Sun Safe Cr123's ?

[Boy SureFire]

With the recent outbreak battery related explosions, Is it safe to belt holster and EDC my stock Cr123 flashlights (surefire 6p, E1e, E1e) if I'm out in direct 95+ degree sunlight. I like to left-side carry since it's my weak-side, and carry my knife, tac pen, keys w/ leatherman micra, on the right-side. I generally spend from 9-11:30 AM with my left-side in direct sunshine, I'm almost certain that by 10ish it's already 85+ degrees. I picket @ a clinic w/almost no shade so it's important that I know it's safe. I've also read here on CPM of batteries in storage going BOOM, so please help me soon, lest I go Kaboom.

......Also let's try to keep this to being about batteries, since I don't want this thread to get closed before I know for certain.:thumbsup:

After you've done a full shift in the sun, hold the light in your hand - if you can hold the flashlight, then it's not too hot, and the batteries will be fine. 123s are comfortable out to about 140F, which is about the temp that your hand can't tolerate.

Sweet thanks for the fast answer :twothumbs
P.S. the lights are warm but not hot.
P.P.S. you may start going off topic now that I know the answer

I keep 123-cell powered flashlights in each of my five cars and they sit out in the sun on occasion (four are garaged, the fifth is always outside), and I can guarantee you the lights in my cars with black interiors in direct sunlight see higher temps than what lights will on your belt (unless someone sets you on fire). No problems that I can see, but I only use Surefire cells for applications like this.

My car sits out in the sun all day, if there is sun that is, but on hot sunny days, my car gets up to 55 Celius/131 Fahrenheit, inside.
In the glove compartment is my HDS EDC 42 and it never went boom.

What does make cells angry is short circuiting them (putting them in a box with screws, nuts etc can make them short out, so always store your batteries neatly in a dedicated box, in such a fashion it's not possible to short them) or using one empty and one full battery in your flashlight and then emptying the battery in a mere 20 minutes, with it heating the flashlight and the battery. That is often enough.
There is some sense in the phrase on the batteries which says: don't mix old & news.

Lithiums hold a lot of power in a small package and it is able to release that power in a very short time. That's why they can become dangerous if handled unwise.

Update, I gave the 6P away and now my E1L is in its place:thumbsup: Yeah love SF E's since they're so freaking easy to carry. On an unrelated note, I'm shocked that a big argument hasn't started over ... [provocative content deleted - DM51]

Yes, it is unrelated, and I have deleted it. You must be very disappointed that CPF members did not respond to your deliberately provocative baiting, which has earned you a 4-day suspension. Please use the time to read the Rules, taking especially careful note of #4.
