I think maglite has a problem with their products because almost everything leaks in them. I run those on NiMH. Only cuz I ended up with a bunch of them, not because I bought any.
I find them to be shitty flashlights anyway because the on-off switch mechanism is dodgy. I hate it. The the ones that have the feature like blinking, triggered by twisting the top, are totally unusable. lets fuck with the flashlight for 30 seconds before we get the mode we want.
I really feel like its a troll brand flashlight. They were like good in the year 2000 because it was bright with the xenon bulb, but today compared to other offerings its dodgy.
And there is some kinda other problem with them too, when they age, even unleaked, the fuckin circuit becomes unreliable. Like the threads. Even if you use silicone grease on the threads its still kinda bullshit. They go dim and you need to bang on it. Its like the horror movie/game flashlight that goes dim every once in a while where you need to tap it. I think thats a great feature for a videogame, so there is a idle animation.
I recommend fenix brand AA flashlights. They don't have too many, but I am impressed. Aluminum head and plastic body, meaning you can leave it in the car in the winter and it does not freeze your hand off. Also they have a twist on that does not suck ass (twist ring switch).
The maglite are ridiculous.
For a work light I recommend the milwakee 2x AA battery side lamp with magnet base (fuckin useful as hell) and for a car flashlight I recommend the 4xAA fenix flashlight if its still sold. Guess not, LD42 is discontinued. I wonder why. I think it must have been the plastic. I thought it was cheap at first but then the first day I needed it when it was -10C I thought it was genius.
