Kowalski 620 torch

[Mike_Kiev]

Hello.
My friend gives me an old Kowalski 620 torch with a charger. He knows nothing about it)
Here like charging contacts looks like. Bit which is "+" and "-" here? Because charging cables didn`t have "+" and "-" marks too and they are similar.
Thank you in advance

I'm quite sure that these 2 "banana terminals" of the charger may be connected "either way".

in Electronics, any well-known brand either makes connections "fool proof" , or makes the internal circuitry "fool proof". That european brand, for sure, choosed the second option with a "diode bridge" inside.

Hope the Battery is still in working condition.

Thank you, I think the same, because any marks on both "banana connectors ". But can't find nothing about it in internet.
Battery still works)
