Mini Maglite AA A battery is corroded and stuck. When I remove the front reflector housing, the plastic cap with the bulb says "Do not remove". Can I remove this cover to be able to push the battery out?

Yes. My Mini Maglite had a corroded battery stuck in it and what I was able to do is remove the bulb cap, remove the bulb, and then remove that plastic part underneath that says "Do Not Remove" (incidentally, the way I removed it is by just pulling it straight out). Once that was out, I was able to push down ******* the part underneath and it then pushed the corroded battery out (I used a screwdriver for this). I had worked on the battery from the other side and maybe that loosened it up but the key point is that it didn't come out until I was able to push from the top and I wasn't able to do that until I removed the "Do Not Remove" part. When you first get that "Do Not Remove" part off, you'll see that the part underneath has a silver metal tab on it; when you push this part in order to push the battery, it may come out the other side with the battery and if it does, this silver metal tab may pop off. In my case, this happened and at first I didn't realize it and so when I put the Mini back together, it wouldn't work. I looked at my other Mini and saw the issue (the metal tab was missing on the one that wouldn't work) and I searched around and fortunately I was able to find the silver metal tab and I was able to put it back where it belonged and have the flashlight start functioning again. So if the metal tab does pop off, it shouldn't be a big deal to put it back where it goes when you're putting the flashlight back together--but just make sure you don't lose it!

Speaking of putting the flashlight back together: I think it will be pretty obvious how you put all this back together but just in case, I'll explain it here. You're going to first need to clean out the inside of the flashlight shaft and remove any corrosion or battery labels that are there. Then you put that part I mentioned above back in; you'll of course need to have that silver metal tab in its proper place. It can be a little tricky to get that part in place but keep working at it and you'll get it. Then you need something to push that part to the top of the tube; I recommend just using the batteries with a little extra pressure from your little finger. Once you have that part held to the top of the tube, take the "Do Not Remove" part and press it back into place. Then put the bulb back in. Then screw the cap back on. Finally, Then screw the bottom back onto the flashlight (you could do this before putting on the "Do Not Remove" part and it would give you good pressure for the part at the top of the tube, but I prefer to use my finger for better pressure) and your flashlight should be working properly!
