Terms & Conditions<\/a>. Nothing in this policy limits any statutory right that cannot be excluded by law.<\/p>\n2. Inspection Window<\/h2>\n
Please inspect your shipment on arrival. If goods are defective, damaged, or differ from the specification confirmed on the proforma invoice, contact us in writing within 7 calendar days<\/strong> of delivery. Claims received after this window cannot normally be accepted, because we can no longer establish whether the issue arose in transit, in storage or in use.<\/p>\n3. When We Accept a Return or Claim<\/h2>\n\n- The item is not what was ordered \u2014 wrong model, capacity, voltage or connector.<\/li>\n
- The item is dead on arrival, or its measured capacity or internal resistance falls outside the tolerance stated in the datasheet.<\/li>\n
- The item was damaged in transit and the damage was noted and photographed at the time of delivery.<\/li>\n
- The item fails within the 12-month warranty period due to a manufacturing defect.<\/li>\n<\/ul>\n
4. When We Cannot Accept a Return or Claim<\/h2>\n\n- Custom and OEM\/ODM orders<\/strong> produced to your specification, including custom dimensions, tabs, connectors, BMS settings, labelling or branding.<\/li>\n
- Damage caused by over-charging, over-discharging, reverse charging, short circuit, or use outside the voltage, current and temperature limits in the datasheet.<\/li>\n
- Physical damage after delivery: crushed, punctured, swollen, water-damaged or burned cells.<\/li>\n
- Unauthorised disassembly, modification, spot-welding directly on the cell body, or repair by a third party.<\/li>\n
- Normal ageing \u2014 gradual capacity fade and increasing internal resistance over charge cycles.<\/li>\n
- Change of mind, over-ordering, or a project that was cancelled by the Buyer.<\/li>\n
- Storage in a humid, condensing or high-temperature environment, or beyond the storage period stated in the datasheet.<\/li>\n<\/ul>\n
5. A Note on Returning Lithium Batteries<\/h2>\n
Lithium cells and packs are regulated dangerous goods. Many couriers will not accept loose cells for return, and air transport is restricted. This means a physical return is often neither safe nor economic, particularly for small quantities.<\/p>\n
In most cases we therefore resolve approved claims by replacement or credit<\/strong> rather than a physical return. Where a return is required, we will advise on a compliant carrier. Please do not send batteries back before receiving a return authorisation from us \u2014 unauthorised shipments may be refused or destroyed by the carrier, and we cannot take responsibility for goods we did not agree to receive.<\/p>\n6. How to Make a Claim<\/h2>\n\n- \u0415\u043b\u0435\u043a\u0442\u0440\u043e\u043d\u043d\u0430 \u043f\u043e\u0448\u0442\u0430 mayliu@huanhuanpower.com<\/strong> within 7 calendar days of delivery.<\/li>\n
- Include: order or proforma invoice number, product model and quantity, batch code from the cell label, a description of the problem, and photographs or a short video showing the issue.<\/li>\n
- Include measurement data where relevant (capacity test, voltage, internal resistance) and the test conditions used.<\/li>\n
- We will acknowledge within 2 business days and complete our assessment within 7 business days. We may ask for additional tests or for samples to be returned for analysis.<\/li>\n
- If the claim is approved, we issue a return authorisation (RMA) number or a resolution directly.<\/li>\n<\/ol>\n
7. Remedies<\/h2>\n
For an approved claim we will, at our option: replace the affected items in the next production batch, issue a credit against a future order, or refund the invoiced value of the affected items. Where only part of a shipment is affected, the remedy applies to that part only.<\/p>\n
We do not compensate for consequential losses such as lost flight time, lost contracts, downtime or damage to third-party equipment.<\/p>\n
8. Refunds<\/h2>\n
Approved refunds are made within 7 business days<\/strong> of approval, using the original payment method. Bank charges, intermediary fees and currency conversion differences are not refundable.<\/p>\nWhere a refund relates to goods already delivered, we may deduct the outbound freight cost and any duties or taxes that we cannot recover.<\/p>\n
9. Who Pays Return Freight<\/h2>\n
If the claim is our responsibility \u2014 wrong item, manufacturing defect, damage caused before dispatch \u2014 we cover the cost of the compliant return and the replacement shipment.<\/p>\n
If the return is for any other reason accepted at our discretion, the Buyer bears the return freight, insurance and any duties.<\/p>\n
10. Warranty vs Returns<\/h2>\n
Returns deal with goods that are wrong or faulty on arrival. Warranty deals with manufacturing defects that appear during the 12-month warranty period. Both start with the same claim process described in section 6.<\/p>\n
