a1496 battery pinout ples
It is the System Present pin. Once it is connected to GND the battery chip know it is inserted to the laptop motherboard, then the chip goes into Normal where Charging/Discharging are allowed.
hello all ,
i may be the only person who has not been able to use this nlba ..everytime i try using it i get frustrated and give up . ended up just tearing all batteries and pulled the cells . anyways reason i am here is i have a A1466 laptop with A1494 battery . i have tried the suggested pins and still no readout .
1. what does the Connectors : 2 mean in the laptop model battery pinout .
2. does anyone have pinout for A1494 ?
Why don't you try first a more simple good battery that use no System Present to get familiar with the device ?
This Apple Battery uses System Present and if it is over discharged then you need to press Power On button to read it.
In order to identify the battery pinout you can use the method described into Chapter 7: https://www.laptopu.ro/Download/Manual/Manual_NLBA.pdf by checking the zener diode.
Apple MacBook Air Battery model A1494
Battery Connector showing pins: V1, V2, V3, V4, C5, D6, T7, G8, G9, G10, G11
1 to V
5 to C
6 to D
1+7 to G
Pulled PCB from A1175 bulged battery:
Some silk prints seen there:
"Apple PW1 Rev A"
"+TDCN+" - pinout, BTW.
Lets Make NLBA Great ! Together.
This doesn't work for me, also the pinout showed in the application doesn't work! What am I missing ?
This is definetely NOT the correct pinout!
Check the database
You have 4 wires for + and 4 wires for - on the left and right side of the connector. The middle 3 wires are Clock Data & SYS.
Im working on a bunch of A2113 batteries. Which are made by apple. And they have the Charging boards inside the laptop. Like pictured. I have found Pin 2 is the data, pin 3 is Clock, Pin 4 Might be a ground to activate the battery ( I havnt been able to test this cause my current connection method would require three people to hold 5 probes and run the computer) so its not locked and will allow charging. and then pin 5 is negative, and pin 6 is positive as labeled. Pin 5 and 6 are beside each other and are marked positive and negative.
Does anyone know for sure if pin 4 a system preset pin?
And what has everyone done to help make connecting to these test spots easier. And a one man test?
Has anyone made a tool or a mocked up pcb break out board with contacts in it? It even a breakout box that has a ribbon cable that would plug into the data and clock ribbon cable connection. I'm dieing trying to find a easier method to connect and revive these batteries.
They have only been sitting for alittle longer then 6 months, they were never really used. And theres 8 of them that wont charge anymore. Even did the SMC reset.
Any help would be greatly appreciated.
