Wholesale craftsman battery manufacturers

Buyers must prioritize Lithium-ion (Li-ion) chemistry for modern cordless tools to ensure high energy density and no memory effect. Key specs include Voltage compatibility (typically 19.2V C3 or V20 series) and Amp-hour (Ah) ratings, which determine runtime. Ensure the battery cells are sourced from reputable Tier-1 manufacturers like Samsung, LG, or Panasonic to guarantee stable discharge rates and a lifespan of 500+ charge cycles.

Batteries are classified as dangerous goods, so compliance is non-negotiable. Ensure the supplier provides UN38.3 test reports for safe transport and MSDS (Material Safety Data Sheets). For the US market, look for UL 2595 or UL 1642 certifications, and for Europe, ensure CE, RoHS, and WEEE compliance. These certifications confirm the battery has over-charge, over-discharge, and short-circuit protection.

When sourcing wholesale 'compatible' batteries, check the housing material (ABS+PC fireproof plastic) and the fitment precision of the locking mechanism. High-quality compatibles should feature an integrated LED fuel gauge and a BMS (Battery Management System) that communicates effectively with original Craftsman chargers to prevent overheating during rapid charging.

For B2B buyers, a mix of 2.0Ah (compact/lightweight) and 5.0Ah-6.0Ah (high-capacity/extended run) units is ideal. While 2.0Ah units have a lower unit cost, high-capacity batteries offer better margins and are preferred by professional contractors. Aim for a bulk discount of 20-40% compared to retail prices when ordering in quantities exceeding 100 units.

Batteries must be shipped according to IATA (Air) or IMDG (Sea) regulations. For wholesale quantities, Sea Freight (LCL/FCL) is the most cost-effective method, but requires Class 9 Dangerous Goods packaging. Ensure the supplier uses inner packaging that prevents short circuits and sturdy outer cartons with the correct UN specification markings.

Request a pre-shipment inspection (PSI) by a third party like SGS or Intertek. The inspector should perform a capacity discharge test on a random sample to verify if the actual Ah matches the label. Use Secure Payment services on Made-in-China.com to ensure funds are only released after the quality is verified and the bill of lading is provided.

Focus on warranty terms and RMA (Return Merchandise Authorization) policies. A professional supplier should offer at least a 12-month replacement warranty. Negotiate for a 1-2% spare parts allowance (extra units) to cover potential DOA (Dead on Arrival) cases, which is often more efficient than shipping individual faulty units back to the factory.

Check the HS Code (typically 8507.60) for your specific country to determine import duties. For US buyers, be aware of Section 301 tariffs on Chinese-origin goods. Ensure the Country of Origin (COO) is clearly marked on both the product and the packaging to avoid customs delays or seizures.
