How does the battery works???

It lasts forever, if that's what you are asking! Plus, mine came with an extra battery that I keep charged just in case. But I do extensive emailing on it and I can wrote two LOOONG emails before it even drops below 20%...like 6 hours of constant use at the very least. And I use a Swype keyboard which seems to use more power than the simple android keyboard.

Gee I bought it awhile ago now and it plugs into an outlet, but I checked the description on Amazon and it doesn't say there's a backup battery. There is a little red light though, so if it were to turn off, you'd know it is not working.

I got this for my son last year. About 4 months ago the battery quit holding a charge. For a time it quit turning on and somehow my husband rebooted it and got it going again (sorry, I don't remember how they did it). It works as long as it's plugged in.

Well it's not technically a battery. It holds up to two batteries in it so your battery life is now doubled. It's well worth the purchase!

The battery is rechargeable and built in. There is a hole in the device, under a small rubber cap, where you plug in the cord to recharge.

It comes with its own battery that you have to charge. The battery lasts a LONG time and charges fast.

It has been a while since installed it but it uses a mall backup battery which I did test. I forget how that I tested it.

Regular batteries work - I think they're AAA. Only two & they last for a while! From what I know - rechargeable batteries and regular batteries work the same way - it's just that the regular ones are discarded after they loose their charge.

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 works fine on the battery. Last a long time as well. You do not need to plug it in to make it work if the battery is charged.

As far as I can tell, the battery is internal. It requires a cord to charge it, which is included with the purchase. Hope this helps!

It actually works off you. You turn the wheel which generates whatever power is needed. There are 2 AA battery's for the display (memory retention I believe).

The battery was dead when i got it. It recommends u charge it before using it. I never had any problems with it. Once i charged it initially it was fine.

Believe it uses a lithium ion battery that holds a pretty long charge on it. When the battery is low plug into AC power to restore battery life.

The battery is extended. It should provide almost double the capacity of the original battery.

It takes its own special sized rechargable battery. it is a little larger then a AA battery. The charge on the battery last a long time.

The battery is charged by the USB cable. So it charges, scans and sends the scans to your computer. But the battery should be charged when you first receive the scanner.
