Discover the working principle of Valve Regulated Lead Acid (VRLA) batteries: Basic Operation: VRLA batteries operate on the principle of electrolysis. Within the sealed battery, two lead plates immersed in a sulfuric acid solution facilitate a chemical reaction. One plate is coated with lead dioxide, while the other is made of spongy lead.
This dominance is particularly evident in the field of Uninterruptible Power Supplies (UPS). A Valve Regulated Lead-Acid Battery (VRLA battery) is a type of lead-acid battery characterized by its sealed, maintenance-free design. It does not require the addition of acid or water during its service life.
Freudenberg Sealing Technologies has introduced a new generation of DIAvent valves, which allow reaction gases to escape from damaged lithium-ion batteries. The valves also maintain the continuous pressure compensation required for normal battery operation.
A VRLA, or Valve Regulated Lead Acid battery is a rechargeable lead acid battery. that doesn’t require regular maintenance like topping off water levels, VRLA batteries are sealed and do not allow for the addition or loss of liquid. Its design includes a safety valve that will open only if internal pressure rises to a dangerous level.
The valves also maintain the continuous pressure compensation required for normal battery operation. If a battery gets damaged, liquid electrolytes can escape into the battery housing as hot gases. These must then be released into the environment very rapidly and in a controlled process through a pressure relief valve.
At the same time, every battery housing needs controlled venting to compensate for fluctuating air pressure during normal operation. This is necessary not only when driving uphill and downhill, but also because the air in the housing heats up during power input and output.
