The ECELL EC Series is a general-purpose VRLA (Valve Regulated Lead Acid) battery designed for reliable backup power and high-rate discharge performance. Built with advanced AGM (Absorbent Glass Mat) technology and ultra-high purity (99.996%) lead plates, the EC Series ensures superior energy density, exceptional corrosion resistance, and strict consistency for critical applications.
・ 99.996% High-Purity Lead: Features premium 99.996% pure lead plates to minimize internal impurities, significantly reducing self-discharge and extending service life.
・ Maintenance-Free Operation: Sealed VRLA construction allows for safe operation in any position without the need to add water or electrolyte.
・ High-Rate Discharge Performance: Optimized plate design and low internal resistance deliver high power output, perfect for critical UPS demands.
・ Long Service Life: Heavy-duty lead-calcium grids resist corrosion, providing a design life of 5-10 years in float service applications.
・ Low Self-Discharge: High-purity raw materials ensure a self-discharge rate of less than 3% per month (at 25°C), allowing for long shelf storage.
・ High-Power & Durable：Designed with military-gradehigh-performance AGM separators, optimized for high-current discharge. Capable ofhandling large instantaneous loads to meet short-term high-power demands.
・ Stable & Reliable Energy：Combining high energy densitywith excellent discharge efficiency, delivering stablepower-ideal for precision equipment and ensuring the reliable operation of criticalsystems.
・ 15-Minute Colden Backup：High-tin, low-calcium alloy gridspaired with a high-power leadpaste formula enable instanthigh-current output, providing dependable emergency backup for short-duration power needs.
・ Safety & Reliability: Equipped with explosion-proof safety valves and rugged ABS containers (UL94-V0 optional) to ensure operational safety.
