’s rather absorbed in a plate separator or silicon is added to form a gel.
Current projects that have been authorized by the IEEE SA Standards Board to develop a standard. This recommended practice provides recommended design practices and procedures for storage, location, mounting, ventilation, instrumentation, preassembly, assembly, and charging of valve-regulated lead-acid (VRLA) batteries.
Valve-regulated lead acid batteries must not be topped up with water through their entire life. The valves must not be opened because the access to oxygen in the air discharges the cells. BAE VRLA Gel batteries may be stored without further charging only for a limited period because of self-discharging and related chemical processes.
Store batteries indoors in a clean, dry and cool location. DO NOT stack pallets. Damage may occur and the warranty will be voided. Valve-regulated lead acid batteries must not be topped up with water through their entire life. The valves must not be opened because the access to oxygen in the air discharges the cells.
In all lead acid batteries, when a cell discharges charge, the lead and diluted sulfuric acid undergo a chemical reaction that produces lead sulfate and water. When the battery is put on the charger, the lead sulfate and water are turned back into lead and acid. The charging current is very important for this process to take place.
In ordinary flooded lead acid batteries, these gases are allowed to escape hence the need to have distilled water added from time to time to replace the lost water. In contrast, VRLA batteries retain the generated gases within the battery as long as the pressure remains within safe levels.
