12V 4ah Rechargeable Motorcycle Battery

Product Description

Product Description**Production Process of Sealed Maintenance-Free Lead-Acid Motorcycle Batteries**
1. **Raw Material Preparation**
The first step in producing sealed maintenance-free lead-acid batteries involves selecting high-quality raw materials, including high-purity lead ingots, specially formulated sulfuric acid electrolyte, fiberglass separators, and durable, corrosion-resistant plastic casings. These materials undergo strict quality inspections to ensure they meet production standards.
2. **Lead Powder Production and Oxidation**
Lead ingots are processed into lead powder using specialized equipment, then oxidized to create lead oxide. This is a crucial step to ensure the battery's performance.
3. **Plate Manufacturing**
Lead oxide is mixed with sulfuric acid to create the active material, which is then applied to lead grids to form positive and negative plates. These plates are then dried in a curing chamber to enhance their stability and conductivity.
4. **Plate Assembly and Welding**
The positive and negative plates, along with fiberglass separators, are assembled in a specific order to form the battery cell. Fiberglass separators are highly absorbent, retaining the electrolyte while preventing contact between the positive and negative plates. The assembled plates are then welded together to create a solid unit.
5. **Battery Cell Assembly**
The assembled plate units are placed into specially designed plastic casings and filled with precisely measured sulfuric acid electrolyte. The battery is then sealed to prevent any acid leakage. This sealed design ensures the battery remains maintenance-free throughout its lifespan.
6. **Initial Charging (Formation Process)**
The battery undergoes an initial charge, known as the "formation process," where an electric current activates the electrode materials and establishes a stable electrochemical reaction. This process can take several hours to days, ensuring the battery's long-term stability.
7. **Safety Valve Design and Installation**
To ensure safety, a specially designed safety valve is installed before sealing the battery. These valves automatically release gas if internal pressure becomes too high, preventing casing rupture while keeping external air out to maintain internal stability.
8. **Testing and Quality Control**
Each battery undergoes rigorous testing before leaving the factory, including capacity testing, voltage measurement, internal resistance testing, sealing checks, and high/low temperature performance tests, ensuring reliable operation under all conditions.
9. **Finishing and Packaging**
After passing all tests, the battery is cleaned to remove any residue from the production process and undergoes a final visual inspection to ensure it is free of defects. The battery is labeled with detailed information, including the production date, specifications, and usage instructions, and is then carefully packaged to prevent damage during transport.
10. **Storage and Transportation**
The finished batteries are stored in controlled environments to maintain optimal performance. We use secure shipping methods to ensure that each battery is delivered intact and in perfect condition to our customers.
Through these meticulous production steps, our sealed maintenance-free lead-acid motorcycle batteries offer high performance, long life, and the convenience of maintenance-free operation, ensuring exceptional reliability in all environments.Specification
