Lr20 d alkaline battery

When sourcing Lr20 (D size) batteries, you must prioritize nominal voltage (1.5V) and discharge capacity, which typically ranges from 12,000mAh to 18,000mAh depending on the load. Ensure the battery uses high-purity manganese dioxide and zinc powder to prevent internal resistance buildup. For industrial or high-drain applications, verify the leak-proof structure and the use of a stainless steel jacket to prevent corrosion and ensure structural integrity over a long shelf life, which should ideally be 5 to 10 years.

Compliance is critical for legal entry into global markets. Ensure the products meet IEC 60086-1 and 60086-2 standards for primary batteries. For the US market, mercury-free certification and compliance with the Mercury-Containing and Rechargeable Battery Management Act are required. For the EU, batteries must adhere to the Battery Directive (2006/66/EC) and REACH regulations. Additionally, a valid MSDS (Material Safety Data Sheet) and UN38.3 test report are essential for international logistics and safety verification.

Request a discharge curve report under different resistance loads (e.g., 2.2 ohm or 3.9 ohm) to verify the service life hours. Professional suppliers should provide on-site audit reports or third-party inspections from agencies like SGS or Intertek. Look for manufacturers with ISO 9001 (Quality Management) and ISO 14001 (Environmental Management) certifications. It is highly recommended to use Made-in-China.com to find 'Audited Suppliers' who have undergone rigorous background and production capability checks.

Lr20 batteries are designed for high-drain and continuous-use devices such as gas water heaters, large flashlights, radio receivers, and motorized toys. In industrial contexts, they are used in automatic valves and safety equipment. The functional requirement is a stable voltage output even in extreme temperatures (typically -20°C to +50°C). For B2B buyers, ensuring the battery has a low self-discharge rate is vital for products that may sit in inventory or emergency kits for extended periods.

The primary risks include leakage during transit due to poor sealing and capacity fraud, where the actual mAh is lower than advertised. To mitigate this, always request pre-shipment samples and utilize Trade Assurance services on platforms like Made-in-China.com to protect your payment until the goods are verified. Another risk is customs seizure if the packaging lacks the required hazardous material warnings or correct HS Codes (typically 8506.10).

Focus negotiations on price-to-weight ratios and mercury-free guarantees. For orders exceeding 50,000 units, you can typically negotiate a 10-15% discount. Discuss OEM/Private Labeling costs early, as custom printing on the battery jacket usually requires a higher MOQ (Minimum Order Quantity). Demand a guaranteed shelf-life clause in the contract, ensuring that the batteries delivered have been manufactured within the last 3 months.

While alkaline batteries are not classified as 'Dangerous Goods' as strictly as Lithium batteries, they are still subject to special provisions (e.g., IMDG Code SP 304). They must be insulated to prevent short circuits during transport. For sea freight, ensure the supplier uses moisture-proof pallet packaging. If shipping to the US or Europe, confirm the supplier is familiar with FBA (Fulfillment by Amazon) labeling requirements if applicable, or specific national port safety regulations.

Always conduct transactions through secure payment gateways provided by reputable B2B platforms. Avoid direct wire transfers to private accounts. Use Escrow services where the funds are only released after you provide a clean Inspection Certificate. For large-scale procurement, hiring a third-party inspector to visit the factory during the production mid-phase and final loading is the most effective way to ensure the physical quantity and quality match the proforma invoice.
