If you use some 1" schedule 40 pvc pipe as a sleeve it can be done permanently. In my "5D" maglite I cut a sleeve and it now uses "6C" batteries to overdrive the stock bulb making it brighter. I only had to slightly stretch the tail spring for better contact. In my "3D" maglite I use "4C" by using a sleeve and flipping the tail spring upside down. D-cells cost 2X C-cell batteries

According to a Popular Science article a while back, they found very little difference between the cheap batteries and the name brand for basic useage. You can go to the Dollar Store or your local Wal-Mart or Fred Meyer and get some cheap but useful batteries.

I did the tests myself, and the real ones last 40x longer

[thoraxe]

yeah, anyone will notice good quality Duracell or energizer works way better than dollar store batteries

In Britain the Pound-shop AA's last for about 10 minutes in a gameboy advance. Don't know about america, but that doesn't apply where I live.

[mettaurlover]

... what type of batteries were those? i mean, what brand?

[themeatloaf]

NOTE to US readers: Pound-Shop is like Dollar Tree or $1 or Less in the US.

[baneat]

Sort of, A pound is almost twice as much as a dollar, but you get the point.

[Redgerr]

same difference though :P

[themeatloaf]

No spare Cs, but yes foil, It can be used if I blow a fuse.

Aww, videos are cheating! They're hard to skim, hard to browse at work, and hard to print. Not that I've ever printed an instructable, I'm just sayin'. Videos are a nice help for things like knot-tying that are just hard to do with pictures, but I think this should really be a plain old series of pictures.

[tomonto]

why would you have a sheet of tin foil with you but not batteries?

[themeatloaf]

As I said in the video you can use coins or washers. I have Duck Tape and foil in my car.
