Introduction

AGM batteries (Absorbent Glass Mat) represent one of the most advanced innovations in the field of lead-acid batteries. Thanks to their unique internal structure and optimized electrochemical reactions, they offer high performance, long lifespan, and maximum efficiency. In this article, we will explore how AGM batteries work, their technical advantages, and ideal applications, with a focus on the advanced solutions offered by ON LITE S.r.l.

How AGM Batteries Are Made

AGM batteries are named after the absorbent glass mat separator that holds the electrolyte in place, preventing leaks and ensuring greater stability. This innovative design reduces internal resistance and improves energy density.

Key structural features:

• Absorbed electrolyte: the glass mat completely retains the electrolyte, preventing leaks and improving the efficiency of chemical reactions.
• Optimized lead plates: thinner than those in traditional batteries, increasing the active surface area and energy storage capacity.
• Sealed structure: the batteries are fully sealed, require no maintenance, and minimize the risk of electrolyte evaporation.
• Low internal resistance: allows for high current discharge, making them ideal for applications with power surges.

Electrochemical Operation of AGM Batteries

AGM batteries use the same basic electrochemical principles as traditional lead-acid batteries, but with significant improvements thanks to their advanced construction.

During charging:

The electrolyte dissociates into hydrogen ions (H⁺) and sulfate ions (SO₄²⁻). These ions migrate toward the negative and positive plates, restoring the lead sulfate that formed during discharge.

• Optimal charging voltage: 14.4V – 14.7V (for 12V batteries)
• Charging efficiency: over 95%

During discharge:

The sulfate ions react with the lead to form lead sulfate (PbSO₄), releasing electrons that generate electric current.

• Depth of discharge (DoD): up to 80% without compromising battery life
• Nominal voltage: 12V

Discharge Performance: Why Choose an AGM Battery

AGM batteries stand out for the following characteristics:

• Voltage stability: deliver steady power throughout the discharge cycle
• High discharge capacity: suitable for engine starting and UPS systems
• Deep discharge tolerance: maintain excellent performance even with frequent deep cycles
• Vibration resistance: ideal for demanding environments such as vehicles, boats, and industrial systems
• Wide operating temperature range: from -20°C to +50°C

Applications of AGM Batteries

Thanks to their superior performance, AGM batteries are used in a wide range of sectors:

• Automotive: engine starting, Start&Stop systems, and powering electronic accessories
• Renewable energy: storage for solar and wind power systems
• UPS and backup power: emergency power for data centers, hospitals, and industrial plants
• Marine and RV: reliable off-grid energy solutions
• Telecommunications: powering repeaters and critical infrastructure
