I have a lenovo notebook two years old,and I need to change my battery. Nowaday,many laptop companies has different batteries, and some laptop companies have different batteries for different models,such as: lenovo thinkpad t420 battery . So how to figure out which is mine? Any suggest is welcome.Thanks in advance.
Very, very wrong forum to ask this question! 
// Per.
Why not look at the one you have now?
I would check the label maybe?
Isn't this thinly disguised spam and probably related to the lengthy post in French last week that also linked to a site selling laptop batteries?

You are probably right. Though I don't read French, so I missed that.
