I thought these batteries couldn't be replaced.
These batteries are built to the same spec as OEM (Apple)
They are just not "user friendly" to replace like most devices are, the price we pay for pretty devices.
This guide is excellent and now I know I need 1 more tool before I do this myself. I need that tri-wing screwdriver.
Clear, well written instructions, thank you! (But yes, a line about take off shoes and socks and ground yourself is helpful. )
