1. Industry-Leading Long Service Life Design
   Specially formulated calcium-lead thick plate grid drastically slows corrosion and capacity attenuation. Delivers ultra-long floating standby life, perfectly matching 10+ year service cycle demands of telecom machine rooms and large UPS data centers, reducing frequent battery replacement costs for clients.
2. Non-Spillable Fully Sealed Maintenance-Free Construction
   Hermetic safety valve sealing structure locks electrolyte completely inside the housing. Zero risk of acid leakage, no regular water topping-up required. Safe for indoor cabinet stacking installation without corrosion to racks, circuit boards and communication equipment.
3. Stable High-Current Discharge for Heavy Loads
   Low internal resistance structure ensures steady large-current output during grid power outages. Supports full-load startup of high-capacity industrial UPS and uninterrupted signal transmission for telecom base stations, eliminating voltage drop risks to critical equipment.
4. Standardized Cabinet Size for System Integration
   Universal 328*172*222mm footprint fits most mainstream 100Ah battery racks for telecom and UPS systems. Easy series/parallel assembly to build large energy storage battery banks without custom cabinet modification.
5. Wide Temperature Adaptability & Low Self-Discharge
   Advanced raw material formula achieves ultra-low self-discharge rate during long idle storage. Maintains consistent performance across wide indoor temperature ranges, reliable for year-round continuous operation in data rooms, telecom shelters and power stations.
6. Global Authorized Certifications for Smooth Export
   Comes with UL and CE certification, and fully complies with EU REACH hazardous substance regulations. Passed strict third-party electrical safety tests, enabling hassle-free customs clearance for bulk shipments to Europe, North America, Southeast Asia, Middle East and other regions.
