Query: bad product, bad seller

Apparently there is a subtle distinction between the battery (which has the same part number) used for a T60 and a T61. I could not find the use of the T60 in the information on the battery. It will not work for us. I tried contacting the seller and after several days, got back a message. I tried again explaining the issue and was told they did not have the type needed for a T60. I asked for instructions on how to return a brand new battery and never heard from the seller again.Very bad service, bad add.Amma Miller704 365 7311
