Lithium batteries are more expensive than their Alkaline equivalents, but perform for a much longer lifespan. In comparison, Zinc batteries last ~ 20 times shorter, Alkaline ~ 8-10 times shorter.
Furthermore, Lithium Batteries hold on to their full voltage to almost the end of their charge life, while alkaline batteries decrease their voltage output throughout their performance.
Therefore, to have a device that works best and lasts a long time, we recommend that you only use Lithium batteries
