No..it won't be the end of the world and your car will not explode, but it also depends on your car. If you remove your existing battery without looping in an extra 12v battery the settings of your car will get reset. In most average cars this resetting will be as simple as the clock losing its time or the radio losing its programmed radio stations. However in some, mostly modern and some high end older, cars; it may lose settings for things like its security system/immobilizer and even various control systems if the battery is left disconnected long enough. This will make the car unusable and require it to be taken to the agent/specialist-garage on a carrier or have them come to you to reset and reinitialize everything.
