Pros: These batteries are awesome they are so powerful!
they go good with laser - i bought a high powered laser (400 mW) and used these batteries and it's better then ANY other battery i bought!
and I have to say that all the stores that sell these batteries near my house was selling it for 5$ EACH Battery wich it means the price here is super cheap!

Cons: There are NO Cons!

Other Thoughts: these batteries are good for:
1) Lasers
2) Cameras
3) Small toys that require a lot of power!

Bottomline: It's very good and POWERFUL batteries!

Pros: - very cheap
- it works great with the red laser (200mw)
- good package
- pas cher contrairement au commerce local
- fonctionne tres bien avec le laser vendu sur dealextreme

Cons: - it's not exacly 3V 
- les piles ne font pas exactement 3V comme indiqué sur l'emballage

Other Thoughts:

Bottomline: I use 2 batteries for the laser so a pack of 4 or 6 would be better
sorry for my english ;)
Vendu par 4 ou 6 sera mieux qd on les utilise par 2
20 jours pour l'envoi vers la France

Pros: - 5 unit pack!
- Great price!
- I have been using a pair of them since I received them, and have no concerns about their charge and life.

Cons: Would be better if they sold them in 6 unit packs...
I would prefer to have a sixth battery instead of the fancy packaging (individually-packaged batteries may be convenient for storage, but this is not so useful if you want to store them directly in an specific box).

Other Thoughts: Useful batteries.
I would recommend everybody to buy rechargeable batteries and chargers, and use these only in case of necessity.

Bottomline: Buy them. High quality batteries have never been so affordable!

Pros: These batteries cost a fortune in Canada; They are so cheaply priced here at Dealextreme! they work great in my 200mw laser, and I have not had to change them in over 2 weeks with moderate laser use at school.

Cons: I wish they came in a 10 pack or 20 pack. I also would love to be able to use them for other electronics.

Other Thoughts: These batteries are really panasonic so they are good quality batteries; great price;

Bottomline: Great Value; made by Panasonic, so they are reputable; They last long, and will make your laser shine GREAT!

Pros: Wow, What a great price. I got five, for what I would have payed for just one.
CR2 batteries have a long shelf life. Usually 10 years. With a brand name like Panasonic. You can trust them to be left in your emergency flash light for years. With out fear of them leaking.
I tested the batteries, four of them put out 3.08V, Good!

Cons: One of the batteries was a dud. I tested it and the voltage was 1.98V Not the 3.0V that it should be.

Other Thoughts: I liked the way they were packaged. Each battery was individually packaged. I like this, as I can through them in drawer, and know which ones are unused.

Bottomline: Even though I only got four usable CR2 batteries. It's still a great deal. I'm sure the one dud DX sent me. Is very rare. That I would even think twice about ordering this same item again.

Pros: The price. Buying in bulk is always good value. This is no exception.
Also, it's a well branded battery, so it's charge and life has been excellent.
No problems with leaking batteries - a sign of batteries stored in poor condition and/or of low quality.
Five pack is very convenient; when one goes flat, you've got another and another and another etc.
Batteries come in proper packaging.

Cons: None whatsoever.

Other Thoughts: They're batteries. Doesn't get much simpler than that.

Bottomline: Cheap but excellent. Much better value than purchasing locally.

Pros: - Very affordable. Five batteries for the price of one (around here).
- These batteries hold charge very well and discharge fast enough for every gadget using CR2s I have.
- Individually packed.

Cons: - Individually packed. For my purpose bulk-package would have sufficed just fine. This fancy packaging only takes valuable space in my drawer so get your scissors ready.

Other Thoughts: I mostly use rechargeable batteries, but ofter carry non-rechargeable batteries as backup. At this price I can even afford to lose a few. ;-)

Bottomline: Branded, quality batteries for bulk price.

Pros: cheap batteries, use these on my uniform for work and cannot complain, easy to give out tickets and see. also great for blinding suspects, brilliant. also loads cheaper than the ones at work - £6.99 for one?! wtf, and even on staff, still a lot of money!

Cons: packaging is a bit useless - the bag is cheap, but who cares, its all a saving

Other Thoughts: would be good to have maybe packs of 10, maybe 20, and maybe some offer on buying CR2 batteries with the red laser or with some of the torches

Bottomline: good quality batteries at a great price, cant complain

Pros: cheap cheap cheap cheap cheap cheap cheap cheap cheap cheap cheap cheap cheap cheap cheap cheap chepa cheap cheap cheap cheap
cant say more awesome priced CR2 batterys
in germany it 10€ for ONE of these
so i saved about 90€!!!!
unbelivable
they come single packed in little plastic bags
hold out ling in the 200mW red burning laser with focus

Cons: nothing reallly!!!!

Other Thoughts: the package was opened by the german customs

Bottomline: buy them if you need chead cr2!!
good batteried for the 200mW red burning laser!!

