I bought a Lenovo G555 a few days ago, and I'm considering buying a back-up battery for it. But I have some trouble finding any store or site that sells them here in Sweden. Or rather, I have trouble finding anyone who sells batteries specifically for the G555.
Is there any other Lenovo laptop model with the same type of battery as the G555, which I can buy to use in my laptop?
You can look for spare parts for your ideaPad, ideaCentre and Essential series of systems from Lenovo official spare parts site here (to US only): http://www.lenovospareparts.com/
By checking out the website, the part number for your G555 is:121000792
According to the website, G450 is using the same battery with the same part number, too.
