Warranty Policy

Twenty-four months on every product, thirty-six where the page says so, a capacity floor you can hold us to, and a claim process that runs on the QR code printed on every cell.

1. Coverage Summary

Product line	Warranty term	Capacity floor during term
Prismatic LFP cells (CE series)	24 months	≥80% of rated capacity per Datasheet aging table
Assembled packs and drop-in batteries	24 months standard, 36 where stated	≥80% of rated capacity
Chargers and accessories	12 months	—

Terms run from the carrier-recorded delivery date. The warranty covers the original purchaser; Section 10 covers transfers.

2. What the Warranty Covers

Defects in materials and workmanship under normal, in-specification use: internal cell faults, weld and busbar failures inside assembled packs, BMS failures in managed products, enclosure defects, and capacity falling through the floor in Section 3. Our remedy is repair, replacement or credit under Section 7, and replacements carry the remainder of the original term.

3. Capacity Warranty Explained

Every battery fades with use; the warranty draws the line between normal fade and a defect. The Datasheet for your batch includes the aging table: expected remaining capacity by cycle count at the reference test (0.5C discharge at 25°C from full charge to cutoff). A product whose measured capacity, tested that way, sits below 80% of rating while inside its warranted cycle count and term is a warranty case. A pack cycled far past the table, stored at high temperature for long periods, or discharged below cutoff repeatedly is aging as chemistry dictates, not failing.

4. What Is Not Covered

• Physical damage: drops, punctures, crushing, fire, water beyond the stated ingress rating.
• Charging below 0°C without heating or a low-temperature cutoff; over-voltage charging; lead-acid charger profiles including equalization.
• Installation faults: reversed polarity, undersized or unfused cabling, loose terminal hardware, missing BMS on bare-cell builds.
• Opening, modifying or repairing outside our written authorization.
• Normal capacity fade inside the Datasheet aging table, and cosmetic marks that do not affect function.
• Products with removed or defaced QR codes or serial labels, and products bought from unauthorized resellers.
• Consequential costs: removal, reinstallation, downtime, hired equipment, spoiled goods (see Section 11 for rights that survive this exclusion).

5. How to Make a Claim

1. Email sales@shinkopower.com with “Warranty claim” and your order number in the subject line.
2. Include the information in Section 6.
3. We acknowledge within one business day and usually give a first assessment within three, because the QR codes let us pull the exact batch test records your cells shipped against.
4. If a return is needed, we send a prepaid ground label or book freight; do not ship anything before the RMA arrives.

6. What We Need From You

• Order number or proof of purchase.
• The QR code or serial of each affected cell or pack (a phone photo is fine).
• A description of the fault and when it appeared.
• Any measurements you have: rest voltage, charger behavior, capacity test result, BMS app screenshots. None are mandatory, but each one shortens the assessment.
• Photos or video where the fault is visible.

7. Assessment and Remedies

Many claims resolve remotely from the data above. Where the product returns to us, inspection and the reference capacity test complete within 5 business days of arrival. Confirmed defects are remedied at our option by repair, replacement with the same or a better-spec product, or credit of the price paid. If we ever cannot supply an equivalent product, you receive a full refund for the defective unit. Remedies ship at our cost by the standard method.

8. Dead on Arrival

A product that fails our reference test out of the box, reported within 14 days of delivery, is handled as priority DOA: replacement dispatched as soon as the fault is confirmed, transport both ways on us, no restocking consideration of any kind.

9. Shipping Costs on Claims

Outcome	Inbound (to us)	Outbound (back to you)
Defect confirmed	We pay	We pay
No fault found, product in spec	You pay	You pay

Where no fault is found we send you the test data before anything ships back, so you can decide with the numbers in hand.

10. Transfer, Term and Renewal

The warranty is not transferable except with the sale of equipment in which the product is permanently installed, where the remaining term follows the equipment on written notice to us. The term is never extended by a claim, and replacements inherit the remaining term rather than starting a new one.

11. Your Legal Rights

This warranty is in addition to rights that consumer law gives you, and nothing here limits rights that cannot lawfully be limited. To the extent permitted by law, this document states the exclusive contractual warranty and remedy; some jurisdictions do not allow certain exclusions or limits on implied warranties, so parts may not apply to you. This warranty gives you specific legal rights, and you may have others that vary by state or country.
