I want to get a Lenovo Thinkpad 13 with a 6-cell battery, but all I am seeing online is the 3-cell and it's not in stores at all. If I buy one with the 3-cell, can I buy a spare 6-cell and use that? Can I swap out one for the other?
If the six-cells battery is indeed designed for the same laptop range as the 3-cells one, yes, it should work with approximately double the battery life if they both use the same cell model.
Thank you -- I haven't bought the laptop yet because I can only find the 3-cell to buy, it is pretty frustrating. Nothing in stores, only online and only 3-cell. This way I can just buy it and buy the 6-cell for the same model. Thanks so much for the quick replies everyone.
