Dear friends, please note that for 18650 batteries, there will be differences in the printing codes of each batch of batteries produced, or some may not have printing codes, so the products sent out may not necessarily have the same color and logo as the first picture, and may also have other colors or even color differences. Wait, but what our merchant guarantees is that the model: It is definitely a 18650 battery, the capacity and quality are 100% Will not change!

​

Since the battery is small in profit but quick in sales, the buyer is responsible for the return shipping fee after the sale. If you take the photo, this rule will be accepted. Thank you. After receiving it, please test it and then spot weld it if there is no problem. It will not affect the second sale. If there is any problem, it can be returned or exchanged within 7 days.! Once the spot welding process affects the second sale, there is no warranty and no warranty. It cannot be returned or exchanged.!!!
