Radio Use when engine is not runningYes, use of the radio when the engine is not running will drain the battery. Also, IF the use of the radio requires the ignition switch to be in the ON position, then any other devices [such as on-board computers, electric fuel pumps, etc.] that are turned on when the key is on will also add drain to the battery.IF your vehicle ignition switch has an "accessory" position [usually one "click" counterclockwise from the OFF position, then only the accessories that you turn on, will drain the battery.
If you use the radio without the engine running you will eventually discharge the power from the battery. It should be fine for a couple of hours, If not, your battery may need replacing.
