Thank you for the tutorial. It helped me to take the swollen battery of my MacBook Pro out. Am now looking for a reliable new battery, would be happy to buy the iFixit battery listed on this page. However, my MacBook Pro (13” Unibody Mid 2012) was purchased in Asia (India) and works on a voltage of 220–240V. Will the iFixit battery work with that voltage? Would appreciate any response. Thanks in advance.
