Comprehensive Guide to Rechargeable Lead Acid Batteries in China

Lead acid batteries are a crucial component in various applications, from automotive to renewable energy systems. In China, the market for rechargeable lead acid batteries is thriving, with numerous manufacturers offering a wide range of products. This guide will delve into the technical features, types, and key players in the industry, providing a comprehensive overview of rechargeable lead acid batteries.

Technical Features of Lead Acid Batteries

Lead acid batteries are known for their reliability and cost-effectiveness. They consist of lead dioxide (PbO2) as the positive plate, sponge lead (Pb) as the negative plate, and a sulfuric acid (H2SO4) electrolyte. Here are some key technical features:

Feature	Description
Voltage	Typically 2V per cell; common configurations include 6V and 12V batteries.
Capacity	Measured in ampere-hours (Ah), indicating how much current a battery can supply over a specific time.
Cycle Life	Generally ranges from 300 to 1200 cycles, depending on the depth of discharge and maintenance.
Self-Discharge Rate	Approximately 3-5% per month, which is relatively low compared to other battery types.
Temperature Range	Operates effectively between -20°C to 50°C, making it suitable for various environments.
Weight	Heavier than other battery types, which can be a consideration for portable applications.

Types of Lead Acid Batteries

There are several types of lead acid batteries, each designed for specific applications. The two main categories are flooded lead acid batteries and sealed lead acid batteries. Below is a comparison of the different types:

Type	Description	Applications
Flooded Lead Acid	Requires regular maintenance; electrolyte is accessible.	Automotive, industrial, and backup power systems.
AGM (Absorbent Glass Mat)	Sealed and maintenance-free; electrolyte is absorbed in glass mats.	UPS systems, solar energy storage, and electric vehicles.
Gel Lead Acid	Contains a gelled electrolyte; offers better resistance to vibration.	Mobility scooters, wheelchairs, and renewable energy systems.
VRLA (Valve Regulated Lead Acid)	Sealed design with a pressure relief valve; maintenance-free.	Telecommunications, emergency lighting, and security systems.
Deep Cycle Lead Acid	Designed for deep discharges; thicker plates for longer life.	Solar energy systems, electric vehicles, and marine applications.
