well you could pick up a spare battery just in case it runs out. You can't run the a/c without powering on the car and the car power recharges battery but really wastes gas... Alternatively you could invest in a portable thing that has headphones... used to be walkmans now the thing is ipods or zune or something. That way your transportation is safe.

Check how much charge your battery holds. Then see if you can find out the minimum voltage needed for the starter to crank. After that, see if you can find out the consumption per hour of all your stereo equipment put together. Then just do that math and find out how much time you have. You can also skip the last few steps, and just find out the minimum cranking voltage for your starter and install a volt gauge that will measure how much charge is left on your battery.

You can leave your radio on all night and probably not drain your battery very much. Your CD player uses more juice because it has to turn the motor that spins the CD.I only play mine while I am driving. The radio, I'll play it without worry.Best Wishes.

you can always install a very expensive deep cycle car battery. it can hold charge for about 2 hours running everything from headlights to radio with the car off. optima batteries do just such. The YellowTop deep cycle capabilities allow you to amp it up longer and drain your battery deeper than traditional batteries. It also provides cleaner power with higher voltage output and 16X more vibration resistance than traditional batteries so your battery can bounce to the beat and not lose power over time. Its leakproof design allows you to mount it anywhere, in any position.

Default Re: How long can I listen to music while engine off before car battery dies ?

I bought a 2007 Honda CRV and drove it off the lot this morning.

Right after picking it up I drove around 15km to a beach to put my stuff in the car. Ran the music with the engine off for approx. 10 - 15 and it was dead .... I mean dead, not a peep or sound.

Dealer came and gave me a boost and said that I can't run my radio with the engine off.

I think that is absolutely ridiculous bunk. Never heard of such a stupid thing.
So you go to the beach and want to watch the sun go down and you have to keep your car running to get sound?!?!!?

People would sling mud at you or worse for idling.

Can this be true? If so, I don't want the flipping thing. I drive and sit a lot with radio or cd going.

I want them to put in a new battery ..... not very good for the first hour of owning a vehicle!!!

ps: He says that everything runs, ie: navigation etc in the background even when it has been turned off and/or not in use. Is this true?

When I get to work I listen to the aftermarket CD player for about 15 min before i leave the car to go to work and I have never had trouble.
