    I got these as extras for a new flashlight I bought. I discharged them all the way, and had a few more times of charging them up and discharging, and everything seemed to be as advertised.

    They work well, and I recommend this product.

    These batteries work exceptionally well, especially since they are not a big name brand like LG or Samsung. I have been using them in a small LED flashlight, and even though they are only 350mAh, the light still last for a good bit of time. I tested all 4 batteries on my Nitecore Battery Charger/Tester, and all of them passed. When I received them, they all had at least 3.6V in them so there was no worry about them being bad form the start.
    From what I can tell the are not Low Voltage protected, so be aware of the usage of the batteries to prevent running them down to their Point of No Return (PNR). Once they hit the PNR, you might as well chuck them. I haven't seen a Li-Ion battery yet that would work right after going down to the PNR, even the big name brand ones (some people claim you can recover them with special chargers, but I am skeptical). If you ask about the minimum voltage for a Li-Ion battery you will get different numbers depending on who you talk to. I say that they should never be taken below 3.0V (Under Load) or 3.2V (Static). Others will say never to take them below 3.5V, but I have taken them down lower than that and 99% of the time, they charge back up like normal. The reason you don't want to past the PNR is that with Li-Ion batteries, when the voltage drops down so far it causes a chemical reaction with the electrolyte in the cells. This reaction in turn causes an increase in resistance, which will cause a build up of heat when charging. This very reason is why you heard about how dangerous Li-Ion batteries were when they first started to come out on the open market. Even today Li-Ion batteries can be dangerous if someone is using them irresponsibly, unless the cells include a integrated circuit (IC) for low voltage protection.
    As for these batteries, if you are competent and use them responsibly, you can't go wrong with purchasing them. If you are scared you might discharge them past the PNR or don't pay attention and take care of your electronics, than I would suggest getting some that have the IC in them.

    These are great cells. Note that they will very quickly destroy anything that cannot handle their voltage (lots of led bulbs, laser drivers, some motors), but will absolutely gigacharge whatever can handle it. Not all products have voltage rating but it was worth the risk to see some dollar store nail file spin a dremmel. My red laser diodes have fared best with the higher voltage. For tubular battery packs (think dollar store flashlights) just wire in parallel by linking the contacts on each end of the housing, then lining up all of the batteries in the same +/- orientation.

    These are NOT standard aaa 1.5 v cells. As the listing states. They are small li-ion cells similar but much smaller to the ubiquitous 18650.
    They don’t have active protection circuitry for over voltage, under voltage, or short circuit, but do seam to have overheat and over pressure protection. On cell tested overheat prevented over pressure.
    Tested cells ranged from 304mAh to 362mAh at 0.2C.
    These seam to be a very convenient form factor for hobbyists using them in small projects not requiring a lot of power(less than 1 watt). One of my expected uses.
    These should be stored in fitted container/case and not allowed to short. In applications using them they should be used with a protection circuit matched/modified to fit the characteristic of the cell.

    I read both good and bad reviews on these batteries. They all arrived at about 3.7v. Two took about an hour to top out at 4.2v while the other two took over five hours to reach 4.2v. The mAh capacity for each was different as well. It's a good thing the price is fine and they come with four of them.

    All of these cells worked well except 1 of them which either can't provide more than 2volts or can't provide more output than a regular 1.5v aaa. Tested with my lumintop gt nano and it worked until I got to the 4th one and then it would not power the light even in moonlight mode. Suspected Voltage issue. Tested in my lumintop aaa tool light (a 1.5v light) and it would power the light on low mode only and even then the output drops dramatically from 20 lumens to .5 lumens in about 2 minutes, any other modes would turn the light off until low was re-selected. Basically use the products image as a "3 work 1 is doa" which honestly I'm not mad about because I saw that some people were having issues with 1/4 of their batteries. Just wish there was better quality control.
