Returns Policy

1. Return window

You have 7 calendar days from the date the carrier marks your package "Delivered" to request a return. We chose 7 days (rather than 30) because lithium batteries lose useful life with every cycle — a 30-day window would mean returning used product.

2. What you can return

• Any CEENR battery, charger, adapter, inverter, or bundle.
• The product must be in its original packaging with all included accessories.
• Up to 1 charge cycle is fine (we expect you to test it).
• Visible physical damage from misuse (drop, crush, water exposure) is not eligible.

3. What you cannot return

• Products purchased more than 7 days ago (use the 3-year warranty instead if there's a defect).
• Custom or special-order items.
• Items showing physical damage from misuse, drops, water, or use beyond rated specifications.

4. How to start a return

1. Email [email protected] with subject "Return request — Order #XXXX" within 7 days of delivery.
2. Include: your order number, the SKU(s) you want to return, and a one-line reason (helps us improve — not required for approval).
3. Within 1 business day, we reply with a prepaid UPS return label and packing instructions for lithium batteries (mandatory under 49 CFR § 173.185).
4. Pack the battery exactly as instructed (terminals taped, original box or equivalent, hazmat label affixed by you using the file we send) and drop off at any UPS location.
5. Once we receive the package, we inspect and refund within 5 business days.

5. Refunds

• Refunds go back to your original payment method.
• Original shipping charges (if any) are refunded with the product price.
• Refunds typically appear on your statement within 5–10 business days, depending on your bank.

6. Return shipping cost

Reason for return	Return shipping
Defective, wrong item shipped, damaged in transit	Free — we cover the label
Changed your mind, ordered wrong, no longer needed	$8.99 deducted from refund (covers hazmat shipping cost)

7. Exchanges

We do not process direct exchanges — it's faster to refund your return and place a new order. If you need help picking the right SKU, email [email protected] and we will recommend the right battery for your tools.

8. Damaged-in-transit claims

If your package arrives visibly damaged or the contents are damaged on unboxing:

1. Photograph the damage before discarding any packaging.
2. Email the photos to [email protected] within 48 hours of delivery.
3. We ship a replacement immediately and handle the carrier claim ourselves.

9. International returns

We currently ship only to US addresses. If you somehow received a CEENR product outside the US, contact us first — return shipping for lithium batteries internationally is highly regulated and may not be possible.
