FAQ

Frequently Asked Questions

Common questions about Zenilove lithium batteries, custom services, and ordering.

What types of lithium batteries does Zenilove offer?

Zenilove manufactures three main types of lithium batteries: Cylindrical Batteries (including 18650 and 21700 formats), Polymer Batteries (custom shape and capacity), and Button Batteries (including CR2032 and CR2025 coin cell formats). All three types are available as standard products or in custom configurations.

Do you support custom battery specifications?

Yes. Zenilove provides three custom cooperation models: OEM (you provide the design, we manufacture), ODM (we design and manufacture based on your requirements), and JDM (joint design and development between your team and ours). Contact us with your requirements to discuss the best approach for your project.

What is the difference between OEM, ODM, and JDM?

OEM — You provide finalized specifications and drawings; we manufacture to your design. Best for teams with in-house engineering.

ODM — You provide application requirements; we handle design and production. Best for teams who need a complete solution without internal R&D.

JDM — Your engineers and ours co-design together, combining your application knowledge with our battery expertise. Best for highly differentiated products.

What is the minimum order quantity (MOQ)?

The minimum order quantity starts from 3,000 pieces. Specific order details may vary depending on the battery type, specifications, packaging requirements, and custom needs. Please contact our team with your project details for an accurate quotation and order terms.

What certifications do your batteries support?

Zenilove batteries can be supported with the following international certifications for safe global shipment: UN38.3, MSDS, Sea Transport, and Air Transport. These cover international safety and transport compliance requirements for lithium batteries shipped by sea or air.

Which industries do your batteries serve?

Zenilove batteries are used across a wide range of industries including Industrial Equipment, Electric Vehicles & Mobility, Renewable Energy & Storage, Consumer Electronics, Medical & Healthcare, and Logistics & Robotics.
