Poor battery, and not for high current applications.
By XYZZY
I purchased two sets of Ultrafire 18650 3000mAh batteries with charger. The included charger works well for travel needs but does not seem to have two independent charging channels, as there is only one charge status LED. It works well enough for casual use with inexpensive cells in my collection, but a higher quality charger such as the Pila IBC is a good investment if you get serious and want the most out of your more expensive 18650 batteries.

Batteries AND charger
By KAS114
One review wrote about getting the wrong charger. I ordered these batteries twice (one for a spare set). The 1st set, my order came from R-lsales which sent me the “mini” charger NOT seen in the photo. The second pair came from “CREE-Flashlight” and it was exactly what was in the picture, seems to work better, and seems of higher quality than the “mini” cheap plug in the wall thing. I feel like the springs are breaking every time I install or take out the battery. CREE-Flashlight also delivered faster than I thought possible – ordered Friday and had it on Monday. These batteries DO seem to last a long time. The charger light does turn green but if the batteries are real low, it might take up to 4 hours.

Waste of money
By SMC
I purchased these for a fenix tk 35 flashlight. Both batteries indicate fully charged in charger and charger shuts off. When put in flashlight the highest mode would not work. the light would turn on for a second and then shut off. This is what the flashlight does when the batteries start to die. My other AW and tenergy batteries will last me about 2 weeks of light intermittant use before the turbo mode will stop working. These wont work at all in turbo. High mode will work but I never left them in to see how long. I tried to charge them a couple of more times using a different charger but it was the same thing, charger would turn on then after about 1 min would indicate batteries fully charged then shut off. Contacted R-lsales via amazon and was given a address to send them to in California at my own expense. Shipping was going to be $12.00, cost of batteries were $15.00. Wasn’t worth the trouble. Waste of money.

Have purchased a couple of sets of tenergy batteries since and they seem to be working as good as the highly regaurded set of AW batteries I have.
