PT Rage question

[Brad01]

Another question from the village idiot...
I know the instructions for my Rage don't say I can't use lithium AAA's, but are there any bulb life or thermal issues I shold be aware of?
Thanks!

my pt-40 won't work with lithiums

Brad, lithiums have higher voltage and bulb life will be much shorter.

 

[Brad01]

Thanks Paul.
Do you know approximatly how much shorter or if they will insta-flash on the initial current spike of lithiums?

There was a thread not too long ago that talked about using folded aluminum foil in the bottom of the PT-40 to give a good contact with lithium batteries. I believe the spring may be a little short in some of the older lights when using lithium batteries. I've been using lithium batteries in my PT-40 for awhile. It is bright, light weight, waterproof and rugged.

my pt-40 is a newer model but i don't know what to do to get it to work with lithiums

Jim, was it This thread?
Leukos has aluminum foil with NiMH's...

Brad, I wouldn't expect an insta-flash, but bulb life might be on the order of 3x shorter. This is based on some overdrive formulas from the Welch-Allyn threads and also based on peoples' experience using lithum cells in stock Minimags.

That's the thread...I put a Mag 4 cell bulb in mine with lithium batteries. After that I used the light in some nasty weather conditions. I didn't go out of my way to baby the light, and it came through like a champ.
