You have to unplug it when you turn off the engine or the car battery will be drained, but when the engine was running, it never quit even on long trips.

I have run mine (a VW TDI diesel with an 80Ahr battery), about 8 hours with no apparent ill effects. But I never measured battery voltages or did any tests with data or measurements so I don't really know the maximum, or how much it depends on external temperatures, etc.

It's stayed charged in my briefcase for a couple months. But, I wouldn't recommend keeping anything with a battery in a car, if it may be exposed to very high temperatures. Just like anything, it could melt - or worse, combust. It is a battery, after all.

Not sure. I used it on/off for 4 hours. It last longer than my cell phone battery used as the music source.

It usually last for 2 hours. You should be able to get a second Battery, even a bigger one.

I had it running over 2 hours on a car drive once and it still was holding a charge. It got very hot towards the end. Hope that helps.

I have the Nano but I dont use it for a radio connection in my car or outside of my car. The battery without being plugged in to a vehicle lasts for around 6-8 hours depending on how much the battery has been used before you purchased it.

Hi, I have not used it that long, but so far, the battery is holding up. Have not tested it on an all day run!Sorry I can't be of more help!

It lasts a good while. I have a large yard and only need to switch to the other battery for the last quarter of the yard. I have never run down both batteries if they were fully charged when I began.

i have not yet used this backup battery since installation. but im sure it should last more than a year unless your car is consistently being ran out of battery and forcing your alarm to use its backup battery.

I found the battery will last about 1 year. I have had to replace it 2x since I have owned it. the total hours/miles have not reset on me.

it lasts as long as you dont use it. the battery does not lose its charge once it is charged

I bought the car in January- the battery was fully charged and I still haven't charged it at all! My kids don't drive it everyday but it does get used about 3 times per week for about 20 minutes at a time. I read that over charging the battery tends to cause problems so I've been waiting for it to run out before I recharge it. I'm totally shocked at how long it's lasted.

No, I think it is good for a max of 8 hours or it will kill your car battery. I generally unplug it when I go away from the car for more than an hour. I will not warm up that much over a period of several hours. This is my second one and I love them.

I have been amazed at how long the battery actually lasts. I use mine for Children's Church once a week on Sundays. I can go over a month before I have to charge it again.

After it's fully charged it last awhile. The longest I've had mine on was 1hr 30 mins

It is good for 5 hours or more. When you tap the button on the ear piece bar and say battery, it will tell how much time you have left.

The charge depends on how hard you run the car. My 12 old son runs it pretty hard continuously and the charge last 20 to 30 minute. To charge it up again takes a few hours. He has two batteries for his.
