Introduction
The internal structure of a lead acid battery plays a critical role in its performance, lifespan, and reliability. Different designs—such as AGM, Gel, OPzV, and OPzS—are all based on variations of the same fundamental structure.
Main Components
1. Positive Plate
- Made of lead dioxide
- Responsible for energy generation
2. Negative Plate
- Made of sponge lead
- Supports chemical reactions
3. Electrolyte
- Sulfuric acid solution
- Enables ion movement
4. Separator
- Prevents short circuit
- Allows ion flow
5. Battery Container
- Protects internal components
- Prevents leakage
Plate Design Types
Flat Plate
- Lower cost
- Shorter lifespan
Tubular Plate
- Longer lifespan
- Better deep cycle performance
Electrolyte Types
Liquid Electrolyte (Flooded)
- Requires maintenance
Gel Electrolyte
- Maintenance-free
- Better deep cycle
AGM Structure
- Absorbed electrolyte
- Better high-current performance
