    I wonder if anyone could help me clarify the following question: If an original Lenovo Thinkpad battery is re-celled by a dealer, do I have any way to check this without actually opening the battery? For example, will the Power Manager (I still use Win7 on my X220) battery info show this or not? Power Manager does display the manufacturer (e.g. Panasonic or Sanyo or LGC), the date of manufacture, the number of cycles, date first used and so on.

    The reason I'm asking is that I want to buy a X220 battery on ebay (UK) and the seller (a shop with 99% rating) describes it as genuine, original, brand new (though NOS, made a couple of years ago) Thinkpad battery with the correct FRU and everything but says it is "open box", that is, it's supposed to be new, in the original Lenovo box, but not sealed. Since the price is quite low (about 50% of similar ones in sealed box), I'm afraid it might have been tampered with (re-celled, hacked, who knows). But if I can check this with Power Manager, I'd take the risk and order, since in the worst case, I can file an ebay complaint

    You can at least see how many power cycled it's had.

    Not sure about the rest.

    Well, it's supposed to be new, so the power cycle should be zero. But the main point is how can I check if the cells are genuine, original ones

    You can't, there is no memory on each cell that states that data, only on the wrapper, but its pretty hard to open a battery casing without mark, just to replace its cells..

    New generally has 1-3 cycles from the manufacturer.
