Allgrand

 

    In the fields of power guarantee and new energy energy storage, any power outage may lead to immeasurable losses and risks. With nearly four decades of dedicated development in the lead-acid battery industry, Allgrand Group relies on five core strengths including gel sealing technology, profound technical expertise, intelligent manufacturing capabilities, practical application verification and full-value-chain support, to deliver reliable backup power protection for data centers, communication base stations and all types of critical loads.

    In the safety management and control of lead-acid batteries, electrolyte leakage and thermal runaway have always been high-risk issues. Allgrand Group took the lead in introducing German gel battery processes, independently developed core technologies and realized their industrialized application. Our gel batteries adopt the composite combination of AGM technology and gel electrolyte, fundamentally eliminating potential safety hazards such as electrolyte leakage, electrolyte stratification and excessive water loss. The water loss rate is only half that of conventional lead-acid batteries, with a monthly self-discharge rate no higher than 3%. The batteries can serve as long-term backup power in both southern and northern regions.

    Safety stems from long-term technological accumulation and systematic quality assurance. Founded in 1987, Allgrand Group boasts a technical team led by German experts and has carried out in-depth industry-university-research cooperation with renowned universities including Technische Universität Berlin and Harbin Institute of Technology. Our products have obtained a host of authoritative certifications such as ISO9001, ISO14001, ISO50001, EU CE certification and TEL certification, establishing a stringent quality management system covering all product categories.

    Solid technological accumulation and continuous innovation capabilities ensure every Allgrand battery takes the lead from the very beginning of its development.

Robust Intelligent Manufacturing

    In data centers and critical backup power scenarios, manufacturing dispersion among individual battery cells will drag down the overall performance of the entire battery pack due to the bottleneck effect, resulting in a reduction in backup duration.

    Relying on full-process intelligent production management and control, Aoguan Group adopts the MES system for real-time recording and closed-loop control of key processes including lead powder preparation, plate pasting, colloidal electrolyte filling and internal formation. Before delivery, every single battery undergoes precise grouping based on voltage, internal resistance and capacity parameters. The internal resistance deviation is controlled within ±3%, and the capacity tolerance is no more than 2%. This fundamentally avoids overcharging or overdischarging caused by parameter dispersion of individual cells, ensuring stable backup duration for the entire battery pack and balanced power output throughout the full life cycle.

    From round-the-clock uninterrupted power protection for provincial government cloud centers in northern China, to the year-round stable operation of super-large internet data centers in southern China; from seamless power switching without service interruption in financial disaster recovery computer rooms amid regional power outages, to the reliable performance of telecom operator core nodes under severe thunderstorms during rainy seasons. Allgrand Group has demonstrated the reliability and long-term effectiveness of its safety guarantees through benchmark projects featuring stable operation across diverse application scenarios over extended service cycles.

    The reliability of energy storage and backup power systems depends not only on the technical quality of batteries themselves, but more importantly on whether full-lifecycle operation and maintenance support is properly in place. Allgrand Group has established a comprehensive service system covering pre-sales solution customization, installation and delivery, as well as after-sales remote diagnosis and on-site support. We have a team of professional technical engineers and a nationwide service network covering all provinces, municipalities directly under the Central Government and autonomous regions. Overseas warehouses have also been set up globally. Standardized processes are adopted to control delivery cycles, with a maximum warranty period of 5 years, ensuring the battery system maintains optimal performance throughout its entire lifecycle.

    As the core backup safeguard against power outages in data centers, Allgrand Group has established a five-dimensional security protection system:

Original colloidal sealed water-control technology paired with German precision engineering boosts product reliability.

Rigorous full-line quality control throughout intelligent manufacturing, backed by multiple authoritative certifications.

A full-lifecycle service network delivers real-time support.

Proven over years of deployment in benchmark projects.

This creates a fully closed-loop system spanning R&D, operation & maintenance, and after-sales service.

    Whether facing grid fluctuations or sudden power outages, Allgrand Group delivers stable power supply. With robust technical strength, it serves as a reliable backup power safeguard for the digital industry.
