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 DX 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

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!

Pros: This is the perfect battery for the White Light LED Flashlight + Emergency USB Charger with Cell Phone Adapters sku.18883.
I have bought these battery as spare battery for the USB charger.

Cons: Non other than the fact that it is unprotected and you need to use a correct charger.
The other issues is that the capacity is lower than the rated by 20% or it is only 80% of the rated capacity.

Other Thoughts:

Bottomline: As we always would prefer that the price is cheaper so that we could buy more units. But since it fit my sku.18883 I am very happy about it and should not complain too much.

Pros: I bought them to replace dead cells in a laptop battery, and they work fine. I soldered them and they took the heat well, I don't think it cause any problems with them so this made me happy.

Cons: I assumed the capacity would be lower than they were advertised, and I'm pretty sure they were. Not by much though.

Other Thoughts:

Bottomline: I guess people use these in flashlights? I used them in a laptop battery and I couldn't be happier. If you have an old laptop battery that can't hold a charge, open it up and see if these cells match. Buying these could save you a lot of money for a new replacement.
