Ultrafire 3.6V 880mAh LC 16340 Protected CR123A Battery 2-Pack

Pros:

cheap, rechargeable, 2pack. for this price you really can't go wrong. I've used them a lot in the ultrafire a1 and they still work, i mean, they're batteries, they're supposed to work

Cons:

none, they are just a set of batteries, what can i say

Other Thoughts:

bought these with my UltraFire A1 Cree Q5-WC 5-Mode 230-Lumen LED Flashlight - Grey (sold on this site as well). they haven't let me down once yet. i haven't got any other electronics that need cr123 cells so i can't tell you how they work in non-flashlights XD

Bottomline:

buy if you need em! :D buy 2 sets or 3 or...

Pros:

Good lithium-ion rechargeable batteries. Ultrafire has some out there that look like this that I bought off an online auction site, and they ended up being too long and out of spec. Way longer than a standard CR123. These cells here are just the right size and are the same height as CR123's so buy with confidence.

Cons:

Sometimes the protection PCB on the bottom of these cells is not perfectly aligned 0 degrees to the cell. If you set the cell with the negative side on a flat surface some cells appear to lean a degree or two one direction. Not a big deal, as they still work perfectly, just a minor annoyance. Also, I'm sure the 880mAh is a bit overstated.

Other Thoughts:

Make sure if you use two of these in series that your light is able to handle 8.4v. Some are not and will burn up.

Bottomline:

Cheap, works.

Pros:

Acceptable batteries at a good price
and that DealExtreme has free shipping makes it even better

Cons:

But a bit misshapen. I had 8 from the beginning but has only six left,
Two of them have decided to not work any more, but at this price you can afford with a couple that does not work

Other Thoughts:

a little dissatisfied with the batteries due to the bad quality, but at this price, you get to count on it.

Bottomline:

good batteries to a good price.
so even if they are not the best quality I will buy more Ultra Fire 3.6V 880mAh LC 16 340 Protected CR123A

Pros:

it is well built
came charged
fair price

Cons:

none really

Other Thoughts:

i used this with sku.2097 which i also wrote a review on...it does its job and makes the light glow....the build quality as i said was good...haven't really tested how long it will last on my little glow stick...but after a couple of minutes the flashlight heats up a bit....maybe i need to test its endurance...hehehe...either the led will give way this will burn the flashlight...hehehehe...will update soon

Bottomline:

buy it for your CR123A needs...its a good buy!!

Pros:

Very well made batteries, shrink-wrap is tight, durable and provides adequate protection to the batteries during transport and use.

Cons:

These batteries are slightly longer than non-protected CR123a. So there might be some issues finding a charger that works with them and fits well.

Other Thoughts:

CR123 protected cells are very useful for normal use. Makes it no hassle to charge and no fear of it exploding or over-heating.
Charger DX sku.6672 works well with them and is dual voltage (110-220).

Bottomline:

Good buy, good quality, excellent price.

Pros:

This is a battery that fits a charger found here on DealExtreme Search for it.
if you have it than buy these batteries that last long and they are solid and useful
you save lots of money buy buying these batteries if not you would have had to buy batteries all over again every time.

Cons:

i have not found any bad things about these batteries yet.
they are keeping on strong

Other Thoughts:

its very useful and good for a cheap price buying these kind of batteries is expensive so its really recommended that you buy these

Bottomline:

Good batteries
Fits charger
Cheap
Lasts long
Recommended if you have a charger

Pros:

Protected batteries are always worth the money if you can find a charger that fits them. They disable charging once they reach the 3.6V. I purchased this with the SKU 01212 charger. Fits fine and does the job. I bought these instead of ONE 18650 battery for my UV light SKU 10709,

Cons:

I really can't give a battery a CON. Great price, free shipping, and a mess load cheaper than the local electronics store.

Bottomline:

If the device says (1) 18650, see if you can use these instead. It is a great rechargeable Li-Ion battery

Pros:

Cheap.
Equivalent to dozens of primaries.
Protected (for those who like protection circuits).
Good looking.
Both worked when received.

Cons:

I ordered these in May of 2008 and the batteries now have very little capacity, it has dropped through age rather than use. I could get about 40 mins runtime from both for at least the first year, but now I can get about 1/10th of that.

Other Thoughts:

Expect a shelf life of around a year.
Best to buy when needed rather than stock up.

Bottomline:

Alright for a while.

Pros:

This are powerful Li-Io Cells. I have ordered more than 10 of this items and every item is still working after about one year.
The protection circuit works well, and i would buy them again.

