Not very long at all. That's actually one of my complaints. Mine shuts off in less than 30 seconds...

It needs to be turned on and off manually. I have left it on for about an hour, but it didn't auto off.

I don't know! I think it goes off automatically after sitting for a while, but I don't know of a button to do it.

Yes, it automatically turns itself on and off. I have been very pleased with this unit.

You can turn it off by pushing the button until it says off, and again until it says auto so it still functions on the timer. Same for on.

It will automatically turn off after 1 hour. AFAIK you can't change this behavior but you can extend it to two hours if you set 2 alarms, one hour apart from each other.

From the time you turn it on, it takes 5 seconds to tare out to 0.000. Then you have 1 min before auto shut off. (if you are not touching it in any way).

It does automatically shut off after a certain amount of time, the longest time setting is 1 hour.

This device turns off automatically after 20 minutes at rest (parked) by default. There may also be an option to have it turn on automatically, but I do not recall.

About a year for me. It turns off automatically after 24 hours then turns on again when it senses movement. Not so long if you keep it in the truck as the constant movement keeps it on.

Though I manually turn mine off to make the battery last as long as possible; the manual indicates it turns itself off after 10-15 minutes of inactivity. I consider that to be both good and bad. It's good if you're forgetful - it's bad if you want to closely monitor something longer than some preset time limit.

It turns off automatically after about 30 seconds, unless there's motion. When there's motion, it remains illuminated; turning off after 30 motion free seconds.

My version B turns off automatically when not in use, is that what you are talking about? I think it waits like 5-10 minutes. I rather like this feature.You should contact Amazon directly about your replacement questions.

No. You have to manually turn it on it will automatically turn off once it has finished its cycle.

It auto shuts off in about 4.5 min from last use. Odd number but I verified it 3 times.

I hold the off button for 4 to 5 seconds and then it turns off, I never hear it again. :)

Sorry it took so long, I've been away from it. It has a 2-hour auto shut off.
