[gchokeen]

Hello Everyone,

I have mac air MacBook Air (13-inch, 2017), It recently shutdown or goes sleep with in few seconds after power cord is removed, it leads to use laptop always power cord connected. I noticed batter health showing "service" flag.

Some of the questions!

1. Do I need to replace the battery?
2. Is it okay to buy and install on own, If yes where can I buy and what is the suitable battery ?
