How long does the battery last on this thing?
1785651
I was able to use it on a 12 hour flight and around an hour driving connecting via bluetooth to a single device without recharging. 10 hours is a good estimate if you keep the lcd light setting on "momentary on" (where it lights for about 5 secs after pressing the power switch) but it could probably go longer. Its only drawback, although a very minor one is that the charging port in this model is the usb-a type, not usb-b which is used in a lot of smartphones today so you might have to bring multiple wires üEdit: lasted around 18 hours this time. A near 14 hour flight, turned it off for 2 days, no recharge and around 6 hours before battery finally quit I was able to use it on a 12 hour flight and around an hour driving connecting via bluetooth to a single device without recharging. 10 hours is a good estimate if you keep the lcd light setting on "momentary on" (where it lights for about 5 secs after pressing the power switch) but it could probably go longer.

What type battery, I've ordered the unit but would like to order an extra battery

Battery life of up to 16 hours is claimed, so you can count on at least 12+ hours of continuous use.Note that the new Bad Elf Plus (Pro) will soon be available too.It adds Barometric Sensor, Thermometer,UPS File Support, and Streaming NMEA GPS Output.Handy for a pilot, but not too useful for the typical iPad user.

Mine has stayed on and functioning for over six hours. Have yet to run it down.

I have used mine on 4 consecutive flights of between 7 and 8 hours each. It still had 1 bar left on the battery level indicator after the fourth sector.

I don't know exactly, but have had it on constantly for more than 12 hours at a time without charging

Battery life is pretty good... A whole day if your actually using it.. I've left it sitting and it's lasted around 3 weeks without usage on one charge.

I still average about 2-3 hours on mine. I've had in the neighborhood of 15 months. Been a great battery.

It actually has it's own built in battery. It lasts about 5-6 hours, which isn't too shabby.

I've had mine for 2 years and it seems to be going strong. The battery charge doesn't last a long time (about 15 min or so) but that has always been the case.

I haven't done a test (like running movies for hours to clock the battery life), but I would say about 6-7 hours of use. I use it a lot, but only need to charge the battery every 2 days or so. No battery gets used when it's off, either (I know that sounds silly) - for example, I had charged it fully and the. Had it in my bag for 3 days before taking it out to use it, an the battery was still charged to 100%. So far, great battery life. Hope that helps.

I don't know the life span of the battery. I still have the same one that came with it when I bought it back in December. Maybe someone who has had one of these longer could give you a better idea about the battery life.

My battery last for a while. About 2-3 months, but I think it depends on how much it has to be used. The batteries are cheap at Walmart.

I use it on the bus to work, my commute is short about 45 min.; the battery last for about 4 days. After using the on, off, volume up/down etc. for a period of time, the printed data dissolve.

Around 1 month, and I use it daily. Howere, sometimes, the led light in front keep flashing, then the battery will last for a couple of days only.

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

Battery - guess it depends on how much you use it. Sorry I can't be more specific

Yep. It has a built in rechargeable battery that lasts up to 10 hrs, though I've actually gone longer than that on it.

depends on your weight. 3 or 4 hours for me when batteries were new, but unit is cheaply made and doesn't last long.

the battery life lasts approx 4-8 hours...sometimes longer if not used continuously.

I don't have a definite answer for you- but I can say that we took it on a 5.5 hour flight using it on and off throughout the flight and the battery lasted the whole time.

A few hours (I haven't clocked it), I think. I've watched a movie and then a tv show afterward. The cool thing is that you can plug it in to charge while you're using it, so that works great!
