About eight hours
it take an duracell battery in a flashlight non-stop lasts exactly 15 hours
This depends on the working conditions.
That's going to depend on how often, and for how long, the flashlight is turned on.
Duracell
It depends entirely on the discharge current. If you require an accurate answer you should contact Duracell and request technical assistance.
No set answer to that, it depends on the size/capacity of the battery and what it's powering.
duracell obv.
Depends which size of battery, what you are powering with it (motors take more power than radios), and which grade of battery you are using.
