does the display run off of batteries?

Nothing on this treadmill runs on batteries. It receives all its power from the wall. I love this thing.

No, not completely. At least not that I'm aware of. When it's been idle for a little while, it goes into a standby mode where it displays BC 5.12 (the model number) and the current time.

It does not, but the batteries last at least a year. If you decide on this monitor you will love it. I would not want to be without it, no more surprise guest!

The unit does not sleep, the display stays on/lit until you turn it off yourself! I would class this as a regular LED display you would find on home appliances? It isn't particularly bright, but not overly dim either. In a well lit room it is quite unobtrusive, but clear and visible in the dark. The Amazon picture is a fair depiction of what you get!

Well, it does seem to use a lot of battery power. Requires 4 AA, I believe. If you exercise regularly, the batteries have to be replaced every few weeks. The milaege/calories display does not "glow" and it is difficult to read the display, regardless. Less than adequate, I would judge.

There is a button to turn the display on and off... If you can actually get a display that works properly.

Yes, the monitor has a rechargeable battery (doesn't last very long) and an AC adapter.

No. The unit requires 3 batteries for the LCD display. It does not have the power cord option.

It does not. I just confirmed it with the one I just got - unplugged it - pushed the power button - nothing. Nice display though. The rechargeable battery seemed like a weak feature anyway because it was only rated at ~1-hour of use.

It takes a small button battery type LR44. It even has a power switch where you can turn the display off and on so, if you wish, you can turn it off to conserve battery life.

Display shuts off automatically after a certain length of time. There is no on/off switch.

Unless you're using the device full time and you have the display at max brightness the battery lasts for several days. On standby mine has gone 2 1/2 weeks before going to below 10% power. Hope this helps.

It has auto turnoff as others have said. The battery will probably outlast the calculator.

It is not possible to turn off the display at any time, though you can adjust brightness from 0-100. The best technique to use to conserve battery life is turn the unit off when not in use. This only takes a second or so.

The display doesn't stay lit,I use the batteries so not sure if it is plugged in if that makes a difference.

There's nothing on the display when not in use. HOWEVER it does blink when turned on and measuring. Not that this is the black LCD readout panel. No blinky lights.
