UltraFire 10440 3.6V 500mAh Battery

• Other Thoughts: I was skeptical to try these batteries because these batteries can only be ordered online. I use these batteries for a flashlight and they work very well. Neither the charger nor the batteries get hot while charging which I'm glad of, so I would recommend these batteries for your flashlight.

• Other Thoughts: I bought these. Fast shipping and delivery. The batteries are perfect. I'm using them on a regular basis everyday. They are truly very good. The price is a little higher than what I get elsewhere, for the same specifications, but the product is definitely reliable. Yet very pleasing gift, as a welcome note. Thank you.

• Pros: great battery deliver same power for my flashlight as original that came with it
• Cons: none
• Other Thoughts: at first i thought it was empty but it wasnt turn out i put it upside down into my laser pen. Now when it's in good it delivers the same power as the original 3.7V 600mAh battery

• Other Thoughts: I bought these batteries thinking it will make a big difference in comparison to the regular batteries 18650 I usually buy....... <br/>It is the same thing. I think these batteries were a little stiff in price. <br/>They work the same as the ones I have.

• Other Thoughts: They are much, much cheaper than others in the market. This battery measure nearly 500mAh! they are good!
