Terms of service

Last updated: September 25, 2026

These Terms govern your use of scigoldpower.com (the "Site") and your purchase of products from SCIGOLD (operated by Scigold Technology Co., Ltd.). By using the Site or placing an order, you agree to these Terms. If you do not agree, please do not use the Site.

1. Eligibility

You must be at least 18 years old (or the legal age of majority in your jurisdiction) to place an order. By placing an order, you represent that you meet this requirement and that all information you provide is accurate.

2. Orders & Pricing

All prices are listed in US Dollars (USD) unless otherwise stated.
Prices are subject to change without notice; the price at checkout is final.
An order is not accepted until you receive an order confirmation email. We reserve the right to refuse or cancel orders for any reason, including pricing errors, suspected fraud, or limited availability.
If we cancel an order after payment, a full refund will be issued within 5–10 business days.
Sales tax is added at checkout based on the destination address where required by law.

3. Shipping & Delivery

We currently ship within the United States only.
Free standard shipping on US orders of $35 or more. Orders under $35 ship for a flat $4.99 standard shipping fee.
Standard delivery time is 3–7 business days within the contiguous US.
The BK5300 jump starter and power bank (115.2 Wh) ships by ground to the 48 contiguous states only, not to Alaska, Hawaii, Puerto Rico, US territories or APO/FPO/DPO addresses. See our Shipping Policy.
Title and risk of loss pass to you upon delivery to the carrier. We are not responsible for delays caused by carriers, weather, or other factors beyond our control.

4. Returns & Refunds

We offer a 30-day return policy from the date of delivery. To be eligible for a refund:

Items must be in original condition, with all packaging, accessories, and components included.
Used batteries that have been cycled more than 5 times are non-returnable for safety and hygiene reasons (you may still file a warranty claim — see Section 5).
Return shipping costs are the buyer's responsibility unless the item arrived damaged or defective.

To start a return, email info@scigoldpower.com with your order number. We will issue a Return Merchandise Authorization (RMA) and a shipping address. Refunds are processed within 5–10 business days of receiving the returned item, to the original payment method. The BK5300 (115.2 Wh) cannot be returned by USPS or by air; we will tell you how to send it back by ground.

5. Warranty

Every SCIGOLD product carries a 12-month limited warranty from the date of purchase against defects in materials and workmanship. The warranty covers, by category:

Cells (AA, AAA, 18650 and 21700): cells that fail to retain at least 80% of rated capacity within the first 100 charge cycles.
Charging cases and chargers (CW505, CW508 and CW401): malfunctions such as display failure, port damage or charging circuit defects.
Cables: fraying or connector failure under normal use.
Wall chargers: port damage, or failure to power on or to charge under normal use.
Portable chargers, including the BK5300 jump starter and power bank and the lightstick battery: port damage, or failure to charge, to hold a charge or to deliver power under normal use.

The warranty does not cover:

Physical damage from drops, crushing, or punctures.
Water damage (unless the product is marketed as water-resistant).
Use with incompatible chargers or in applications outside the product's intended use.
Normal wear on cosmetic finishes after extended use.
Loss or theft.

To file a warranty claim, email info@scigoldpower.com with your order number, a description of the issue, and photos or video where applicable. Warranty claims are typically resolved within 7 business days.

6. Product Use & Safety

SCIGOLD batteries contain lithium-ion chemistry and must be used responsibly. By purchasing, you agree to:

Use only with chargers and devices designed for the rated voltage and chemistry.
Not expose cells to temperatures above 60°C (140°F) or below -20°C (-4°F) for extended periods (the Cold-Weather 18650 series is rated to -40°C / -40°F).
Not puncture, crush, disassemble, or modify cells in any way.
Recycle exhausted cells responsibly through certified e-waste channels (Best Buy, Home Depot, Call2Recycle in the US).
Keep cells away from children and pets.

Full safety information is included with every order and at our safety guide.

We may update these Terms occasionally. Material changes will be posted with a new "Last updated" date and, where required by law, emailed to active customers. Your continued use of the Site after changes constitutes acceptance of the revised Terms.
