I have own my Mag Charger for about 15 year . I be a mechanic so it see constant use for the first 10 of those year . it be endure abuse beyond belief . countless drop onto concrete . I once drop it from the top of a cab-over tractor . it burn out the bulb and that be all . after year and year of use it be begin to get dim . yeah that be right the original battery pack last till just a month ago . one of the cell finally die . the rubber seal on the switch have go crunchy after the year of exposure to brake cleaner and who know what . I order a new nihm battery from Amazon but could not find the correct rubber button . -lrb- Mine be the old style -rrb- I call Maglite . remember these baby be guarantee forever . that include the rubber part . mag send I a new button no charge . yeah that be it , not only be it the best flashlight in the world it be back by a real no b lifetime warranty by a no b company . you may find light that have more lumen or cost less . they be not worth it . this dude be ready for the long haul . if you be ready for a no b light then you be ready for a Mag Recharger . it will last and if it ever break Maglite will make it right .
