How to Document a Claim for Defective Batteries

Preparing a Defective Battery Claim

If you believe batteries are defective, gather information that links the reported problem to the product and purchase. Include the product name, order reference, number of affected units, when the issue appeared, and a clear description of what you observed. Photos, along with any available inspection or test results, may help explain the concern.

These are practical records to share with the supplier, not documents that Vinnic’s available information identifies as mandatory. It also does not set out a compensation policy, warranty terms, claim deadline, or a specific remedy.

Evidence and Information to Gather

• Purchase and product details: Provide the product name, order reference, and quantity affected.
• Description of the issue: Explain what happened and when you noticed it, using factual language.
• Supporting documentation: Attach clear photos and any test or inspection findings you have. No required format is stated in the supplied information.
• Affected items: Keep the batteries and packaging available while you ask the supplier how to proceed. The published information does not specify return, handling, or disposal instructions.
• Request for next steps: Ask the supplier to confirm the applicable claim process and any available resolution.

Product and Quality Information

The listed product is a Vinnic 0% Mercury Silver Oxide Button Cell. Its stated characteristics include high leakage resistance, a constant voltage level, low self-discharge, and long running time. If your concern relates to one of these features, describe the battery’s observed behavior and the conditions in which it was assessed. Avoid presenting an unverified cause as established fact.

Chung Pak describes its quality checks as including full production-line inspection, laboratory sampling and testing, and incoming raw-material inspection. These details can provide context for a technical question, but they do not confirm the inspection outcome for any particular battery or batch. The company lists ISO 9001:2015 and IATF 16949:2016 certifications; batch-specific test records are not included in the available information.

Silver oxide button cells are listed for use in quartz watches, blood glucose meters, digital thermometers, calculators, precision sensors, and camera light meters. Mentioning the device and how the battery was used may help the supplier assess the report. No product-specific compensation formula or claim time limit is stated.

What the Available Information Says

Frequently Asked Questions

Can I make a claim using photos alone?

The available information does not define what evidence is acceptable. Photos can show visible conditions, but check with the supplier to learn whether test results or other records are also needed.

Does the published information promise compensation?

No. It describes after-sales support for feedback and after-sales issues, but does not state compensation guarantees, warranty coverage, or criteria for a remedy.

Should I return or dispose of the batteries?

Keep the affected batteries and packaging available until you receive instructions. The supplied information does not specify return, handling, or disposal procedures.

Recommended Next Steps

Send a concise, factual report that identifies the product and order, states how many batteries are affected, describes the issue, and includes any photos or test findings available. Ask the supplier to confirm the claim procedure and potential resolution before assuming that particular documents or remedies apply.

Chung Pak lists production-line inspection, laboratory sampling and testing, and incoming raw-material inspection as part of its quality process.
