2 Packs 18650 Rechargeable Battery 3.7V 3500mAh 18650 Button Top Battery for Headlights etc

My batteries came on time and I soldered them into my bluetooth speaker.Took a few hours for a full charge. Now the capacity is almost 24 hours at 1/3 volume . Up from 8-10 with original batteries.The original batteries were generic with the blue wrap just like these and they lasted 5 years.I had bought these other ones with the green label claiming really high amp hours, and they petered out after a few months , and had actually less capacity than the original batteries.Don't buy those , green label called SKY something or other, total crap .So far so good , and I would definitely go with any of the generic batteries with the blue wrap over most of the others with flashy names and unrealistic claims .

Great batteries IMO. I purchased for my vape and I use my vape all throughout the day/night at high wattage as well. They lasted 2 entire days before they began losing their charge. I knew they were going to be good once I charged them for the first time and realized how long they took to reach full charge. If your on the fence about purchasing, buy them. A lot cheaper than purchasing from a vape shop and they worked perfectly for me. Have never purchased a pair of batteries that have ever lasted as long as these do. Will buy again

perfect for my radiomaster pocket 🙃

I use them with my coin microscopeHaven't put them through a good test yet,to see how long they last .Seemed like a good value

Not much to say about batteries. The construction is clean and they arrived in a nice protection storage case. These are destined for a robotic toy and have a good Mhr capacity. Won't be able to tell how long they will last as this could take several years to find out.

I got this because one of my solar lights was not working. The battery came with charge and my light works now!

Just like apparently every 18650 battery sold on Amazon these are falsely advertised as being a different capacity than they actually are. Many other vendors will advertise capacities that are not possible like 9900mAh, but these appeared to be real as they advertised 3500mAh which is pretty much the max you can get out of 18650s other than some really expensive newer ones that go up to 3600mAh. When tested, these came in well short of the advertised capacity. One tested at 2136mAh and the other tested at 1782mAh. Combined that is barely over what one of them was advertised to be. They don't last long and don't hold a charge. Don't waste your time buying these or any other 18650 batteries on Amazon. Do yourself a favor and go buy them at a hobby shop or vape shop where they have real ones at the advertised capacity.

can not go wrong with price or quality
