The big problem with NOS battery is that sometimes its a gamble! I bought one off eBay for my x230 and I had to change it.

But the seller was cool enough to change it ( getting 4-5 hours ) and a smaller one which gets me around 2 hours more.

Yes it is a gamble but as I said, it is from Lenovo as well. The battery manufacturing date I got from a "new" one was 4 years old once.
