MODEL OVERVIEW
LG 18650-HE4 — Selection & Sourcing
LG 18650-HE4 is a 18650 cylindrical lithium-ion cell. The supplied document lists 2500mAh nominal. Use the historical 2013 document as an engineering reference. Confirm the matching revision and lot before production approval.
For pack qualification, review the charge profile, continuous and peak load, mechanical clearances, protective circuitry and cell temperatures against the exact specification. A similar cylindrical format does not make different cell models interchangeable.
For a model-specific quotation, provide your sample and production quantities, delivery destination and required documentation. Source reference: BCY-PS-HE4-Rev0, 2013-05-30, pages 4–6.

APPLICATION REVIEW
What to Check for Your Pack
For these project types, compare usable energy at the working load, cell-holder tolerances, busbar design and the temperature-dependent operating limits.
- Energy and load: usable energy, continuous current, peak duration and charging opportunities.
- Mechanical and thermal fit: the exact drawing, connections, enclosure temperature and cooling arrangement.
- Qualification: a test plan based on the finished equipment, including its protection settings and required approvals.
PROCUREMENT DOCUMENTS
Datasheet, Traceability & Certificates
Ask for the specification and drawing that match the offered lot. If your project needs a UN 38.3 test summary, SDS or a particular cell certificate, include that requirement in the enquiry.
BUYER QUESTIONS
Before You Order
Is this cell suitable for my application?
For these project types, compare usable energy at the working load, cell-holder tolerances, busbar design and the temperature-dependent operating limits. Application names on this page are evaluation starting points, not a claim that an OEM has approved this exact cell.
Can I get the LG 18650-HE4 datasheet?
Yes—send the complete model code and your project requirements. We will review the matching specification and available documentation with you. Any preliminary values should be confirmed before production approval.
What are the wholesale price, MOQ and lead time?
These are quoted for the requested model, quantity, available lot and destination. Send sample demand and expected production volume so the offer can address your schedule.
Which documents should accompany the order?
Ask for the applicable specification revision, lot identification, SDS and UN 38.3 test summary, plus any model-specific certificates required for your market. Cell documents do not replace finished-pack or equipment approval.
Compare Other 18650 Series
Compare exact specifications; a similar format does not mean the cells are interchangeable.
