Rechargeable 3.6V 18650 2200mAh Blue

Pros: Great value for the money.

Cons: None

Other: Good rechargable batteries.

Pros: First the pro points:
+ best battery/accu ever: great constant current and 1800mAh is just a dream, lasers and flashlights can go a long run on this.
+ nice coating, scratch proove

Cons: The negative points:
-sku sticker is difficult to remove :D
- came without a bubble wrap around it, just loose in package

Other: ideal for lasers and flashlights working on these babies.
Wouldnt wanna have another laser of flashlight, these ones are FAR better thar CR123A and CR2 batteries (not to mention AAA and AA..)

Pros: Very cheap. Saved me alot of money.
Gets the job done

Cons: Seems like the capacity is a bit overrated, but I'm not sure. I just didnt get the runtime I had hoped for - but then again, I never tried the laptop with the original batterypack.

Other: Worked like a charm replacing the old cells in my laptop - VERY cheap compared to a new batterypack.

Pros: It does what it's meant to. Non protected so it fits better in flashlights, haven't had any problems with over or under charging provided you buy a decent charger. Works well in my HA-III Cree R2, the storage is probably near what they claim.

Cons: None. No horrifically over-claimed storage capacities like some of the batteries here on DX

Other: It's hard to fill these boxes with 500 characters about a battery. The battery is blue. It's large and fits in my flashlight. I like it. What more can I put in here?

Pros: -capacity seems to be as what is claimed, I do not have professional test equipment but it powered my R2 light for more than an hour on high.
-charges up to 4.1V with my DSD charger, but I think this is due to my charger not peaking to 4.2V, this can be a con, but just to be on the safe side 0.1V is just minor.

Cons: -recessed positive terminal can be a con.
-you really have to see the label to make sure which side is positive.

Other: I have ordered another batch, but maybe next time I should try other brand/capacity, just to feel the difference.

Pros: + Very exactly 650mm long
+ True capacity! This is actualy 1800 mAh
+ Low drop in capacity at 1C discharge

Cons: - 18.2mm thick (tiny bit too thick)
- only 1800 mAh

Other: At very low drain it does indeed deliver advertized capacity and did not drop that much as I ramped up current. For flashlights or other low to medium drain application this cell will deliver as promised. (Not as labelled, but as promised by DX.)

Pros: - very cheap
- realiable
- in general, do what they should do ))
- works longer than protected ones because ahs no protection

Cons: - sometimes easy to forget where "+" and where "-"
- probably lack of protection is bad thing. however i had no chance to test it. i alway have spare batteries in my car

Other: good battery. does what it should do. but carefully whatch where "+" and where "-" when you use it

Pros: - It really has capacity as stated - Really good build quality (survived my hard handling) - still has nearly the same capacity even after about 90 cycles

Cons: - High internal resistance (woudn't recommend it for high current usage(looses capacity quickly and heats up)) - wount fit into some devices (a bit to thick (20mm)) but fo me its not realy con

Other: I would recommend it to anyone who dont mind the cons... Good and cheap battery for a change. Keep it up DX

Pros: Excellent battery, simple, easy to use, without inner protection for overcharge witch you don't need if you have good charger and you can use it on high powered flashlights without fear that protection will turn the battery off when you need it the most.

Cons: No cons, works great, last long time on one charge.

Other: If you need unprotected batteries, this is one to get, you wont regret.

Pros: Easy to buy, Drop Shipment and Gift Service, Tracking system, Stock ok.

Cons: The envelope was ok, but some boxes that contain a battery each one, arrived broken but the batteries were ok.

Other: Good tracking system. I checked it once a week and the package arrived as exposed in the system. Good and cheap battery for a change of the tired batteries of our notebooks and laptops.
