Umm... Googled and found this:

It should help

Thank you - but this is no compatible modell - it has to
be the one stated above. (Dell Vostro 3750 or compatible)

Each battery has usually: +, -, data, controll = 4 pins

Each laptop manufacturer has his own pin assignment,
but this can even be different for each laptop model.

We sell an external battery charger for laptop batteries.
If I would have a battery on stock, I could easily find
the pins - and now I have a request for a bigger quantity
and dont know the pin assignment for above Dell model.

Manufacturer of charger doesnt know, Dell doesnt know ....

Looks like I have to buy one battery to test it ... or
one of you can help.

Ok, case is solved


the customer has organised Dell to send me a battery that I can
test our external laptop battery charger with this specific battery.
