Ultrafire 14500 3.6V 900mAh Protected Li-ion Rechargeable Batteries (2-Pack)

Pros: Battery seems to hold up well. Build quality is good.

Cons: Battery is longer than unprotected cells, they work in my Fenix L1D but it tooks some adjusting and it only works in turbo mode.

Other: If you need some 14500, give these a try. I was glad I did.

Pros: Great capacity and very well built, finish charge voltage is 4.17V.

Cons: None.

Other: This is a great, protected 14500. If you are looking for a 14500 this is the one!

Pros: Cheap 14500 size lithium.

Cons: Quality and capacity is not top quality.

Other: I choose this batteries because it is cheap with fair capacity. Stated capacity is not confirmed.

Pros: +cheap

Cons: -you get what you pay for (especially for batteries)

Other: nice price, nice batteries

Pros: They're cheap.

Cons: not as well build as name brands (Duracell)

Other: Like mentioned these are my first set. They're great so far.

Pros: - Cheap quality protected 14500 batteries - Works great in all types of applications (granted the applications are rated up to 4.2v inputs) - Color signifies protected status

Cons: -None

Other: Get them.. The UltraFire logo stamped at the negative end is a nice touch and adds to quality feel.. All in all I recommend that if you have a need for these types of batteries, these should be on your shopping list..

Pros: high quality, very cool ultrafire-logo at the bottom, they are cheap, they look very nice, they feel well in the hand.

Cons: about 3mm longer than an AA-batterie or the non-protected ultrafire 14500-batteries, you better check the lenght of your batterie-tube!

Other: nice 14500-batteries, but make sure, that they will fit in your flashlight. buy them! it´s a "must have".

Pros: Work well in my Ultrafire C3 Cree flashlight. it does seem a little brighter than using AAs, and the extra runtime is nice. I haven't done any run length testing, but I'm sure it has to last longer than normal NIMH batteries.

Cons: Not really any cons to speak of, besides the fact the mAH rating is overrated, but nothing new there I guess.

Other: They seem fine to me, they're protected so you don't have to worry about them blowing up in your pocket (not a good thing!).

Pros: - Has PCB protection to keep your batteries and devices safe
- Price is cheap compared to local stores that are selling them
- Works very well on all my flashlights that accepts this battery

Cons: - Build quality is questionable as I've got a dud one (brand new) out of the 6 that I bought. However, DX were very quick to replace it. One died around a week ago and wouldn't hold any charge any longer.
- Perhaps a better QC on these would be good.

Other: These are excellent lithium batteries for the price. Despite some QC needed, I would highly recommend these mainly for the protection it has built in.

Pros: Seem like they are good batteries.
I prefer protected batts. It has a flange that is not quite round and sticks out so I think they don't work in my units.

Cons: Didn't fit in my Romisen, well they looked like they fit, but when I close it up they don't work. I think the Neg end is too large it has a flange that is not quite round and sticks out so I think they don't work in my units.

Other: Could be fine batts but I was disappointed that they don't fit.
