Reliability of batteries and their damage to equipment

[CoogarXR]

I have had 4 of my Mag-Lite flashlights ruined by duracell batteries. The Mag-Lite + swelled battery combo has been well griped about all over the 'net. There is such a small gap between the batteries and the side wall, when they swell the least bit, they get stuck. If they swell alot, they get VERY stuck, heh. I have had to drill a hole through the batteries, and make a corkscrew out of a thick coat hanger and thread it through the battery and pull like a slide hammer until it comes out. All of these batteries swelled before they were totally dead. The flashlights still lit, just kinda dim. These weren't just drawer flashlights either, these were flashlights I used daily for work. Something has definitely changed where these batteries swell and leak before they are even dead!
