Key Advantages 

1. Authoritative Test-Certified Performance

Passes multiple strict tests including 10h/3h/1h rate discharge, airtightness, and safety valve performance. The terminal remains intact after 3 minutes of high-current discharge, with a sealed reaction efficiency of ≥95%—no acid mist leakage, ensuring safe use in indoor and outdoor environments. The AGM separator and high water-retention technology effectively reduce electrolyte loss, maintaining stable capacity even after long-term use.

2. Long-Lasting & Low-Maintenance Design

With 600 charge-discharge cycles and 5-8 years of design life, it outperforms ordinary lead-acid batteries in service life. The fully sealed structure eliminates the need for electrolyte refills or regular maintenance, saving time and labor costs for users. Its leak-proof and explosion-proof housing, combined with shock-resistant design, adapts to complex road conditions and harsh weather, making it reliable for mobile and outdoor applications.

 3.Versatile Application & Stable Output

Delivers consistent power output at extreme temperatures (-20℃ low temperature to 60℃ high temperature), solving the problem of capacity attenuation in harsh environments. It is widely compatible with electric tricycles, golf carts, delivery vehicles, solar energy storage systems, UPS backup power, RVs, marine equipment, and security monitoring devices. The compact size and multi-orientation installation support (vertical/horizontal/tilted) allow flexible integration into various equipment.

 4. Brand Strength & Quality Assurance

Each battery undergoes strict quality inspection before leaving the factory. The cadmium-free environmental process complies with global environmental standards, making it suitable for international markets. The patented pole group structure enhances current conductivity, ensuring strong power output for climbing and heavy-load scenarios.
