Frequently Asked Questions

Find answers to common questions about our products

Yes. All cells we sell are guaranteed authentic, Grade A, and brand new. Not reclaimed, used, or rewrapped. We also prioritize fresh manufacturing dates, so you’re not receiving cells that have been sitting around for years.

Some sellers offer Grade B cells that can have inconsistent voltage, higher internal resistance, reduced performance, or other issues. You will never receive a Grade B, reclaimed, or used cell from us.

These are sold as bare cells (no welded tabs or leads) unless the listing explicitly states otherwise.

To make pack building easier, our cells are sorted and batched for matching internal resistance, voltage, and date code, so they arrive ready to be assembled into a pack.

U.S. orders ship from Atlanta, Georgia.

For international orders outside the USA, we may ship from a different fulfillment hub depending on the product’s manufacturing location, to ensure faster and more efficient delivery.

Shipments within the USA, delivery in 1–3 days (up to 5). Expedited shipping available. International shipping varies—contact us to inquire.
