Introduction

Flooded lead-acid batteries are among the most established and commonly used battery technologies. These batteries are characterized by their lead-based electrodes submerged in a liquid electrolyte solution. This design allows for robust energy storage, making them ideal for various applications despite being one of the oldest rechargeable battery types.

Characteristics of Flooded Lead-Acid Batteries

The core components of a flooded lead-acid battery include lead dioxide (PbO₂) as the positive plate, sponge lead (Pb) as the negative plate, and a sulfuric acid (H₂SO₄) solution as the electrolyte.

• Chemistry: The electrochemical reactions enable charge and discharge cycles, providing effective energy storage.
• Cycle Life: Typical cycle life ranges between 200 and 1,200 cycles, subject to depth of discharge and maintenance practices.
• Voltage: Nominal cell voltage is approximately 2 volts per cell, with battery packs typically consisting of 6-12 cells.

Performance Metrics

Key performance indicators for flooded lead-acid batteries include capacity, efficiency, temperature, and discharge rate.

• Capacity: Measured in ampere-hours (Ah), typical capacities range from 25Ah to 1000Ah.
• Efficiency: Coulombic efficiency between 70% to 85%, depending on usage conditions.
• Operating Temperature: Optimal operating temperatures range from 20°C to 25°C for best performance.
• Discharge Rate: Can accommodate high discharge rates, ideal for situations requiring substantial power output.

Applications

Flooded lead-acid batteries are versatile and are utilized in numerous applications including:

• Automotive: Widely used in vehicles for starting, lighting, and ignition (SLI) purposes.
• Industrial: Employed in backup power systems and for powering equipment in warehouses.
• Renewable Energy: Serve as storage solutions for solar and wind energy systems.

Maintenance and Safety Tips
