Ultrafire 3.7V 18650 2400mAh Battery

Pros: best value 18650's i've seen build quality is good . long lasting performance .

Cons: not convinced on the 2400mah rating but would be closer to 2000mah. still higher than most

Other: hard to beat ,good run time for most torches

Pros: great battery for high output flashlights and other lights. alot cheaper than other 18650 cells and probably the same quality

Cons: is not 2400mah. i would say that it is around 2200mah but it is still worth the price. one of my batteries had a small lump near the bottom. i dont know if thats bad, but i assume it is

Other: not the full 2400mah rating but still good quality

Pros: These batteries last forever in my flashlight. I bought four but probably only needed two. I guess I better buy another flashlight!

Cons: I can't really think of any.

Other: The best battery I've ever used!

Pros: Fits all my flashlight Cheap.

Cons: Unprotected Capacity is less than 2400mah.

Other: Again a good bargain here at DX. Will buy several more to power my flashlight

Pros: - cheap - Good capacity

Cons: - Not protected

Other: Will get more of theese!

Pros: Cheap. Ok quality

Cons: The mah rating is probably a little overrated.

Other: Worked fine in mine ultrafire c2.

Pros: Great batteries. Use them all the time on my flashlights that I bought here!

Cons: They're not protected.

Other: Another great bargain from DX!

Pros: They are cheap. Also the effective time of working is good. I'm satisfied and'll buy them again :).

Cons: Those are NOT Batteries but Rechargeable Cells ( see photos attached by me ). Inscriptions on the Cell are: "TR18650 2400mAh 3.7V" and "WARNING.The voltage of full charge and cut-off discharge is 4.2V and 2.75V. Don't heat, indicate or reverse polarity.".

Other: Those are NOT Batteries but Rechargeable Cells ( see photos attached by me ). Inscriptions on the Cell are: "TR18650 2400mAh 3.7V" and "WARNING.The voltage of full charge and cut-off discharge is 4.2V and 2.75V. Don't heat, indicate or reverse polarity.".

Pros: 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.

Cons: After fully charged, some read at 4.2V, which is still within tolerance. The DX stock number sticker can be hard to peel off.

Other: If you need some 18650 cells, buy these. Don't bother spending more money on them, as all cells decay over time. I'll buy more whenever I need them.

Pros: 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: Cons: Those are NOT Batteries but Rechargeable Cells (). Inscriptions on the Cell are: "TR18650 2400mAh 3.7V" and "WARNING.The voltage of full charge and cut-off discharge is 4.2V and 2.75V. Don't heat, indicate or reverse polarity.".

Other: Buy you wont find better at this price
