what size is the battery and how long will it last

The information provided for this Laser clearly indicates that it is Charged by 1 x CR123 3V Lithium Battery (Included). My Laser came with a Rechargeable Battery so do not know how long it lasts because I do not allow for the battery to fully discharge. I purchased an additional Rechargeable Battery so always have one battery in use and one fully charged in my pocket.

That completely depends on the speed you are running it. If you only run it at full speed, it may last two hours on a charged battery. If you run at the lowest speed, it can last up to 15 hours or so.

Pretty long. Months I would say. We got ours about 10 months ago and I think I have only replaced the batteries 2 or 3 times. Pretty good considering it is used almost every night.

I'm not sure about the battery life. But I haven't changed battery yet since I bought mine. Just be sure to turn it off after you use it.

I am not sure of exactly how long but it seems to be about 2 hours or so. I have actually never timed it. This is an older laptop my kids use for games so that might be why the battery doesn't seem to last very long. Hope this helps! :)

It is a rechargable battery that lasts about 2.5 hours. You can also plug it into a wall outlet and use it while it charges

It will run about 10-15 minutes with the battery that comes with it. With a more powerful battery it will run close to a half hour.

It has roughly the capacity of a laptop battery. I don't know your exact laptop model, but I would expect that it would last about as long as with its built-in battery.

About a half an inch. Don't go by the physical size. There are other batteries of the same size. Find out what you actually need.

Its big. Like maybe 6-8 inches long and it needs batteries which came with it. I was surprised as to how big it was. I love it!

The battery will last for 10 hours, but only when kept at a moderate volume. If you crank the volume up near max, the battery will last about 5 hours.

There's nothing in the instructions that say how long the battery will last but mine only lasted a few months.

Brand new with average use it will last more than 20 hours. Do not make the mistake of overcharging the battery. Disconnect right after it is fully charged. The battery will start dying faster which happened to me.

It is 3" long and 1 3/4" Wide. It is very small. Uses a AAA battery. Very responsive.

It depends on how often you will use it . If used a lot i don't think the battery will last for several days.
