Pros: price,price,price = major no 1 pro, plus well put together cell come in purple/violet color and stamped 1000 mah so without checking probably 550+ at this money just the fact that they are well made and work well is enough, i`ll buy a few more as spares, usually use 16340 protected but some flashy`s wont take them so these are just the job.

Cons: not protected , but you knows that when you order, no cons as far as i can see just be careful with charging and watch the discharge.

Other Thoughts: best bang for your buck with 123 A`s buy some while available at this price.charge well in 06672 which is a wicked little charger.

Bottomline: bottomline is the bottomline= low price for decent quality cells.

Pros: Received batteries marked 1000mah.
Seem to be of good quality so far.
Charge just fine with the nano charger.
They will probably fit lights a little better than the protected ones.
Much more light from flashlights that can handle this voltage vs a primary cr123.

Cons: None really. Not sure if the 1000mah rating is accurate or not.

Other Thoughts: I've only charged them once with no problems.
Hopefully, they'll hold up. For this price I don't care that they're not protected. I like that they fit a little better in many of my lights. I'll do my best to keep from over-discharging them but for this price I'll just buy some more if that happens. A single 16350 light with a clip makes the best edc in my opinion.

Bottomline: Happy with the purchase.

Pros: - received 1000mAh batteries
- works exellently with the UltraFire WF-139 charger! no charge monitoring needed, the charger automatically shuts off (will need charge spacers).
- inexpensive: for around US$20 you can get the charger and 4 batteries, less than i've seen a 6-pack of disposables for!
- a fully charged cell will last for weeks of intermittent use in my NovaTac 120T, or a day or two of heavy use
- stays cool under extended use

Cons: - still not sure about how well they keep the charge under storage. i've used a battery that was charged >2 weeks before and it seemed to last less time, but i have to confirm this.

Other Thoughts: these work fantastically in the NovaTac 120-series. these lights specifically require UNPROTECTED cells, as specified by their manual, because the light has its own over-discharge protection. using protected cells can cause random light dimming as the two protection circuits battle it out.

Bottomline: this is THE best value for any kind of CR123 cell, wether rechargeable or disposable. i still keep disposable ones stashed in various bags, as they have an effectively indefinite shelf life - but they're really only for backups.
there is really little reason to go with disposables, especially for regular users like the law enforcement, military, aviation, and service inspection industries.

Pros: -Reasonably cheap
-3.6v Lithium rechargeable, according to what is stated on the battery 1000mAh (but I think it isn't the real deal.)

Cons: - unprotected (no over-charge or over dis-charge protection);
- I think that the stated capacity of 1000mAh is (greatly) exaggerated

Other Thoughts: If you can handle the risk of over dis-charging these are fine batteries.
still no 500 words so I have to think what to write more

Bottomline: If you have a good charger which takes care of overcharge-protection these are good batteries.
Inexpensive and very good
