Sr626sw battery

The SR626SW is a Silver Oxide button cell commonly used in precision timepieces. You must verify a nominal voltage of 1.55V, a typical capacity of 26-28mAh, and dimensions of 6.8mm diameter by 2.6mm height. Ensure the battery is 'Low Drain' (W suffix), which is specifically designed for analog watches without high-power functions like backlights or alarms to ensure a leak-resistant long life cycle of 2-3 years.

To prevent damage to expensive movements, prioritize suppliers on Made-in-China.com that offer leak-proof technology and use high-purity silver oxide materials. Request discharge curve reports and verify that the internal resistance is stable. Authentic high-quality cells should have clean, burr-free stainless steel casings and clear laser-etched branding and date codes.

Compliance is critical for customs clearance. Ensure the products have UN38.3 test reports for safe transport, MSDS (Material Safety Data Sheets), and comply with the RoHS Directive (Restriction of Hazardous Substances) to ensure they are mercury-free. For the European market, CE marking and compliance with the EU Battery Directive (2006/66/EC) are essential.

SR626SW batteries have a shelf life of 3 to 5 years if stored in a cool, dry environment. When purchasing in bulk, aim for a manufacturing date within the last 6 months. Bulk discounts on Made-in-China.com can reduce unit costs by 40-60% compared to retail, but you must balance volume with your 12-month sales forecast to avoid 'dead stock' as voltage naturally drops over years of storage.

Batteries are classified as Dangerous Goods (DG) under international maritime and air regulations. The primary risk is short-circuiting during transit; therefore, batteries must be packed in blister cards or insulated trays rather than loose in bags. Ensure your freight forwarder is experienced in Class 9 Dangerous Goods handling to avoid shipment seizures or heavy fines at customs.

Always use Secured Trading Services provided by the platform to protect your payment. Negotiate a 30% deposit and 70% balance payment after a successful pre-shipment inspection (PSI). Explicitly define the defect rate tolerance (usually <0.5%) in the contract and require the supplier to provide a Certificate of Analysis (COA) for every batch.

For orders under 100kg, specialized DG couriers (like FedEx or UPS DG service) are fastest but expensive. For larger B2B volumes, LCL (Less than Container Load) sea freight is the most cost-effective. Ensure the outer cartons are UN-certified packaging and labeled with the correct Lithium/Battery handling labels to comply with international trade policies.
