We go through uite a fređbatteries in a short matter of time. Several of our remotes and other devices need AAA batteries and I never seem to have them on hand when I need them. I like that this box comes with 28 batteries as that will last a couple of months minimums. I like that these batteries have a 10-year shelf life. I have not had any leaking or deterioration of any kind with these batteries that we have used.
