Overview
YANASE Battery is a Japanese lead-acid battery manufacturer established in the mid-20th century, specializing in reliable power solutions for industrial and commercial sectors. The brand is recognized for its rigorous quality control and adherence to JIS standards. Products include sealed AGM (Absorbent Glass Mat), gel electrolyte, and traditional flooded batteries, catering to diverse voltage (6V/12V) and capacity (5Ah–200Ah) requirements. Common applications range from UPS systems to heavy machinery.
Structure and Working Principle
YANASE batteries utilize lead dioxide (PbO₂) positive plates and sponge lead (Pb) negative plates immersed in sulfuric acid electrolyte. AGM variants immobilize the electrolyte in fiberglass mats, enabling spill-proof operation. During discharge, chemical reactions between the plates and electrolyte generate electricity, reversing during recharge. Gel batteries use silica-thickened electrolyte for deeper cycle tolerance, while flooded types require periodic water replenishment.
Key Features
1. **Longevity**: 500–1,200 cycles at 50% depth of discharge (DOD), depending on series. 2. **Safety**: Flame-retardant casings and pressure relief valves in sealed models. 3. **Temperature Resilience**: Operates from -20°C to 50°C. Industrial-grade models feature thick plates for high-current discharge, making them suitable for forklifts and solar storage. Self-discharge rates are as low as 3% per month.
Application Areas
**Industrial**: Backup power for factories, mining equipment, and railway signaling. **Telecom**: Base station battery banks. **Automotive**: Starter batteries for trucks and buses. AGM batteries dominate emergency lighting due to maintenance-free operation, while gel types excel in off-grid solar systems for their deep-cycle capability. Flooded batteries remain cost-effective for stationary applications.
Maintenance and Precautions
For AGM/gel batteries: Regularly check terminals for corrosion and ensure chargers use correct voltage profiles (typically 14.4–14.8V for 12V systems). Avoid exceeding 25°C ambient temperature to prolong lifespan. Flooded batteries require distilled water top-ups when electrolyte levels drop below plate tops. Always use PPE when handling acid. Storage should be in cool, dry environments at 40–70% state of charge.
B2B Procurement Guide
**MOQ**: Commonly 10–50 units for standard models; OEM customization available. **Lead Time**: 4–8 weeks for bulk orders. **Certifications**: Look for CE, UL, and JIS markings. Verify compatibility with existing systems—key parameters include dimensions, terminal type (F-type/L-type), and CCA (Cold Cranking Amps) for automotive use. Partner with authorized distributors to avoid counterfeit products.
