Company Profile

What We Do
ZHICOOL designs and manufactures high-reliability replacement batteries for smartphones, with an expanding portfolio for related smart devices. We serve three B2B segments:

• Repair networks and service centers that require stable supply, predictable quality, and clear warranty terms.
• Wholesalers and distributors that need broad SKU coverage, strong documentation, and repeatable margins.
• Building private labels with end-to-end support from brand to delivery for OEM and ODM partners.

Track record: Our core team has more than 10 years of experience in cell selection, pack engineering, and high-throughput manufacturing. The brand was founded in 2020, began overseas expansion in 2023, and now has active channels in the United Kingdom, Turkey, Brazil, Malaysia, and Vietnam.

Flexible Lead Times You Can Plan Around

• Four automated production lines with annual capacity exceeding two million units, expandable in peak seasons.
• Lead times: samples in 3 to 5 days for mainstream SKUs; mass production typically 7 to 10 days after confirmation, depending on volume and SKU mix.

Outcome: Fewer stock-outs, smoother rollouts, and better cash-flow planning for partners.

Premium Quality That Reduces Rework

• Three-stage inspection: IQC, IPQC, and OQC with SPC monitoring.
• First-pass yield of 99.6 percent; defect rate less than or equal to 0.4 percent tracked by batch.
• Tight internal resistance windows and true-capacity cell selection minimize early-life returns.
• Traceability: QR or serial, one pack, one ID. Batch analytics drive continuous improvement and faster RMA decisions.

Outcome: Faster bench work, fewer comeback jobs, better store reviews, and less friction between sales and after-sales.

Clear Shipment Instructions

• CE, RoHS, FCC, CCC, UN38.3, and MSDS file sets available.
• UN38.3 transport compliance with standardized packing and labeling for air and sea.
• Country-specific templates for the European Union, the United Kingdom, and Southeast Asia, plus platform-audit-ready documentation.
• Coordination with your forwarders; clear packing lists and bill of lading elements to meet destination norms.

Outcome: Confident shipping, quicker customs clearance, and easier onboarding with chains and marketplaces.

Warranty and RMA You Can Trust

• Warranty up to 14 months, configurable by market and channel.
• Target defect returns less than or equal to 0.4 percent with a fast-track DOA process.
• Eight-discipline and corrective and preventive action methods for any batch-level anomalies; photo and video pre-screening to reduce unnecessary logistics.

Outcome: Predictable resolution times, data-driven answers rather than disputes, and satisfied downstream clients.

OEM and ODM That Launch, Not Linger

• A team of more than 20 specialists across market planning, brand and visual identity, packaging engineering, documentation, and quality assurance.
• End-to-end support: strategy, design, packaging, certification, and delivery.
• Anti-counterfeit features, serialization, multilingual kits, and retail or wholesale dual packaging options.

Outcome: A private label with distinctiveness and shelf discipline, shipped on time so you control the margin story.
