I've been watching the performance of this battery since I purchased it to replace the OEM battery in a Lenovo X100e Thinkpad (which is a great little device). It holds a charge, but does not seem to last as long as the one that first came with the laptop. I have no scientific proof, but it's my observation. It was a little scratched up, too, further feeding my conspiracy theory that it was not exactly new. Hmmm....

Disappointed with this new battery; the original battery with this IBM Netbook had +/6 hours of work time, which has lessened over time to about 90 mins. This new battery gives a little over 2 hours, not enough improvement to have spent the money.

I believe I mistaken wrote a review for a different battery (Toshiba, which didn't fit), not the Thinkpad battery sold by this merchant The Thinkpad battery works great. Extends the charge to at least double that of the original battery by 2 to 3 hours. Well worth the money for someone who does not want to be plugged in all the time.
