    This does exactly what you would expect from a rechargeable battery, and at a good price point. Pros: - High current rating - Lasts a long time (2,4 Ah is probably correct in practical applications, others are often lower). - Correct size (dimensions given are correct) Cons: - None yet...

    I've used it/them now for over a year. I use the flashligt at work occasionally. Others have flashlights with ordinary not rechargable batterys and end up changing them 3 in time for when mine comes to the point that it needs a recharge. Bought 3 batterys, one recharger and two flashlights and to... Read more

    The product is working The batteries don't look to be made with high quality material The quality of material is ok, but could be better to be more confident, it looks that will get bad if stay in a humid place or do not take to much care of it. I didn't have time to to a lot of tests and see the... Read more

    These batteries are cheap enough that you can keep a few around in the charger waiting for use. This battery charges quickly. 2400mAh is NOT the highest capacity for this type of battery, but the price is right. This is not a "protected" battery - so if you use it in high-current situations such... Read more

    They are cheap. Also the effective time of working is good. I'm satisfied and I'll buy them again :). Also They come fully charged Cons: Those are NOT Batteries but Rechargeable Cells (). Inscriptions on the Cell are: "TR18650 2400mAh 3.7V" and "WARNING.The voltage of full charge (... Read more

    You can't beat the price! These cells can be used in a thousand ways. I have a small jack-of-all-trades type business and can use them to rebuild laptop batteries, power lighting mods for bicycles (great with a custom enclosure for cold cathode lighting effects, LEDs, etc.) The capacity is a this...

    Low-cost. They're 18650 cells. Other places sell these for over $10 each. Can also be used to re-cell laptop batteries. They last just as long as my name-brand cells. I use them in my Spyder II 300mW Green laser. After fully charged, some read at 4.2V, which is still within tolerance. The DX can... Read more

    Great batteries. Use them all the time on my flashlights that I bought here! They're not protected. Great batteries for the price. They can also be used as laptop cell replacement (like ACER). Another great bargain from DX!
