Warranty & Returns

Return Policy

Before initiating a return, please contact us to confirm return details. We usually process refunds within 1-3 business days after receiving returned goods, and funds typically arrive within 7 business days.
Whether return shipping is borne by the buyer depends on the following:

1. Buyer-caused return (e.g. no longer needed, wrong purchase): outbound and return shipping costs will be deducted from the refund, totaling approximately 25% of the product price.
2. Seller-caused return (e.g. battery quality issue, misleading product information): we bear all costs.

1-Year Warranty Service

All batteries purchased from this site include a one-year warranty. Within one year from purchase, if your battery fails under normal use, we provide replacement instead of repair to save your time.
The following are not covered:

1. Damage caused by misuse, overcharging, improper installation, freezing, or improper adjustment.
2. Battery disassembled or sticker removed.
3. Cannot be used due to system upgrade.
4. Note: After one year, remaining capacity around 80% is considered normal.

30-Day Returns

You may request a return within 30 days of purchase without giving a reason. Please contact us before returning an item. For buyer-caused returns, outbound and return shipping costs are deducted from the refund under our return policy; for seller-caused returns, we cover these costs.
