Three year warranty and warranty scope
1. All power supply products purchased from our company are guaranteed with the machine production serial number, and can enjoy a three-year warranty service from the date of purchase. (Battery models below 12V24AH are guaranteed for one year)
2. If there is a major quality accident with the product within one month of purchase, the product can be replaced with a new one if the packaging is complete, the packaging data is complete, the serial number is correct, and the product casing is not scratched. This ensures that your risk is zero.
3. If the following situations occur, they are not within the scope of warranty, but we also adhere to the concept of "full support" and negotiate with customers to resolve:
3.1 Damaged or lost product identification or serial number;
3.2 Damage or loss caused by weather conditions such as rain, humidity, lightning strikes, other natural disasters, or force majeure;
3.3 Violation of machine operation/usage regulations, resulting in deep discharge of batteries and other intentional damage;
3.4 Damage caused by unauthorized disassembly or attachment of other accessories, or malfunctions and damages caused by self transportation, movement, or negligence after installation.
Even if the product you purchased exceeds the warranty period, in order for you to still receive timely and convenient after-sales service, we are still willing to implement rapid maintenance, only charging cost fees, and providing on-site service.