Pros: CHEAP! And Panasonic labeled, so you can expect quality. Individually packaged, so easy to store, can be fitted in a smaller bunch if the space requires.

Cons: Not much, the wrapping that is directly on the battery is a bit crumpled, so it may cause some trouble if the device, that these are supposed to be used on, has a tight fit for batteries.

Other Thoughts: Do not confuse with CR123, as I did :D Altough they work with my flashlight after some tinkering, not the best fit though. But they work and the flashlight shines light, that is the most important thing..

Bottomline: Cheap batteries if you need them for a camera etc. These cost about 3 euros each here in Finland, so you'll save a lot.

Pros: Great item once again from DX.price is awesome and quality is as you would expect from Panasonic.I put 2 of these in my 200mw laser pen over a month ago and i can still burn holes in my socks when standing.

Cons: Only real con is the fact that it's a 5pack.My laser takes 2 at a time.I'm not too worried though,at this price I'll just buy more.

Other Thoughts: Maybe the shipping could be faster,but again i cant complain because it's free.

Bottomline: If you need CR2 batteries...These are they.Good price,high power and long lasting.

Pros: - Works great for alot of purposes
- Less the 1/5 of what one costs in sweden
- Perfect gift for friends that you like
- Your friends will think that you used alot of cash on them (its the thought that counts)
- Works just as fine as the really expensive here in sweden

Cons: The only real con is the shipping time and the date not being labeled but really.. free shipping and 15% of what the price is in our stores here... If you have the patience to wait like 1 week.. why not?

Other Thoughts: But them because they are really great cheap and are almost always in stock

Bottomline: Cheap batteries, comes in 5-pack, (almost)always in stock, panasonic brand (known brand), fast delivery, i'm an happy customer of Dealextreme

Pros: The price is good, they work fine, they don't seem to have any trouble.

Cons: They have no expiry date on them. They are not packaged on a blister, they are individually packaged in plastic bag.

Other Thoughts: I've used other CRxxx batteries from local stores, and the only difference I've seen on them is the price. Those are cheaper (several times) but not worse...
If you dont have have to use them inmediately, they are a great option.

Bottomline: There is not anything else you can ask to a CR2 battery... They work as they should, so if you need them they are a good buy.

Pros: + Individual package
+ Charged at 3.24v
+ They seem to be genuine branded Panasonic
+ The price o a five pack is the half of just only one in a big store (so it is a 10x less)
+ They are a "ready to use" alternative to rechargeable batteries

Cons: - Not a "best before" date marked (strange for a well known branded battery...) but, since the voltage is ok this is not a major issue.

Other Thoughts: I have tested on my flashlights and they work fine. Runtime is more or less the same than rechargeable batteries.
Great deal if you don´t want to complicate with rechargeable batteries, charger and so. Good quality, good performance and always ready to use.

Bottomline: If you need primary CR2's this the best and low priced option. Buy a couple of packs and try.

Pros: - Genuine Panasonic Batteries which are Made in Japan
- Such a great price, normally the price for just 1 battery costs more than this 5-pack- great value for money!
- You can't get a better deal anywhere else for CR2 batteries, especially Panasonic ones.
- All individually packaged in retail packaging

Cons: - Not really a con but some of the packaging came a bit bent

Other Thoughts: - I used some of these with my 200MW Laser SKU 11315 and they work well

Bottomline: Another great deal so if you need CR2 batteries then buy these!

Pros: These CR2's deserve 5 stars everywhere. It the cheapest price you will find for a good brand (Panasonic) CR2 batteries. There easy to use a fit my lasers nicely, have a good build quality and packaging and are useful for cameras aswell

Cons: No cons!!! These Panasonic CR2's are really as good as they seem. Each battery has his own package, but thats not really a problem.

Other Thoughts: It would be nice to have the "use by" date written on them, or on the package. Now it might just be guessing about when they might start leaking, if they ever leak at all offcourse... :-) I thought they where way bigger, like C batterys, but they fit 3/4 times in it!
Great prestation for this size!

Bottomline: These batteries are just good value for money! If you need them, buy them here, nowhere are they cheaper as far I could find.

Pros: Genuine "Made in Japan" branded Panasonic batteries.
Quality looks good, price definately is OK. Have not tested durability yet, but I don't expect any troubles there.

Cons: Mine came sealed in plastic separately, so no cardboard retail package with "use by" date. Also, I cannot find a "use by" date on the batteries themselves. I don't care about how they are packed, but it would be convenient to know the "use by" date. Perhaps it's on them, but then probably in Chinese?

Other Thoughts: It would be nice to have the "use by" date written on them, or on the package. Now it might just be guessing about when they might start leaking, if they ever leak at all offcourse... :-)

Bottomline: These batteries are just good value for money!

Pros: These CR2's deserve 5 stars everywhere. It the cheapest price you will find for a good brand (Panasonic) CR2 batteries. There easy to use a fit my lasers nicely, have a good build quality and packaging and are useful for cameras aswell

Cons: No cons!!! These Panasonic CR2's are really as good as they seem.