Cons:

None.

Other Thoughts:

I bought this batterys for Ultrafire Wf-502b Cree R2 5 Mode Lamp from DX to compare the light with one 18650. In general i would prefer to use 18650, they last longer and have the same brightness.
But there are smaller Lamps that need CR123, and for those Lamps you can take this cell.

Bottomline:

Good batteries for a good price.
Using rechargeable batteries is good for the environment and also for your wallet. Overall this item is a good investment if you are a frequent user of CR123A batteries.

Pros:

These batteries are just great.
The price is 1/3 of what they would be here in the states and they work just aswell.
They fit into a variety of devices, and the laser I use mine with holds them snug with no rattle.
They hold a pretty consistent charge.

Cons:

None, but work as advertised. packaging, while good, left a sticky residue on some of the batteries - nothing a little soap and water didn't remove. Also wish these where offered in larger bundles.

Other Thoughts:

If you need some rechargeable cr123's BUY THESE

Bottomline:

Just awesome

Pros:

Fit multiple flashlights nicely and all with no rattle. Work as advertise and don't get too hot.

Cons:

None, they are plain Jane, but work as advertised. packaging, while good, left a sticky residue on some of the batteries - nothing a little soap and water didn't remove. Also wish these where offered in larger bundles.

Other Thoughts:

Best to buy in bundles of 4 or more, if you buy just 2, and wait for delivery, you'll instantly wish you bought more.

Bottomline:

save the planet - recharge - save your wallet too.

Pros:

Rechargeable CR123A equivalents are much much cheaper and better value than buying CR123A in europe. These are less than half the price of throwaway ones over here, and will last for several charges.

Cons:

Be careful that your kit can handle these fully charged- they put out 4.20V which is a _lot_ more than the 3V normal CR123A provide. Expensive kit can be fried if you don't check first! There are 3.0V versions available elsewhere.
The bigger problem with these batteries is that the silver/grey plastic wrap on them isn't exactly cylindrical. There tends to be bulges and shape differences between the batteries which makes them difficult to fit in some flashlights.

Bottomline:

Good value, but inconsistent sizes makes them a gamble.

Pros:

I bought 6 of these batteries for use in the RC-F4, RC-N3, and RC-M4 lights. At first they worked well, the RCF4's lights would get very hot if left on more than 5 or 7 minutes. The batteries worked well at arrival, held their charge for a good amount of time.

Cons:

-- All 6 batteries only lasted a handful of charge cycles.
-- Eventually I'd put the batteries in the RCF4's I own, the light would turn on for about 1second and immediately cut off. A multimeter afterwards shows 0V from the battery.
-- Put back in the charger for just a few minutes they're back to 4.1V on the meter.
-- Then into the RCN3 and it too would light for only a brief second and then would cut off.
-- Very odd that all 6 of these batteries exhibit this exact same behaviour, all have probably 10 or so cycles/uses/charges before experiencing this problem.

Other Thoughts:

I'll try some 18650's where I can in some of my lights. Hopefully the quality is much better on those. These batteries have been the most disappoint DX purchase to date.

Bottomline:

I'll stick with the purple 3V rechargeable versions for now. Why is it so hard to make a good quality RCR123?

Pros:

Environmental friendly to use rechargeable batteries.
My flashlights seem to like them too.
They look and feel solid and perform as expected. Has the protection board and no memory effect. More than 2x cheaper than branded batteries. Seem to hold charge quite well also when not in use. Powerful light output when used on a flashlight.

Cons:

nothing that I can think of at the moment.

Other Thoughts:

none

Bottomline:

LiIon battery for low current application in the 123A for factor.
Can be used to double the voltage in a flashlight if used instead of 18650. Not all flashlight can take them though and it does not always make sense depending on how the flashlite regulated the driving current.

Pros:

Great battery for the price, CR123A does not exist in Australia so I bought these with sku.4151 as recommended by others.

Cons:

I can't see any cons, I've had them in 2 different torches sku.23652 and sku.26792 they work great.

Other Thoughts:

Cheap and affordable, they work fine. I'd recommend them to other people over say a AA battery due to the increased voltage.

Bottomline:

Cheap batteries, no problems so far, I haven't tested recharging...
There were no modifications required to fit in the torches I bought, they dropped in without issues and both were well powered and very bright.

Pros:

+Small form factor
+Good capacity
+Protected

Cons:

-No battery holders available on DX for it!
-No high current discharge

Other Thoughts:

I used it for modding a portable speaker. With a available battery holder that would have been easier but it still works.
If anyone is looking for LiIon batteries in AA size they can be found on DX too.

