Lr41 button cell manufacturers

Buyers must ensure the nominal voltage is 1.5V and the chemistry is Alkaline (MnO2). The standard dimensions should be 7.9mm in diameter and 3.6mm in height. It is critical to verify the discharge capacity (typically 25-35mAh) and the leak-proof design, as low-quality cells can damage electronic devices through electrolyte leakage.

For global trade, products must adhere to IEC 60086 standards for primary batteries. For the EU market, CE marking and RoHS/REACH compliance (ensuring no mercury or cadmium) are essential. For the US market, compliance with the Mercury-Containing and Rechargeable Battery Management Act is required. Always request UN38.3 test reports and MSDS (Material Safety Data Sheets) for shipping safety.

A high-quality LR41 cell should have a shelf life of at least 2 to 3 years when stored at room temperature. You should ask suppliers for discharge curve reports and accelerated aging test results. Ensure the internal resistance remains low over time to prevent sudden voltage drops in high-precision devices like digital thermometers or laser pointers.

If sourcing for retail, blister card packaging (5pcs or 10pcs) with barcodes is standard. For industrial assembly (e.g., toy manufacturing), bulk tray packaging is more cost-effective. Ensure the packaging includes child-safety warnings, as small button cells pose a significant ingestion risk.

Batteries are classified as Dangerous Goods (Class 9) in some jurisdictions, though alkaline button cells are often exempt under specific conditions. You must ensure the supplier provides a Certificate for Safe Transport of Chemical Goods. Failure to provide correct documentation can lead to customs seizures or airline rejections.

Implement a Pre-Shipment Inspection (PSI) protocol where a third party tests the Open Circuit Voltage (OCV) and Closed Circuit Voltage (CCV) of a random sample. On Made-in-China.com, prioritize Audited Suppliers who offer Trade Resources or inspection services to guarantee that the production date is within the last 3 months.

Focus on the price-to-weight ratio and volume tiers. For orders exceeding 100,000 units, aim for a 15-20% discount off the standard wholesale price. Negotiate for OEM branding (private labeling) which is often included for free at high volumes, and insist on payment terms like 30/70 (T/T) where the balance is paid only after a successful QC report.

Check the HS Code (typically 8506.10) for your specific country to determine tariff rates. Be aware of Extended Producer Responsibility (EPR) laws in regions like the EU, which may require you to register for battery recycling schemes and pay environmental fees based on the tonnage imported.
