AI-Powered supplier vetting

SummaryShenzhen Eastar Battery Co., Ltd. is a China-based limited company established in 2006 and located in Shenzhen. It operates in battery and energy-storage products, with stated production capacity above 10 lines and annual battery productivity of 500,000 pieces. The supplier reports exports to Africa, Southeast Asia/Mideast, and North America, with export sales representing 71%–90% of total sales. It states quality-control procedures, battery testing before delivery, after-sales support, and OEM/ODM experience. CE, CB, IEC, BIS, and UN38 are referenced, while supplier management-system certification is listed as NIL. Evidence is insufficient to verify financial strength, specific customer cases, or the extent of customization beyond general OEM/ODM claims.

Supplier typeThe supplier is identified as a limited company and trade company in Shenzhen, China, engaged in electrical and electronics and consumer electronics, with battery products as its stated focus. The available information also describes manufacturing operations, but the trade-company classification remains explicit.

CertificationsThe supplier references CE, CB, IEC, BIS, and UN38 certifications and states that it owns ISO, CE, and CB; however, supplier management-system certification is recorded as NIL. The evidence supports product or compliance certifications but does not establish the scope or validity of each certification.

After-Sales capabilityThe supplier explicitly claims a robust after-sales service system and 24-hour professional online service for technical problems. These are stated capabilities, although no service-level metrics, support locations, or case evidence are provided.

Production capacityThe supplier reports more than 10 production lines, annual battery productivity of 500,000 pieces, lead times within 15 working days in both off-peak and peak seasons, and quality controls from IPQC through OQC with testing before delivery. These stated capacity, delivery, and quality processes support a positive production assessment, although the reported total employee count and manufacturing-area details are not reconciled with the production claims.

Customization capabilityThe supplier states more than 20 years of OEM and ODM experience and offers multiple battery and energy-storage products. A specific NCM 21700 rechargeable battery specification is also shown, but there is no detailed evidence on customization scope, minimum orders, engineering support, or tooling.
