Battery arrives quickly, no issues that I can see
These batteries hold a charge well. I use these batteries often out in areas where dependability is a must... they have never failed. They were a great buy.
Many cheap 18650s out there are truly quite nasty. A year back, when I foolish, I bought some Ebay Ultrafire 18650s. For $1 per battery. Not only did they have horribly low capacity, there were also dangerous to use and charge. Especially when you are charging them with an Ebay charger.
These are totally different batteries altogether. They are the best bang for your buck you can get. They actually have a capacity of 2400mAh, and they all discharge the same so they can be used in series and parallel.
The protection circuit is great, it stops shorts and battery over/under charge.
These batteries are highly recommended.
