What size battery does it use and how long does the battery last?

Mine uses 1 D-battery. I used it a few times last summer, but haven't put it out in the sunroom yet this season. The battery never died last summer with intermittent use (mostly on weekends when the family was out by the pool).

2 "D" cell batteries that will last 3 to 4 days with continuous use (24x7) and 4 to 6 months with intermittent use.

1 D size battery in the model I have. The battery lasted all summer with intermittent use.

It is an about nickel sized battery, readily available at Batteries Plus and similar stores. You can get the number off the one that comes in it.

I have used it a couple of times, the battery lasted about 6 hours the first time, once I charged it fully it lasted about 12 hours and I haven't charged yet since. hope that helps.

I have been happy with it. Instead of about 2 hours of unplugged life, the battery gives 3 hours. The physical size is the same.

Its small round flat battery (3/4 inch diameter about the size of a quarter) that is supplied with the scale (not a typical AA or AAA type battery). We have had the scale for about a year and haven't had to replace it.

Not long. 20-30 minutes max. Mine came with an extra battery, which makes it use able. You always have to have a spare charged. Other than battery life, it works great.

From what I am seeing online, you can keep it plugged in to last longer (charge it). It lasts for about 15 minutes when fully charged and lasts for a long, long time (no real time table for the battery though). Can be a year, can be 5 years depending on usage.

6-8 hours. It lasts a few days, but I don't suggest this for heavier toddlers. My 2 year old is 45 pounds, and this thing barely moves. Certainly not what I expected. I wish I would have gotten something similar but with a bigger battery.

Same as the other two responses, I have never used it long enough at one time to find out. I rarely have to change batteries though.

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.

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

The device takes a standard 9 volt battery. I have no idea how long the battery will last. Mine is still going strong. My in laws have a couple of unruly Dogs that jump all over the furniture and me. I quietly pointed this thing at the Dogs and they recoil and stay well clear of me. I have only had to use it four or five times. They stay away, and it stays in my pocket. No one knows I have it. It may or may not work for you. For me, it has done what I wanted/expected.

I don't recall what battery it uses as it only worked a couple of times despite replacing the battery, so I got rid of it. What can one expect from something so inexpensive while still making a profit off it? It was cheap in price and cheaper in actuality. Don't bother getting it.

Hi. The battery Will run for about 5+ hours if you are using the power saver configuration and you are just browsing or using Word. Any heavy use (vídeos, streaming, large databases, etc) and the battery Will last for about 3 hours.