Bottomline:

LiIon battery for low current application in the 123A for factor.
Can be used to double the voltage in a flashlight if used instead of 18650. Not all flashlight can take them though and it does not always make sense depending on how the flashlite regulated the driving current.
............................................
............................................

Pros:

-very cheap ,much more cheaper than disposal battery.
-Charged right up to 4.2v with TrustFire All In One charger which sell for under $9.
-Friendly use, and does not get any hot when fully charged.

Cons:

-little bigger than it type, so it may not fit in some device use same type, No Problem for Flashlight.

Other Thoughts:

nothing i can think of, it said pcb life 10 years, this may over rate ..i very happen if it's die after 2 years or after 50 charged.

Bottomline:

I already bought 2 packs, will buy few more pack for spare...

Pros:

Enviromentaly friendly to use rechargeable batteries.
Wallet friendly to use rechargeable batteries.
My flashlights seem to like them too.
They look and feel solid and perform as expected.
Seem to hold charge quite well also when not in use.

Cons:

Less capacity than promised, I think.
Thinner than 18650s so they ratle a bit in my flashlight. I just might Shrink tube them ;-) Not really a con, just as info.

Other Thoughts:

I wanted to see if my flashlight would perform better or worse with these than 18650s but atleast with naked eye seems the same. As it should be, but you never now. Don't know about run time.

Bottomline:

Stop waisting money on single use cells and get these. They save the money back in no time at all! And the planet & wallet thank you :-)

Pros:

Has the protection board.
More than 2x cheaper than branded batteries.

Cons:

Lower capacity in comparison with the advertised.
A bit longer than primaries, therefore could not fit all devices well.

Other Thoughts:

Test results:
1-st:
Discharge Rate: 0.50 A
Starting Voltage: 4.12 V
Ending Voltage: 2.80 V
Total Time (hh:mm:ss): 1:04:26
Tested Capacity: 0.54 Ah
2-nd:

Discharge graphic - http://talks.guns.ru/forums/icons/forum_pictures/001518/1518600.png

Bottomline:

Good rechargeable batteries.

Pros:

Good price
seem to have good capacity
work great

Cons:

none really, capacity may be slightly overstated

Other Thoughts:

They work well in all of my flashlights that take cr123
They are a little longer than primaries, but not a lot
just judging by runtime of my lights i would say they are pretty close to stated capacity, maybe overstated by just a little, this is not based on any measurement just an estimation based on runtime.

Bottomline:

Stop buying disposable batteries. a couple sets of these and a sku 1236 and your set. they will pay for themselves in just a few recharges.

Pros:

Best price on LiIons around. Protected circuit works flawlessly. Great for anything that will accept the slightly larger size. Charges very well and excellent cell life and shelf life.

Cons:

None I can think of. Maybe in some devices these are a little too big (but I have not found any)

Other Thoughts:

These are great if your sure your device can handle the extra size and voltage. These batteries are CHEAPER than the Primaries sold locally- and they are rechargeable. Normal safety precautions should be used (never leave unattended, never place on a flammable surface, monitor condition of battery and charger, discard in proper manner if any damage appears)

Bottomline:

These are great! I have 5 or 6 sets and all have worked flawlessly. These ROCK for LED lights!

Pros:

Cheap and come full charged. Low price, but good looking. You can also find the charger in DX at low price.




.

Cons:

I haven´t found any yet. Well of course they don't last the same as no rechargable ones.

Other Thoughts:

I bought them for my latern and I didn't realize that the voltage was 0.6 higher than the used ones, so I broke the bulb. But no problem in DX you can also find bulbs for this voltage.

Bottomline:

Recommended product

Pros:

Very easy to use, no worries about overcharging / overdischarging.
Price is right.
Build quality is acceptable

Cons:

Double and triple check that these will fit in the devices you want to use them in (use the DX reference picture). The PCB adds some extra space to the back of the battery. In addition, if the build quality is subpar, your battery might have a larger diameter due to the PCB/wire.

Other Thoughts:

The other "Trustfire" branded protected gray RCR123s seem to be nearly 1 - 2 mm shorter. In addition, they are also ~50 cents cheaper. I ordered those instead this time.

Bottomline:

These are great batteries, but I'd order sku 19627 now that I know they exist.

Pros:

arrived very quickly and in good condition
The protection is very good.
PCB life is around 10 years.
Good batteries for a good price.

