Shipping FAQ

At USA Batteries, we are committed to providing fast, free, and reliable shipping on every order. Below, youโ€™ll find detailed information about our shipping process, delivery timelines, carriers, and what to do if your order experiences an issue.


๐Ÿšš What is the cost of shipping?

Shipping is completely free on all orders โ€” no minimum purchase requirements, no hidden fees, and no surprise charges at checkout. We believe in transparent pricing so you can shop with confidence.


๐Ÿ“ฌ 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.


โฑ๏ธ How long does shipping take?

  • Standard USPS Delivery:ย Most items arrive withinย 3โ€“5 business daysย after leaving our warehouse.
  • Order Processing:ย Orders are typically processed and shipped withinย 24 business hoursย of purchase.
  • Delays:ย 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 weโ€™ll do our best to assist.


โšก 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 2โ€“3 business days for most U.S. locations.

If you need a faster delivery option, reach out to us at cs@usabatteries.com, and weโ€™ll check if a special arrangement can be made.


๐ŸŒŽ Do you ship internationally?

At this time, we only ship within the United States. We do not offer international delivery options.


๐Ÿ“ฎ Can you deliver to PO Boxes?

Yes! We gladly deliver to PO Boxes, as USPS handles most of our shipments.
If your order requires FedEx or UPS (usually for larger packages), we may contact you for a physical street address.


๐Ÿ” How can I track my order?

You will receive an email with a tracking number as soon as your order ships.
You can also check your order status anytime on our Track Your Order page.


๐Ÿ“ฆ Lost or Missing Packages

If your tracking number shows โ€œDeliveredโ€ but you havenโ€™t received your package:

  1. Check around your homeย โ€” porch, mailbox, garage, or any safe drop-off spots.
  2. Ask neighbors or household membersย in case someone accepted the package.
  3. Wait 24 hoursย โ€” USPS sometimes scans items as delivered before arrival.

If your package is still missing after these steps:

  • Contact yourย local USPS office. USPS can provideย GPS delivery confirmationย to determine where your package was left.
  • Contact us atย cs@usabatteries.comย or viaย Live Chat. We will assist you in opening an investigation and help retrieve GPS scan data if necessary.

Insurance Claims: All USPS shipments are insured. Any claims for lost or damaged packages must be filed with USPS. We will guide you through the process to ensure a resolution.


โœ… Our Commitment

Your satisfaction is our priority. If you experience any shipping issues, we will work closely with USPS or the relevant carrier to resolve the situation promptly and ensure your order reaches you safely.

The USABatteries.com Guarantee

Your satisfaction is our priority. Every battery from USABatteries.com is rigorously tested and backed by a comprehensive 1-Year Warranty. We are so confident in our quality that we offer a Risk-Free 30-Day Money-Back Guarantee: if you aren't completely happy within the first month, we will cover the return shipping costs ourselves. Quality power, zero risk.
