12PCS 18650 Rechargeable Battery 3.7 Volt Lithium 9900mAh Button Top Li-ion Batteries for Flashlights, Headlamps

First of all, the seller was great at responding back as soon as they could. Sometimes it was tricky due to time differences but regardless seller still answered every inquiry. My package got lost in the mail and the seller immediately offered a refund or re-shipment of the product. Seller was also kind enough to throw in some extra batteries for the inconvenience.Product works great! Haven’t had any issues at all, the batteries are great quality. Battery life is excellent and lasts forever! Will definitely be repurchasing in the future. Price point is pretty good too compared to other places I have purchased similar batteries at.

So far so good. These are getting hard to find, too many solar projects.

Able to use these for what I need and are very functional.

every battery can only charge to 1.5 volts and expensive charger reads them 100% charged. ive purchased dozens or this type of battery and they last close to 10 years. these didn't last a week.

I ordered a 12 pack and only received a 4 pack !

Battery keep there charge. Good choice to buy

On high they overheat & shut down or discharge in minutes in simple 1,000lumen headlamps. Have to set to low immediately. Other brands work fine.

I ordered a pack of 12 and the product got lost during shipment. Contacted the seller and it was resolved right away. I would recommend this product, it works well. The seller provided exceptional service.
