The battery is a solution designed to store energy that can be discharged and recharged several times.
VLRAs are batteries that do not emit gases under normal conditions and retain their tightness. This means they do not need to be installed in special ventilated rooms. Additionally, they can be installed and used in any position. Reducing the escape of electrolyte outside the housing significantly reduces corrosion in the battery's working environment and helps to protect the environment.
