sealed acid battery
A sealed acid battery, also known as a sealed lead-acid (SLA) battery, represents a significant advancement in energy storage technology. This maintenance-free battery system utilizes a specialized valve-regulated design that contains the electrolyte in either a gel or absorbed glass mat (AGM) form. The sealed construction prevents electrolyte leakage and eliminates the need for regular water additions, making it an ideal choice for various applications. These batteries operate through a recombination reaction where oxygen and hydrogen are converted back into water during charging, ensuring minimal gas emission and water loss. The sealed design also provides excellent resistance to shock, vibration, and position-independent operation. Modern sealed acid batteries incorporate advanced grid technologies and high-purity materials to enhance performance and longevity. They typically offer a service life of 3-10 years depending on usage conditions and are available in various capacities ranging from small backup units to large industrial installations. The technology finds widespread use in uninterruptible power supplies (UPS), emergency lighting, security systems, medical equipment, and renewable energy storage solutions.
