No set answer to that, it depends on the size/capacity of the batteries and what they're powering.
About a year or two. Or maybe three.
Which brand of AA batteries lasts the longest
15 hours....................
i depends on the toy
Duracell rechargeable batteries are reliable, but like any brand of batteries, the life will depend on how the batteries are used, maintained, and stored. Rechargeable batteries do not have as long a shelf life as most other batteries, so they do have to be maintained. With proper care the Duracell rechargeable batteries will give you many hours of camera use, but it is always wise to carry extras.
On average duracell plus (AA) batteries last for about 3 hours in a remote controlled car if it is moving for the whole three hours. Hope this helps
Rechargable batteries will not last as long as normal AA's, but, of course, can be recharged, and should last over a year.
In my personal experience, they have always lasted longer that Energizer and other brands I have tried. They use Duracell batteries in the transplant of artificial organs simply because they are known for their lasting duration.

No set answer to that, it depends on the power consumption of what they're connected to.

That's going to depend on how often, and for how long, the flashlight is turned on.
