When we talk about sealed lead-acid batteries (VRLA – Valve Regulated Lead-Acid), most attention goes to the plates or the electrolyte. Yet, there’s a small and often overlooked component that plays a crucial role in safety and performance: the safety valve. This tiny device is what turns a potentially hazardous battery into a safe, reliable product.In this article, we’ll explore how the VRLA valve works, its role in everyday use, and why its quality is a key indicator of the battery’s overall reliability. The Core of VRLA Technology: Gas Recombination and Safety The fundamental principle behind VRLA batteries is gas...

Introduction Uninterruptible Power Supplies (UPS) are the silent sentinels of our data centers and critical infrastructures. However, their beating heart — the sealed lead-acid (VRLA) battery bank — has a limited lifespan. Its degradation is inevitable, but not unpredictable. Waiting for a UPS to emit an annoying alarm beep or, worse, to fail during a blackout is not a maintenance strategy. It’s a calculated risk no serious professional should take. In this article, we examine the first technical and measurable signs that signal the beginning of the end for a VRLA battery. Acting on these indicators allows you to plan...

Features, Advantages, and Fields of Application of a Proven and Irreplaceable Technology In the world of backup and safety power solutions, rechargeable batteries continue to play a leading role. Among them, 1.2Ah 12V sealed lead-acid (VRLA – Valve Regulated Lead-Acid) batteries strike the perfect balance between compact size, low cost, and long-term reliability. Often referred to as “maintenance-free” or “sealed,” these batteries are designed for use without servicing, providing a robust and safe solution in a minimal footprint. But what makes them so valuable from a technical and commercial standpoint? Main Technical Features The 1.2Ah 12V VRLA batteries are a...

Lead-acid batteries are a prime example of circular economy in action, thanks to their structure and composition, which allow for the recovery of a significant percentage of the materials used. In this post, we explore how, through advanced technological processes, it is possible to reduce environmental impact and maximize resource reuse—with a particular focus on recovery rates for key materials. The Lead-Acid Battery Recycling Process The recycling process for lead-acid batteries involves several stages, each enabling the recovery of valuable materials: Material Recovery Rates Lead-acid batteries have one of the highest recycling rates among industrial products. The previously described recycling...

Lead-acid batteries are a reliable and cost-effective solution for energy storage, widely used in sectors such as automotive and emergency power systems. However, one of the main risks associated with these batteries is thermal runaway—a phenomenon that can compromise both the safety and lifespan of the storage system. In this article, we’ll explore the causes of thermal runaway, its effects, and the best practices to prevent it. What Is Thermal Runaway? Thermal runaway is an uncontrolled process in which a battery’s temperature increases progressively due to internal factors, potentially leading to severe failures, electrolyte leakage, or even explosions. The issue...
