Connecting coaxial power connector to the battery

[bulduzer00]

Hello, I want to have my battery as a main power source so I can plug it in to my device which have this coaxial power connector(outside using). Everything I need is to cut this EU Plug split the wires and connect to the battery, which one is the positive and negative wire?

It should be noted on the device it plugs in to.
