I purchased this lantern a VERY long time ago (more than 4 years ago...I think...I can't remember anymore) and have yet to have to replace the batteries in it. I live in an area where we are prone to lose power from storms and tornadoes. I use it a lot and it performs very well each time. I am considering buying 2 more so that I can have one in the basement and one in my office. They are well worth the investment!
