Lead-acid energy storage batteries are a well-established and cost-effective energy storage solution. With a long history of safe use, mature manufacturing technology, and wide availability, they continue to play a vital role in both residential and industrial energy storage systems.
1. Off-grid Photovoltaic Systems
In remote areas where access to the grid is limited or nonexistent, lead-acid batteries are indispensable in storing solar energy generated during the day for use at night or during cloudy periods. This enables a more stable and reliable off-grid energy solution.
Key Benefits:
① Stable energy output during intermittent sunlight ② Low cost and easy maintenance ③ Compatible with most solar inverters
2. Uninterruptible Power Supply (UPS) Systems
Data centers, hospitals, banks, and other critical facilities require seamless power supply to prevent data loss, operational disruptions, or safety risks. Lead-acid batteries act as the core energy buffer in UPS systems, ensuring continuous operation during power interruptions.
3. Backup Power for Communication Base Stations
Stable communication is critical, especially in disaster-prone or power-unstable regions. Lead-acid batteries ensure uninterrupted signal transmission by providing immediate backup power to base stations.
Typical Usage:
① 4G/5G base stations ② Rural or mountainous areas ③ Emergency communication systems
4. Electric Vehicles and Light E-mobility
Lead-acid batteries are commonly used in electric bicycles, scooters, low-speed vehicles, and certain forklifts. Their low upfront cost and simple charging requirements make them a popular option in many developing countries.
5. Emergency Lighting and Safety Systems
During emergencies such as fires, earthquakes, or blackouts, lead-acid batteries provide reliable power for emergency lighting, evacuation guidance systems, and fire safety alarms, ensuring public safety in commercial and residential buildings.
6. Industrial and Backup Applications
Mobile communication base stations require round-the-clock power, especially in remote or unstable grid areas. Lead-acid batteries provide reliable backup power to ensure continuous and stable network operation.
With advantages such as affordability, long cycle life, and ease of recycling, lead-acid batteries remain a mainstream solution for many energy storage applications. As technology advances, newer models with enhanced energy density and safety features continue to emerge, extending the applicability of lead-acid batteries in both traditional and emerging markets.