Other Thoughts: Should come in a even number pack. Most things like the 200mw red here take 2 CR2's so you have on left over unless you buy 2 packs.

Bottomline: HEAPS cheaper then shops!
Panasonic Brand
3v
10 year use by date

Pros: These are great batterys, they worked way better then I thought with my 200mW red laser.
I just bought 6 5-packs more, I can never get then so cheap here.
They cost around 5/6 euros each!

Cons: Each battery has his own package, but thats not really a problem.
I don't know how mutch mAh these are.

Other Thoughts: I thought they where way bigger, like C batterys, but they fit 3/4 times in it!
Great prestation for this size!

Bottomline: If you need them, buy them here, nowhere are they cheaper as far I could find.

Pros: These batteries are very high quality, they are genuine Panasonic and come packed individual.
- They are genuine.
- Packed individual.
- Cheap, you manage to find them here locally you can get 1 cell for the price you can get 5 on DX.
- My red 200mW laser does what it supposed to do with these.

Cons: - 5 is an logical number for batteries. (I bought 2 packs)
- A lot of waste from packages

Other Thoughts: I would buy this if you have lasers using these, since rechargeable batteries can be unstable = overload.

Bottomline: Top cells for a top price

Pros: THEY ARE SO CHEAP COMPARED TO LOCAL
I have looked for these locally, and here in Canada, at a dollar store, they are being sold for 5$ for one....(i dunno....it is the "dollar store with more"....)
They all came charged properly and all of them were in their original packaging. And are built well

Cons: Nothing really, just the packages are all written in Japanese...i think....but really, how hard is it to know what to do with it....

Other Thoughts:

Bottomline: Really cheap, works well and good brand name
If you need a CR2 that is cheap and works, get these....they are great so far.

Pros: HEAPS cheaper than the retail for similar batteries here in AU (Was about $12 for one at a shoe-repair store)
Work for a long time with the 200mW red laser and mine still melts black and sets matches on fire.
It is a 5 pack, can you believe it??? 5 Batteries, that is 2 red 200mw lasers and a green 50mw laser AT THE SAME TIME

Cons: 5 is an odd number and my laser takes 2 which is an even number meaning I would have to buy 2 packs or anther even number of packs to use all of the batteries

Other Thoughts: CR2 batteries are alot smaller than I thought they would be.

Bottomline: Excellent batteries that seem to last for ages on high powered devices. Get them for the 200mW red laser

Pros: These things are very cheap. In Australia, it costs about $8 to buy a single one, so this is a very good price

Genuine? It looks like a fairly genuine Panasonic CR2 battery.

Cons: I bought this to power up my laser, and in one day of fairly heavy use, the output dropped heaps. No more lighting matches :(

But that isn't really a problem with these batteries.

Other Thoughts: Nada. These are just great.

Maybe make some higher capacity ones though?

Bottomline: Buy these for your DX 200mw Red Laser (sku.11315)

Best value you'll find anywhere.

Also, buy 2x of these when you buy laser. 5 batteries = 2 sets plus 1 left over. 10 batteries = 5 sets ;)

Pros: * Genuine Panasonic

* Strong ( came >3v! )

* Very low priced!

* Stable.

Cons: None really.

Other Thoughts: 5-pack for only a bit over 7 dollars, wow.
Can't get them (genuine panasonic) cheaper
at any store that I can think of really.

My laserpointer just loves them, and they
arrived @ a bit above 3 volt. Thus full.

These works very good with those high
powered laserpointers or flashlights!
Does not drop power after a few seconds.

Bottomline: I doubt you can find them any cheaper
anywhere in Europe. They are very good
for strong laserpointers or flashlights.

Truely recommendable!

Pros: The batteries are really cheap for what they are. It works out at around 70p each for individually-packaged branded batteries. The supermarkets around here are selling these for upwards of £3, so this represents a real good saving.

The voltage of each one was above 3v, so they have arrived with a full charge. As I mentioned, they are individually packaged so theyre's no chance of them shorting out against each other.

Cons: No cons whatsoever at this price. You won't find these cheaper in the UK, so do yourself a favour and give DX your business.

Other Thoughts: I bought these for the DX 200 red laser and now I see the form-factor, I like how dinky they are, so I'll probably buy some CR2 torches for my burgeoning collection. I've also ordered some rechargable CR2 batteries + charger. I'd been a convert to CR123a and more recently 18650 batteries, but these little suckers offer a decent capacity at a fantastically small size. Will be looking to get a Q5 CR2 flashlight now.

Bottomline: As I mentioned earlier. Give DX your money and buy lots of these batteries - you will not find them any cheaper!

Pros: Very heavy duty battery with a stable output
Ideal for laserpointers >80mw
Trustworthy brand (Panasonic)

Cons: none so far

Bottomline: Great batteries for my 100mw laserpointer, deliver a constant voltage necesarry for a stable beam.
