Question: is this a genuine Lenovo battery in 2013 or not. I'm in Sri Lanka and a big problem if I get junk. Most of the reviews are so old not sure.....
Document: I was concerned after reading some of the reviews that the battery I would get would give errors about not being a genuine Lenovo battery, however, the battery I received is as authentic as you can get and it works just exactly like my original Lenovo battery.
This is Genuine Thinkpad Battery made by Lenovo, that price was best as I can find.The item is truly brand new because battery management tool says it was built on Feburary 1st 2008. No long stay in warehouse.3rd party battery might cause serious problem,I'd like to strongly recommend you taking genuine one.
The battery works fine however, everyday I get a message that lets me know this is not a genuine Lenovo battery. When I purchased this product I thought it was a genuine Lenovo product. If the battery that I already had wasn't totally dead I would have tried to return it.
I was wary of purchasing this after reading the other reviews - similar batteries are on sale as "OEM-equivalent" parts at a much lower price.The battery arrived in a Genuine Lenovo box - complete with hologram seal.Manufacture date was late 2010 - so sitting on the shelf for a while - but this is an older laptop and I guess inventory does not turn over so quickly.Happy so far - I'll give an updated review after a month or so.
With the old battery, my laptop froze even while plugged into house current. The problem went away with the new battery.
I got this replacement battery and it worked for hardly an year and now it's gone bad. I need to get another one now. I don't know if the problem is in the part or the laptop but seems like I got a bad deal
I assumed by the description given that this battery was a &#34;Lenova&#34; battery. My laptop says it is not a genuine &#34;Lenova&#34; battery and cannot guarantee the performance of my laptop with this battery. It does work but now I'm confident of it's longevity. We'll see.
Every time I turn on my Think pad I get a warning that this is not a guninue Lenovo battery.
What a shame Lenovo...  you've ruined your reputation in my book and I won't be recommending your laptops any further. If I had the opportunity, I would return the system for a refund and get her a new laptop with a battery that will last for more than a year.
Thank's Alot Using My Lenovo Battery Now.! I think it's great.Postage was good ,five day's and as Long as It keep's going awhile I'm cool. oops it just warned me It's running out of power it has charged 5-hour's Hum ???

Answer: The battery we received was a genuine Lenovo battery, and my husband should know, as he works for Lenovo.
