I have a 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: http://www.batteriamondo.com/lenovo-ibm.html , http://www.scontobatteria.com/dell-xps-l701x.html . So how to figure out which is mine? Any suggest is welcome.Thanks in advance.
