Does anyone know how long the stock battery should last if it is just powering the radio? I am thinking about taking the family to a drive in this week but I'm not sure if it can handle 3-4 hours of movies. Any input would be greatly appreciated!
You can turn on only the radio simply by pushing the power button on the radio w/o having to turn the key, but it only will play for about 20 mins before automatically turning off. I don't know how long the battery might last, because I can't tell what condition it is in now. But I do know that if you turn the key to use the radio it will draw a lot more juice.
