How do you put 4 AA batteries in a Ozark Trail Mini LED Camp Lantern?
Hi, i bought a mini lantern (Ozark Trail-Mini LED Camp Lantern) at Walmart the other day…for out at the lake…..it takes 4 AA batteries but some how i can figure out how to put the batteries in?!…in the bottom of the lantern it unscrews but it looks like it takes 1 big D battery, and there isn’t even like slots for each individual battery?!…can any one help?
Maybe the batteries have to be in a pack together, and that pack plugs into one point.
