Pros:- I bought 3-pack for replacing old cells in Thinkpad 600 battery.The runtime is now about 3 hours. Enough for me, despite if the battery capacity isn't real.- Price-ratio is great. New battery for less than 20$ (3-pack).
Cons:- There is no solder-tab on minus pole. But it is possible solder a tab if you have good lead-tin and flux. Of course, you have to solder quickly and be very carefull.
Other Thoughts:Replacing the cells to Thinkpad 600 battery was easy.Just unwrap the gray "Trustfire" capsule (there is second capsule under) and remove the + pole knob. There was a ready solder-tab under the knob.Then I grind/cleaned the minus pole slighly, put enough flux and then quickly soldered the batteries in place.
Bottomline:If you want your old notebook to mobile again, these batteries are good to use when replacing cells.But check first that:- Old cells are in 18650 form.- The battery is not a smart one, which remembers old cells condition.- You'll handle the risks and soldering.

Nice batteries, but not for laptop

Pros:Nice quality so far - I see no degradation after 3 months of heavy use.
Cons:Seems to be overrated - mine can hold only 1900mAh when used as replacement in my good old Thinkpad T43.
Other Thoughts:With these spacers on + terminal I don't need soldering - they fit tightly inside battery case, providing good contact. On the other hand - the whole battery is a bit wider now and comes in my laptop not so easy as before. So I don't count this as pro or con.
Bottomline:Nice cells, but not for refilling laptop batteries. Next time I'll try something other.

Pros:- Excellent quality- No leaks- Good mah- Lasts a nice time on a flashlight- rechargeable- They are cheap
Cons:Haven't found any cons really..
Other Thoughts:You should buy a charger with these. Also buy spare batteries if you are using these with flashlight. They will probably come in handy. I have had these batteries probably almost a year now and they are still working greatly.
Bottomline:If you are looking good batteries for a flashlight or whatever then you should get these because these are working greatly even after many many many charges.

Pros:These batteries make good replacement batteries for notebook computers that use this type of cell in their battery pack as well as tools that use lithium ion packs.
Cons:To build a battery pack, or rebuild one you should use a battery tab welder, the only con about this is the fact that DTW does not carry one.
Other Thoughts:If you are purchasing this product to use as something other than a replacement cell, be sure to pick up a charger to go along with them as lithium chemistry batteries require a very special charging circuit and if charged improperly will erupt in flames/explode.
Bottomline:DO NOT SOLDER THESE BATTERIES

Great batteries for this price

Pros:I also used the cells to replace my dead laptop battery cells witch lasted 5 minutes. After replacement I can run my laptop for 1h30min witch is great for my old, powerdraining laptop. The shipping was fast and the item was well packaged.One great thing was that the positive side of the battery has a hole for easier soldering. I
Cons:- Well I'm not putting a 5 on price since cheaper is better. - I know that you shouldn't solder directly to the battery but I did and it would be awesome if the battery had a ruffer surface on the negative side for easier soldering.
Other Thoughts:Great product for that price. The batteries seem to be holding the charge just as well as the original batteies in my laptop once did.
Bottomline:If you need 'em, buy 'em!
