AI-Powered supplier vetting

SummaryLINYI POWERSHIBA IMP AND EXP CO., LTD. is a China-based limited company in Shandong that trades and produces batteries, including dry, heavy-duty, alkaline, button-cell, lithium-ion rechargeable, and nickel-metal hydride rechargeable products. The evidence is inconsistent regarding establishment history, facility scale, staffing, certification, and production resources: one set of data reports a 2019 establishment, 26 employees, a 2,306 m² plant, two R&D engineers, and no management-system certification, while another company overview claims operations since 1993, a 30,000 m² workshop, over 1,000 workers, 50 R&D engineers, 56 QC members, ISO9001:2015 certification, and output exceeding 30 million batteries monthly. The supplier states that it supports OEM production, owns several brands, and exports 90% of sales, but no concrete customer cases or documented after-sales system are provided.

Supplier typeThe supplier is identified as a China-based limited company with combined business activities and a battery-focused manufacturing and export profile. Its stated products include dry and heavy-duty batteries, alkaline batteries, button cells, and rechargeable batteries, while its business scope covers electrical and consumer electronics.

R&D capabilityThe supplier describes battery development, advanced production lines, and processing technology, and claims product improvements such as longer lasting performance, improved leak-proofing, impact resistance, and heat resistance. R&D resources are inconsistent across records—two R&D engineers in one slice versus 50 in another—so innovation capability is supported in principle but its scale is not reliably established.

Production capacityThe supplier identifies itself as a battery factory with production and export operations, advanced production lines, a stated 2,306 m² manufacturing area, and one-month lead times in both peak and off-peak seasons. Another record claims a 30,000 m² workshop, over 1,000 workers, and production exceeding 30 million batteries per month; because these figures conflict with the smaller facility and 26-employee record, production capability is evidenced but its actual scale remains uncertain.

Customization capabilityThe supplier explicitly states that it can provide OEM services and operates its own brands, including Powershiba, 666, and Leao. This directly supports customization or private-label capability, although no details are provided on minimum order quantities, design support, tooling, or customization scope.
