What Is a Sealed Lead Acid Battery and How Does It Work?

A sealed lead acid (SLA) battery is a rechargeable battery that uses lead and lead oxide plates submerged in a sulfuric acid electrolyte. It is designed to be maintenance-free, as the acid is absorbed in a glass mat or gel, preventing spills and leaks.

According to the Battery University, sealed lead acid batteries are widely used due to their durability and cost-effectiveness, offering performance suited for various applications.

SLA batteries are known for their robustness, deep cycle capabilities, and ability to deliver high bursts of current. They are commonly used in uninterruptible power supplies (UPS), vehicles, and emergency lighting systems. The sealed design limits gas emissions during charging, enhancing safety and usability.

The International Electrotechnical Commission (IEC) describes SLA batteries as having low self-discharge rates, making them suitable for long-term storage. Their design allows for different configurations, including sealed flooded, absorbed glass mat (AGM), and gel cells.

Environmental factors such as temperature and charging practices affect SLA battery performance. Overcharging or exposure to extreme heat can reduce battery lifespan and efficiency.

Studies estimate that the global SLA battery market will grow at a compound annual growth rate (CAGR) of 6.6%, reaching over $12 billion by 2026, according to Research and Markets.

The improper disposal of SLA batteries can lead to environmental contamination and health hazards due to lead and sulfuric acid.

Sustainable practices call for recycling programs and proper disposal guidelines to mitigate the risks associated with SLA batteries. Organizations like the Rechargeable Battery Association advocate for educating consumers about battery care and disposal.

Strategies to enhance SLA battery sustainability include using recycling facilities, promoting battery collection programs, and investing in advanced technologies that improve battery efficiency and reduce lead usage.
