Quality Control and AGM Technology

AJC strictly adheres to international quality standards, implementing comprehensive testing and procedures from raw materials to final production. This ensures customers receive excellent products with consistent quality.

At the core of AJC batteries is Absorbed Glass Mat (AGM) technology. Puncture-resistant glass mat separators absorb all electrolytes, lowering internal resistance and resulting in effective high-rate, short-term power.

Lead Purity and Battery Care

AJC uses only brand-new, 99.998% pure lead. Lead impurities can significantly decrease battery performance and lifespan, but AJC's strict manufacturing process eliminates trace impurities, yielding high-quality, dependable batteries.

To maintain optimal SLA battery performance: - Recharge after each use to prevent decline - Avoid complete discharges - Periodically check terminals for corrosion or wear - Always store the battery fully charged in a cool, dry place
