Alright lads, I lost the lottery on a 72wh battery for my t480 that I bought off of Amazon. Two weeks in and its down to 75% capacity. It's certainly not unusable like this but it hurts my 'tism. From what I've read Kingsener seems to be the recommended brand for older thinkpads. Is this correct or is it just shilling? Newegg has one listed for a reasonable price.
