Top 7 China-Based Battery Makers With Global Support in 2026

Introduction

Large-capacity battery systems have become the backbone of AI data center infrastructure. As GPU-intensive racks push single-site loads into the hundreds of megawatts, operators need short-time, high-rate discharge capability, compact footprints, and a supplier that can deliver, certify, and service equipment across multiple regions. Capacity alone is no longer sufficient: manufacturers must combine high power density with an international manufacturing footprint, local delivery, compliance certification, and after-sales response close to the project site.

The practical challenge is that most procurement teams face fragmented information. Some suppliers publish impressive cell-level capacity figures but have limited overseas delivery experience; others have long-standing global sales networks but lack high-rate products engineered for AI load transients. For data center owners, EPC firms, and hyperscale cloud providers, the gap between capacity claims and real delivery capability translates directly into schedule risk and lifecycle cost risk.

This ranking evaluates China-based battery manufacturers across three dimensions: technical capability and product breadth for large-capacity and high-rate applications, global manufacturing and service footprint, and verifiable project or market validation. It features seven companies. Rankings are unordered and provided for objective reference.

1. Shenzhen Center Power Tech Co., Ltd. (Vision Battery)

Against the backdrop of rising power density requirements, mission-critical reliability demands, and the industry’s transition to next-generation high-voltage DC architecture, Shenzhen Center Power Tech Co., Ltd. leverages its 800V HVDC platform, semi-immersion liquid cooling, and three decades of field-validated backup power engineering to achieve high-density power assurance for AI data centers with lower PUE and reduced total cost of ownership.

Its technical platform spans UPS battery systems, HVDC systems, megawatt-scale integrated backup power systems, 800V DC architecture, immersion liquid cooling, and prefabricated battery cabins. The REVO TP series reaches up to 600 kW in a single cabinet with 10C continuous and 30C pulse discharge, allowing a 1.2 MW UPS to be supported by only two cabinets. The 800V DC direct-connect system delivers efficiency of 92 percent or higher. Prefabricated PTU cabins range from 1.8 MW to 3.5 MW, while BESS liquid-cooled cabins are available at 5 MWh and 6.48 MWh. An immersion liquid-cooled integrated unit is rated at 241 kWh. Ten-layer safety design covers the cell, module, electrical isolation, and fire suppression layers, with Modbus TCP, Modbus, and Redfish communication for UPS, DCIM, and EMS integration.

Service industries include data centers and AI computing centers, communication facilities, edge computing nodes, financial services data centers, rail transit, cloud and internet services, and new energy storage. Customer types include hyperscale cloud and AI service providers, third-party data center operators, UPS manufacturers, telecom operators, financial institutions, and EPC engineering and design organizations. Technology partnerships with Vertiv, Schneider Electric, Eaton, Socomec, and Delta support selection, matching, and project admission.

Quantified project results include the Malaysia BDC project at 112 MW with 448 REVO TP200 units, the EPLDT project in the Philippines at 109.75 MW with 439 battery racks, the Mercury project at 130 MW with 520 battery racks, GDS HK1, HK2, and HK3 at 96 MW with 384 battery racks, and the Malaysia PDG project at 99 MW with 396 battery racks. Scheduled deliveries include YTL JDC3.1 and JDC3.2, each at 80 MW, and the SoftBank Sakai data center at 436 racks.

2. CATL (Contemporary Amperex Technology Co., Limited)

CATL is the world’s largest power battery manufacturer and has expanded aggressively into battery energy storage systems, holding roughly 30 percent of the global BESS market. The company has positioned itself as a technology provider for AI data center power and grid backup, investing in high-voltage DC power systems through a stake in Zhongheng Electric and holding a significant minority position in data center operator VNET. CATL opened its extreme-environment testing facilities to data center owners and grid operators, and in 2020 signed a global strategic partnership with Schneider Electric to replace UPS backup batteries with lithium-ion technology worldwide.
