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 ;)