Cons:

No cons for these batteries, none at all!
Buy them or i will cry.

Other Thoughts:

They are protected, to ensure your flashlight won't break. I bought 24 of them for several ROMINSEN RC-F4 Q5 modded flashlights.

Bottomline:

Get a decent charger for these and buy a few sets.. They work great and flashlights seem to work well with these.. The protected feature is a must nowadays as it can prevent these from causing serious damage or hard if overcharged..

Pros:

Lasts long and protection works great.
Charges fairly fast.
Cheaper than many others (these cost up to 20$ in a store for a single one!)
Looks good.

Cons:

If you have a single-size charger for these, they might be slightly longer than normal ones. You can just squeeze them in though.

Other Thoughts:

The cover does not peal off accidentaly, but you can get it off without ruining the battery if you want to make the protection slightly smaller. Wouldn't recommend it to people who have not dealt with batteries before though.

Bottomline:

Great batteries at a good price. Didn't have any problems and I will buy more when I need them.
Seem better than the others I have tried from DX. Buy it!

Pros:

mine arrived very swiftly and in good condition well packed-Good batteries these are a great buy for a good price. The protection is very good.What is good about these battery's is that they do not get too overcharged mine charged to 4.2 volts The charging time took an hour and they didn't get hot seem to work fine so far.TrustFire brand is a big plus,I got these to go in my romisen laser and they last ages

Cons:

NOT REALY CON'S BUT LOOK OUT FOR + They are a little longer than normal CR123A Battery's but if the item has spring's in the battery box they should fit ok --when they do go flat they go all of a sudden you don't seem to get a worning the power just go's

Other Thoughts:

mine charged to 4.2 volts---PCB life is around 10 years but i'd be amazed if the battery's last that long.I but I think you should get about 2-3 year's out of them (depending on usage ) 880mAh is ok for most thing's

Bottomline:

Good batteries for a good price. The protection is very good and allows for these to be used at the proper voltage without worrying about damaging the batteries.

Pros:

Good battery!!!!
pcb protected over overcharge, discharge!!!
they claims that the PCB life is around 10 years...
The price is very competitive for this kind of product!!!

Cons:

no really cons.
the battery are slightly more bigger than the unprotected type, but for mine projects fits good!

Other Thoughts:

seems very well made product at the right price!
they fits in my charger!!!!
good deal!!!! good price!!!

Bottomline:

great price! great service!! the shipment take 14 days to italy!!!!!!!!!
I can't see no reason to not get these cheap and useful battery. Go for it, should do the job!!!

Pros:

These batteries are very good. The build quality is good. They are 3.6v @ 880mA.
+Build quality.
+Ultrafire , although I don't know if they're genuine.
+Protected batteries so your device won't be damaged.

Cons:

-They are slighty bigger then normal CR123A's butt hey fit in my Ultrafire Q5 CREE
-Only 2 batteries for $5 , 4 batteries for $5 would be better.
-Not in retail packaging just wrapped in plastic.

Other Thoughts:

I used these batteries with DSD 18650 CR123A Charger Black and they work fine. They deliver good power for my flashlight.

Bottomline:

Very good protected batteries to be sure your device won't be harmed. The price is a bit high though in my opnion. But if you need protected batteries get them!

Pros:

These batteries are inexpensive and work well with my flashlight and charger. The Ultrafire labeling is of decent quality and the protection PCB adds an extra bit of security from overcharging.

Cons:

The packaging on these batteries state that the 'PCB life is around 10 years' so potential buyers should keep in mind that these batteries won't last for a lifetime. However, no batteries will last forever.

Other Thoughts:

I bought these batteries for use with a Romisen Cree RC-N3 (sku.9070) flashlight and charge them using a Nano Li-Ion Single 3.6V CR123A Charger (sku.998). The charging time took a long time with the Nano charger but there batteries seem to work fine so far.

Bottomline:

Using rechargeable batteries is good for the environment and also for your wallet. Overall this item is a good investment if you are a frequent user of CR123A batteries.

Pros:

Good capacity.
Attractive price.
Protected cells.

Cons:

Something after complete discharge (cut off), these are hard to charge - you place them in the charger, but they do not start charging. If this happens, don't give up... give it a few more trys (in a few hours).

Other Thoughts:

Seem to be identical with the TrustFire branded batteries.
Sometimes a review does not have to be over 500 characters to be useful!
--------------------------------------

Bottomline:

need a CR123 - these are a great buy. I have over 10 of these already. :) Get a few packs.
