Any battery (Not Included) may leak caustic solutions or gases which can corrode the inside of your flashlights. You should remove the batteries at least a month and visually inspect the inside of the flashlights for signs of corrosion. If your flashlights are used infrequently, e.g., once a month or less, it is recommend to remove the batteries and store them separately. This helps guard against corrosion and may also prolong batteries life.
