Why Lead-Acid Batteries Remain a Cornerstone of Energy Storage

Lead-acid batteries, one of the oldest rechargeable battery technologies, continue to dominate energy storage solutions across industries. Despite newer alternatives, their reliability, cost-effectiveness, and adaptability make them indispensable. Whether for grid stabilization, renewable integration, or backup power, understanding the types of lead-acid battery energy storage is critical for optimizing performance.

Key Types of Lead-Acid Batteries

1. Flooded Lead-Acid (FLA) Batteries

Often called "wet-cell" batteries, FLA systems use liquid electrolytes. They're widely used in:

• Telecom backup power
• Off-grid solar installations
• Industrial forklifts

While requiring regular maintenance, their low upfront cost ($80–$150/kWh) keeps them popular.

2. Valve-Regulated Lead-Acid (VRLA) Batteries

VRLA batteries are sealed and maintenance-free, split into two subtypes:

• AGM (Absorbent Glass Mat): Ideal for high-power applications like UPS systems.
• Gel Batteries: Suited for deep-cycle uses, such as solar storage in harsh climates.

A 2023 study showed VRLA batteries account for 62% of new lead-acid deployments in renewable projects.
