Production Process
Using virgin lead with a purity of 99.999% as the core material reduces battery self-discharge from the source and effectively extends battery life.
The dual-production line automated die-cast lead-calcium alloy grid has excellent conductivity and corrosion resistance, laying the foundation for stable battery output.
Precision grinding of lead powder ensures uniform particle size, guaranteeing stable internal reactions within the electrode plates and resulting in higher battery capacity.
Large-scale, sealed drying equipment uses constant temperature dehydration to completely eliminate moisture from the plates and avoid potential internal battery problems.
Positive and negative plates are stored separately and managed in a standardized manner to avoid mixing and ensure stable performance of each batch of batteries.
The automated equipment completes the sealing of the electrode plates and separators with high precision, and the shell is sealed, providing excellent leak-proof capability.
The first charge and discharge cycle is performed to activate the active materials on the plates and calibrate the battery's rated capacity to ensure that the power output meets factory standards.
The equipment precisely adds electrolyte, ensuring a uniform amount to each battery and preventing performance degradation caused by overfilling or underfilling.
Finished products that pass the charge and discharge tests are centrally stored in designated areas, with sufficient inventory reserved to handle large-volume overseas orders.
Finished products are neatly stacked on pallets and reinforced with wrapping film to prevent collisions and tipping during long-distance sea transport, thus reducing the breakage rate.
Forklifts and assembly lines work together to load containers, reducing human-caused damage and significantly improving loading and shipping efficiency.
Full container loads are delivered directly to ports around the world, ensuring a stable and efficient logistics supply chain that continuously supplies distributors worldwide.
