I remember that when I bought this battery, I was advised to leave the charger plugged in for a little more than an hour after the charging level reaches 100%. And for the subsequent times, try to avoid having the charger plugged in when the battery charge level reaches 100%. So I was following that criteria.

Perhaps the ultimate test is going to a business where they have original Lenovo components, ask them for a new battery to test it at the moment with the notebook and, if all goes well, then buy it. Thanks for your reply. Kind regards, Daniel
