What is the difference between a Li-ION battery and a Alkaline battery?Updated 9 months ago

Li-ION maintains its voltage over time until software enters and turns off the power so as not to damage the cells. Then the lamp goes out. This means that you get a very even flow of light from the lamp with almost as much lumen all the time as it gases fully all the time. The disadvantage is that the battery life will be shorter. 

Alkaline batteries lose voltage all the time and have no built-in protective circuit that goes in and cuts. They gas as much as they can all the time, but as the voltage is constantly going down, so too is the light going down in strength all the time. Advantage is that you get a long battery life. Disadvantage is that you do not get as much light as with Li-ION.
