My Advice

The iFixit online instructions and the battery toolkit with pentalobe and Philips screwdrivers and blue plastic prier tool makes this work for newbies. The only touchy part is properly seeting the battery connector to the socket. Be patient and careful not to press too hard and bend delicate prongs.
