Do not mail, ship, or transport a swollen, hot, smoking, leaking, punctured, crushed, corroded, or physically damaged lithium battery unless you have received proper instructions from qualified personnel and the shipment is permitted under applicable regulations.
Stop using it
If a battery appears unsafe, stop using it immediately.
Move it to a safe spot
Move it away from flammable materials if it is safe to do so, place it in a fire-resistant or non-conductive area, and contact us for general guidance.
Contact local services if needed
Depending on the condition of the battery, you may also need to contact your local fire department non-emergency line or household hazardous waste facility.
QUESTIONS
Frequently asked questions
What is the fastest way to contact 18650BatteryStore.com?
The best option depends on your issue. Use the contact form or email support@18650batterystore.com for detailed technical questions, photos, order issues, or documentation. For simpler questions, you may call 1-800-547-3050 or text 1-833-419-2192.
Can you help me choose the correct battery before I order?
Yes. Please contact us before purchasing if you are unsure about cell size, top style, protected versus unprotected configuration, chemistry, voltage, discharge rating, charging requirements, or device compatibility. Battery sales are final, so we would rather help you confirm the correct product before checkout.
What details should I include for a battery compatibility question?
Include the device model, existing battery marking, required cell size, voltage, chemistry, top style, protected or unprotected requirement, discharge-current requirement, charger model, and any space limitations inside the device or battery tray.
What should I do if my package arrives damaged?
Contact us promptly with your order number and photos of the outside shipping box, shipping label, packing materials, and affected item. Keep the product and packaging until our team provides written instructions.
Can I return a battery if I ordered the wrong size or chemistry?
No. Battery sales are final. Lithium batteries and related electrical products are safety-sensitive, and once they leave our chain of custody we cannot verify their handling history, charge state, electrical condition, or use history. Please contact us before purchasing if you are unsure.
Can I ship a damaged, swollen, or leaking lithium battery back to you?
Do not ship a damaged, swollen, leaking, hot, smoking, punctured, or otherwise unsafe lithium battery unless our team has provided written instructions and the shipment is permitted under applicable transportation rules. Damaged lithium batteries can require special handling.
Do you support wholesale, commercial, or tax-exempt accounts?
Yes. Commercial customers, resellers, OEMs, battery pack builders, installers, and procurement teams can apply for a wholesale account. Include your company name, website, business type, expected monthly volume, target brands or sizes, and resale-certificate status.
Can I visit the Stockbridge, Georgia location?
Please contact us before visiting. Our address is listed for business and shipping correspondence, but retail pickup, in-person support, and warehouse access may be limited or unavailable depending on operations and safety requirements.
