📬 Which shipping carriers do we use?
Most orders are shipped via USPS (United States Postal Service), which provides fast and affordable nationwide delivery. For large, heavy, or bulk orders, we may use FedEx or UPS to ensure safe and efficient handling.
Please Note: Some oversized products or wholesale shipments may require alternative carriers based on size, weight, or destination.

- Order Processing: Orders are typically processed and shipped within 24 business hours of purchase.
- Delays: Shipping times may be longer during weekends, public holidays, or severe weather conditions.
If your order is time-sensitive, please contact us before purchasing, and we’ll do our best to assist.
⚡ Do you offer expedited shipping?
Currently, we do not offer paid expedited shipping options. However, many of our USPS shipments use Priority Mail, which generally arrives within 2–3 business days for most U.S. locations.
If you need a faster delivery option, reach out to us at cs@usabatteries.com, and we’ll check if a special arrangement can be made.

If your tracking number shows “Delivered” but you haven’t received your package:
- Check around your home — porch, mailbox, garage, or any safe drop-off spots.
- Ask neighbors or household members in case someone accepted the package.
- Wait 24 hours — USPS sometimes scans items as delivered before arrival.
If your package is still missing after these steps:
- Contact your local USPS office. USPS can provide GPS delivery confirmation to determine where your package was left.
- Contact us at cs@usabatteries.com or via Live Chat. We will assist you in opening an investigation and help retrieve GPS scan data if necessary.
