Great cells. Will buy more – Ultrafire 3.7V 18650 2400Mah Battery Reviews

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 stock number sticker can be hard to peel off.
I'll still buy more, even if the price goes up to $5.
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.
