Teardown

Einleitung

This teardown shows a complete disassembly of the rechargeable battery for the MacBook Core 2 Duo. This teardown shows how it's put together and all of the components that make up the battery.

    • The metal bottom plate has some glue on it around the connector end. The opposite end can be lifted to help break it loose; it fits straight down.

    • Note the built in slots to hold the connector cards on the end.

    • The interior holds six battery packs; three stacks of two.

    • Here you can see the stacks.

    • Here you can see the two connector boards.

    • The white paste looking stuff is where the battery pack broke open and leaked.

    The white stuff is not leakage, it's adhesive.

For anyone who might need to know…

The pinouts on the aftermarket battery I have are labelled as follows…

P-, T, D, C, /, P+ This is reading right to left, holding the battery in front of you, right way up, with the pins facing towards you.

I interpret this to be, Power minus, Thermistor, Data, Clock, Switch, Power plus respectively.

The P- is connected directly to the negative of the battery. The P+ is not directly connected to the battery, but is connected via a solid state switch on the battery PC board.

The "white paste looking stuff" is not a from a ruptured battery.

There's pictures of other batteries with it, mine has it, it is normal - probably an afterthough to stop wiring going astray or shorting out.

Anyone have the schematic for the lipo cells connection?

I have a question about this batter & im hoping someone will let me know if it’s a bad one so I can avoid damage lol.

anyway here it is: I dropped water on an old macbook I had completely rewinding the motherboard. This happened years ago and I know there’s no salvaging the computer itself but right before the accident happened, I had sent it out to Apple for warranty repair (unrelated to the batter) and they swapped my battery for a brand new one. So anyway I have a brand new batter and I’m wondering if I can use it as a power source for some LED light I have. I didn’t know the controller was inside until I opened the battery up. Anyway now I’m thinking that if I can (I hope I can) I’d like to see how I would go about drawing power from it as well as charging it without having to put it onto a computer. Help anyone?

They are normal 3.7v li-ion polymer cells. Probably 2px3s (2 in parallel, 3 in series) So you could use them for lighting leds. There are hundreds of chargers/chargerboards for these kind of batteries on AliExpress or Ebay but you’ll probably need to do some soldering.

And of cause you need a driver for the leds if there is not already one included.

Maybe you can sell the battery. There are a lot of MacBooks with bad batteries out there ;)
