We provide a 12 month warranty for manufacturing faults/defects. This warranty does not include negligence or misuse of batteries. This warranty does not include disposal due to accidental immersion of the battery into any water body (lake, stream, pond, or ocean), exposure to rain, overcurrent during battery charging or discharging, abuse, neglect, improper use, unauthorized modification or tampering, improper maintenance, unauthorized disassembly, fire, freezing, theft, accidental damage, or other forms of physical damage. All products undergo quality inspection before shipment. If you have purchased any product that seems to be problematic, please contact us.
In most cases, we can solve the problem by providing technical support without returning anything. We also guarantee that all other free products we sell (inverters, converters, chargers, etc.) will be defect free for 30 days
