Quality is built into every stage of our battery manufacturing process.
JYC Battery applies systematic quality control from raw materials and production processes to final performance testing, helping ensure consistent quality, reliable performance, and long service life.

01. Material Inspection

Quality Starts with Every Material

Before production begins, key raw materials and components are carefully inspected to ensure they meet defined quality and performance requirements.

• Lead Purity 
• AGM Porosity 
• Compressive Strength 
• Sulfuric Acid Purity 
• Safety Valve 

02. Product Inspection

Quality Controlled Throughout Production

During manufacturing, JYC conducts process and product inspections at critical production stages to identify potential issues before batteries move to final testing.

• Grid Test 
• Plate Weight Test 
• Short Circuit Test 
• Internal Resistance Inspection After TTP Welding 
• Airtightness Test After Heat Sealing 
• Charging Test 
• Random Test
• High Current Test During Packaging 

03. Performance Inspection

Performance Verified Before Delivery

Finished batteries undergo performance testing to verify their electrical characteristics, capacity, durability, and ability to perform reliably under different operating conditions.

• General Capacity Test 
• High Current Test 
• Cycle Test 
• CCA Test
• High & Low Temperature Test 
• Internal Resistance Test 
• Voltage Test
