Technological Breakthrough

The Lead-Crystal patent technology adopted by lead-crystal batteries is a patented technology independently invented by EGE Company. The lead-crystal electrolyte is a new type of composite electrolyte with a unique formula developed by us, which has replaced the traditional sulfuric acid solution. This electrolyte overcomes a series of problems in lead-acid batteries, such as the lack of active substances, rapid water loss, and acid stratification under water, significantly improving performance and safety of the battereis. It has also solved the problems of high internal resistance, weak matching with AGM separators, slow electrode reaction speed, easy cracking and irreparable nature of gel batteries.

The application of composite electrolytic salts has changed the composition of the electrolyte inside the battery, forming a crystalline state. This not only fixes the active substances on the plates, but also provides channels for ion exchange and migration, creating a stable internal structure and thus extending the service life. Therefore, Lead-Crystal Battery possess a series of excellent characteristics such as resistance to high and low temperatures, long cycle life, deep discharge resistance, low self-discharge, good consistency, and environmental friendliness.

• Hermetically sealed maintenance-free operation (eliminates leakage concerns)
• Certified as non-hazardous materials
• Absence of cadmium and antimony constituents
• Hybrid characteristics combining GEL and AGM benefits

The applicable environments and scenarios of Lead-Crystal Batteries
Lead crystal batteries provide adaptable energy storage across sectors due to their robust performance and sustainable attributes:
- Telecommunications Infrastructure
  Critical communication networks utilize these batteries for extended backup in geographically isolated installations, ensuring continuous operation during grid failures.
- Railway Networks
  Vibration-resistant construction reliably powers signaling systems, control hubs, and emergency lighting, maintaining safety compliance under extreme operational stresses.
- Uninterruptible Power Supply (UPS)
  Mission-critical facilities (data centers, healthcare institutions) deploy these batteries for fail-safe backup, leveraging their full-depth discharge tolerance and thermal resilience.
- Off-Grid Renewable Systems
  Solar/wind installations utilize their deep-cycling capacity to store surplus generation for discharge during low-production periods, enabling standalone power delivery.
Environmental compliance includes unrestricted transport classification and 99% recyclability, minimizing ecological footprint.

What is the lifetime of Lead Crystal Batteries？
• Operational Longevity: Achieves up to 15-year service life under optimal conditions (25°C ambient), contingent upon discharge frequency, maintenance rigor, and environmental variables.
• Storage Performance: Ultra-low self-discharge (<3% monthly) permits storage exceeding 24 months without recharge, ideal for emergency standby applications.

Depth of Discharge (DOD) Capability?
Engineered to sustain 100% DOD cycling without accelerated degradation, outperforming conventional lead-acid chemistries in deep-cycle resilience. This capability ensures reliable power delivery for demanding applications.

Storage Capacity Characteristics
Energy storage capacity varies according to system requirements rather than physical constraints. Crucially, these batteries maintain charge integrity for over 24 months during storage due to minimal self-discharge (<3% monthly), ensuring immediate deployment readiness after extended dormancy.

Sulfation Resistance
Sulfation formation is exceptionally uncommon owing to proprietary electrolyte formulation with reduced sulfuric acid concentration and advanced plate architecture.
