It is one of my ebay deals- I swear by it- Had it for over two weeks.- Since about 9am (full charge when i put on my new OS system, to now, i have only used 25% with medium use.) As stated in the linked post, I actually have found about 20% increase with 1600 Mah battery along with not having to replace the battery door as you have to with larger batter. My 2 cents.
Thanks for the info polar! I love eBay too! I had been looking for a new battery, and this helped a lot. I went ahead and got one on eBay thanks to you! Now I all I have to do is wait for it to arrive!
