    On first charge, it gave less than 600mAh from nominal 2400mAh. It took almost 10 cycles of charging, discharging for reaching maximum capacity showing these bateries may not be that much reliable. The protection circuit cannot be trusted as it does not cut off on low voltage. Did not test on It... Read more

    I like 18650 because they look different to disposable primary batteries. Too many times pricy AA batteries get thrown out because they don't look like rechargeables.

    pro: still using thoose in my flashlight, and now started to drain bit faster. I bought on 2012 dec. con: nothing I didn't measured the real capacity, it's enough for me.

    Average 18650 batteries for uses that do not need so many power. Declared mAh maybe higher than real.

    Pros: very good price, plastic box for battery Cons: you cannot believe number on battery (about mAh) so the time will show how good they are. but again for that price it is ok.

    I've ordered a few before, and I come back for more this time. Reasonable price, reliable quality, simple and effective.

    Item received in good condition. Used it and found not as good as previously ordered ones. The runtime is much shorter. One of them was not able to charge fully after 3 charging.

    Impression:drop in quality;
