Just replaced my battery and after five days it is dead again,.

Hello, either you have a parasitic draw causing your battery to drain after shutting the vehicle off, or you have a charging system issue that isn't letting your battery get back to a full charge again. Or, maybe also you could have installed a battery that isn't working properly. Due to the possible multiple causes, hands on testing is needed to figure it all out.
