Ownership verified by DX Nice batteries, but not for laptop
Posted by RomByDan on 3/2/2010
Involvement: General (knows how to use it) - Ownership: more than 1 month

Price: starstarstarstar
Ease of Use: starstarstarstarstar
Build Quality: starstarstarstar
Usefulness: starstarstarstarstar
Overall Rating: starstarstarstarstar

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.

Price: starstarstarstarstar
Ease of Use: starstarstarstar
Build Quality: starstarstarstarstar
Usefulness: starstarstarstarstar
Overall Rating: starstarstarstarstar

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

Ownership verified by DX 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!
