What’s Inside a Macbook Pro Battery?

So my Macbook Pro battery was completely shot. It wouldn’t hold a charge no matter how long I kept it plugged in. It was time for a new one. Like a good Apple Store supporter, I made a reservation at the “Genius Bar” to get a new battery and also to upgrade the memory.

The new battery for the laptop was $120! Wow, that seemed like a lot of money for a battery. But upon closer inspection, have you seen a Macbook battery? It’s beautiful all encased in grey plastic with a styling aluminum cover and those blue LED charge level lights. It seemed such a shame to to just throw it away. What’s a gadget guy to do?

Take it apart! I wanted to know what exactly was inside those things. At first I tried to open it gingerly, but then realized it was impossible. The only way to get to the guts was to rip it apart. I was hoping to keep some of the aluminum for ….. something. I don’t know what.

The beautiful and smooth aluminum cover is no more.

After peeling back the cover, I exposed the three Li-on cells in all their glory. It looks like the are using Sony cells for the Macbook. I knew I liked something about the Mac… you see, I love Sony Vaio laptops. In fact I am having withdrawal symptoms from having to use a DELL laptop. I will get a Sony again, maybe for my upcoming birthday.

Oh yeah, the inside of the battery. Here’s the naked picture with all the guts exposed. Now I have to find a way to dispose of this.

Epilogue: After some searching on the web, I found that I could get OEM Macbook Pro batteries for $60, about half of what the Apple store charges for them. Well, they still only last about 2 hours. I can’t figure out why the battery life is so bad. I really can’t use this as my main machine.
