ODM Battery Development Enquiries & Technical Brief | Longhehui

ODM battery enquiries: define the requirement first

Longhehui accepts ODM enquiries for mobile phone, tablet, laptop and smartwatch battery projects. This route is for buyers who need to discuss the battery specification and product requirements before a supply solution can be agreed. It differs from an OEM request based on an already defined specification.

Prepare a technical brief

Provide a drawing or existing battery label where available. Do not assume that batteries with similar names, shapes or advertised capacities are interchangeable. Compatibility and the scope of the project need technical confirmation.

How the project is reviewed

1. Send the technical brief and commercial requirements.
2. Review feasibility, unresolved specifications and the applicable documentation with our team.
3. Agree the proposed specification, quotation and sample plan.
4. Evaluate samples against the agreed requirements.
5. Confirm the final specification and order terms before production or supply.

Development work, tooling, testing, approvals, costs and timing depend on the project. They are not included automatically in a general product quotation. We confirm the agreed scope in writing rather than advertise a universal development timetable.

Capacity, energy and documentation

Keep rated capacity and typical capacity clearly distinguished. For a stated nominal voltage, energy in Wh equals voltage multiplied by capacity in Ah. An arithmetic match alone does not prove compatibility or performance. Request model-specific documentation and confirm the requirements of the destination market and carrier before ordering.

Purchasing and warranty

Our general purchasing policy is a minimum order of 5 pieces and paid sample purchases of 2 pieces. Confirm project-specific development and customization conditions in the quotation. The warranty period starts on the shipment date and ends after 1 year or 500 cycles, whichever comes first. Full claim terms are shown in our purchasing and warranty policy.

Send your project brief

Email longhehuibattery@gmail.com or contact Longhehui on WhatsApp. Include the device, battery reference if known, target specification, quantities and destination country. If the specification is already fixed and your main request is branding or packaging, ask about OEM supply.
