Our Story

Naradex Battery Tech Co Ltd is a company engaged in the design, manufacture, sales and marketing of a wide range of valve regulated lead acid batteries, especially UPS/Telecom/Station backup AGM batteries and the development of customized battery solutions. Since established in 2015, we have developed step by step from a small factory to a mid-to-large size factory. Over 400 employees are dedicated exclusively to backup AGM battery production — nothing else, just batteries done right.

Not only have our production capacity expanded, but also our technology, quality and management systems have been continuously improved. We invested roughly one million USD in advanced machinery to improve our production efficiency and battery quality. These equipment include fully automatic ball mill machines, mixing & pasting machines, curing ovens and environmental facilities.

Today, we produce 400,000 KVAH of batteries annually and export to more than 100 countries, serving as a reliable battery partner for UPS system integrators, telecom operators, and power utility companies worldwide.

IQC — Incoming Quality Control

Raw material purity testing and cover withstand testing. Every batch of lead ingots, separators, ABS containers, and sulfuric acid is tested before entering production.

PQC — Production Quality Control

In-process inspection at every stage: welds checking, terminals checking, acid checking, voltage testing per cell, and finished product machine testing for capacity and internal resistance.

OQC — Outgoing Quality Control

Final battery performance testing, capacity verification, printing and surface checking. Zero-defect confirmation before any battery leaves the factory.

Premium Raw Materials

Quality starts with materials. Our AGM batteries use thick high-Sn low-Ca lead alloy grids with proprietary PAM additives for 30% more cyclic life. For OPzV gel batteries, we import AEROSIL 200 fumed silica gel powder from Evonik (Germany) — the world standard for premium gel electrolyte.

Packaging & Shipping

All batteries ship on non-fumigation wood pallets with stretch-wrap protection. MSDS certified for safe international shipping by sea and air. We support OEM retail packaging for distributors entering retail channels (e.g. Menards, hardware stores).
