18V Charger Replacement

[vidarr]

The charging "station" for my drills broke. While I am waiting for the replacement parts to arrive, I need a quick fix, so I don't lose work. There are a lot of videos online about using a laptop charger/psu to charge 18V tool batteries. This is far from ideal, I know. My question is, of the four outputs of the charger (original), which two are the power supply? My first guess was the Red and Black, but then I was thinking maybe it is the Red and Green.

If the charger was working, or the batteries had any charge, I could figure this out easy enough. I looked up the pinout for the charger and cannot find anything. So, can someone help me determine which two outputs of the charger (inputs of the batteries) are the positive and negative?

Thank You!

Here are a couple extra pics.

If you plug in the battery you should be able to measure the voltage on the according cables.
If there is not a single Volt left in your battery pack, you have an additional problem.
Nevertheless I would assume red+ black- green,yellow temperature sensor and maybe some coding of voltage or capacity

What brand is it? That would help finding someone who can help – e.g. by quickly measuring their own battery.
