MacBook Pro battery replacement

 

I am still using hand me down MacBook Pro PCs from 2010. I've replaced the internal batteries once before and it needed a replacement again. Luckily, I found the original seller on the internet where I purchased from before and the price was still very cheap. It included the necessary tools for replacement, and I watched an IFixit video for a detailed explanation. The last battery lasted for about 5 years so I think My MacBook will be beyond end of life by then!
