Can you put a volt memter on it to determine positive and negative?
I would think so.
Also, I suspect that there are different Dell batteries. The pin out might be different.

>I am trying to find the pinouts for a Dell laptop battery. Can't find any info on the Dell site. The laptop is having problems charging the battery completely and we want to hook it up to our charging device. Problem is that we can't find any info. Even which is the positive and negative.
