Data pin 6

Clock pin 7

Positive (Voltage) pins 8-10

Usually PinOut is a table of Pins## and its designation; normally people counting pins and use it after the count:

1 Ground [- Vbat]

2 Ground

3 Ground

6 SMData 

7 SMClock

8,9,20 +Vbat

Hi 

Thx mate I know it is like that. 

I wrote for example "Ground pins 1-4" and that means when its dash in between that pins 1, 2, 3, 4 are all ground for sole reason not to write what I just did in  this reply.... . As well as for all of those who are new and more familiar with terms of Positive and Negative 

As proven saving time did not work...lol

Ground pins only 1,2,3 in this Dell battery. Pin 4 is System Present line, it should not be confused with Ground.

It should be connected to Ground EXTERNALLY (for example when inserted in laptop) to allow charging and discharging.

Hi again

1. All Ground, Negative, are the same 

2. So called System present pulls a signal down to ground and that is how the chip knows that the battery is connected - that dose not change a fact that it is still connected to GROUND, NEGATIVE

3. This thread was to inform any potential person who dose not have a pinout and cannot communicate with the battery about what the pinout actually is.

4. this thread has nothing to do with connecting battery to laptop but it has everything to do with communication with the battery using Software provided with the device 

5. if you would like to talk about what is the role of System Present and how dose it work create separate topic or better yet look for one as I'm sure it already exist.

best regards 

Lets fix it!

This area in general is about Pinouts, not only how to connect a battery for communication but for charging and discharging as well. And yes, you posted above Charge and Discharge graphs to prove it.

Ground pins 1-4

The post before was to correct this statement.

On genuine 10pins flat battery pin 4 is not a ground. It is SysPres pin. You could check it with multimeter.

Ground pins are 1,2,3 and 5.

Me have a lot of these type Dell batteries and all they have same pinout.

I never said it is not - I said it is connected to GROUND on the NLBA1 connector and it is!

That is why I do not understand your persistence in this matter.  Frankly it is kind of annoying.

There is no need to check it when you make connection just like I suggested as it works as already proven

Posted by: @djibattworkshop

Ground pins are 1,2,3 and 5

Yes they are and 4 goes to ground as well! 

to be honest if I'm presuming it correctly all you need to connect is 1 ground 4 same to ground 6and 7 as clock and data and 10 as i did not open that battery and I'm not planning to

I do too.

and they are the same pinout as I described above 

 

As I grow tired of explaining to you that we are both right this is my last message as simple help turn out to be a joke 

best regards

Then you simply dont understand the difference between "pinout" and "connection scheme". It's different things by the way.

It was added on the forum long time ago. And there is a rule to search the forum first before requesting a pinout.

How to use "Search" option on the forum.

Enter search phrase, for example "J60J5" in the search field, press Enter. Very easy lol.

Guys, we don't need to go in this direction.

As a personal opinion, Pin4 is officially called System Present by Dell, it is even labeled on the motherboard. It is different than ground, in our database it is labeled as "T". Maybe the customer did not know about the meaning of the Pin4, he observed that only by connecting it to GND the battery was able to charge and discharge.
