the power requirement is 4בAAA’ Alkaline Batteries, and the battery life is 20 Hours Continuous Use with Back Light On. However as the backlight are not always on, especially in the daylight with sunny light, it will be off all along with the operation. Also, people will shut down the unit when they don’t use it. So you could expect to have a very long time for the usual using.
