The battery ordered came very quickly, for a praise. I do not know if the pin assignment is standardized on the plug, but in the built-in battery in my old IBM ThinkPad notebook, the ports were occupied at the plug the other way around. On the battery itself, the wires of the known standard as were (red to positive / black to negative) is soldered, but the plug they had just connected the other way around. This is a plug which can be plugged in only one position due to its design.
