How to choose 18650 lithium battery suppliers and what pitfalls to avoid?

Product quality: This is the primary factor in choosing a lithium battery supplier. High quality lithium batteries should have characteristics such as high energy density, long cycle life, good safety and stability. Product quality can be evaluated by reviewing the supplier's product specifications, testing reports, and understanding their production process and quality control system. For example, Battsys Battery, as a leading manufacturer of rechargeable battery manufacturing technology in China, has advanced positive and negative electrode automated production lines. From battery design to material selection and processing, all aspects are strictly controlled to ensure reliable product quality.

Customization capability: Different application scenarios have different requirements for the voltage, capacity, size, shape, etc. of lithium batteries. Suppliers with customized service capabilities can better meet the special needs of customers. Battsys Battery can provide customized lithium battery solutions according to specific customer requirements.

After sales service: Good after-sales service is an important part of safeguarding customer rights and interests. Suppliers should provide timely and effective technical support and after-sales service, including product warranty, return and exchange policies, fault repairs, etc. Battsys Battery company adheres to the belief of "integrity-based, customer-centric", providing customers with comprehensive after-sales service to ensure that any problems encountered during use can be resolved in a timely manner.

Price performance ratio: Reasonable price is also an important consideration when choosing suppliers, while ensuring product quality and performance. It is necessary to comprehensively compare the prices, performance indicators, and service life of products from different suppliers in order to select the product with the highest cost-effectiveness. The company continuously optimizes production processes and management procedures to improve production efficiency and reduce costs, thereby providing customers with competitive prices.

Certification and Qualification: Legitimate lithium battery suppliers should have relevant certifications and qualifications, such as ISO9001 Quality Management System Certification, ISO14001 Environmental Management System Certification, UL Certification, CE Certification, etc. These certifications are a recognition of the supplier's product quality and production management level. The company is an ISO9001 and ISO14000 environmental quality management certified factory, a BSCI certified factory, and its products have passed CE, UL, RoHS, and REACH certifications, fully reflecting the high quality and safety of its products.

The pitfalls to avoid when choosing a lithium battery supplier
Capacity exaggeration: Some unscrupulous suppliers exaggerate the capacity of lithium batteries in pursuit of profit. For example, labeling a battery with an actual capacity of only 800mAh-1200mAh as 2000mAh for sale resulted in consumers discovering that the battery's endurance was far lower than expected after purchase.
Passing off inferior as good: selling low-quality battery cells or disassembled batteries as brand new batteries. The performance and lifespan of these batteries cannot be guaranteed, and there may even be safety hazards.
No return or exchange: Some battery cell manufacturers do not provide return or exchange services when selling products. Once customers purchase defective batteries, they can only bear the losses themselves, which increases procurement risks.
Exchanging concept: intentionally blurring key information in quotations or product descriptions to mislead customers. For example, quoting a 7.4V 10Ah battery as a 12V 10Ah battery, or using mWh instead of mAh to confuse the concept of battery capacity.
Trader trap: Some traders customize low-quality battery cells in order to reduce costs, and their cycle life is difficult to guarantee. Moreover, the unstable supply of goods from traders may affect the supply and quality of products.
