123 Battery Shoot Out

Hi Guys, do you know how to get in touch with JSB Jon? I sent him 5 emails for the past week trying to place an order for batteries but never get a reply....! Is there anything wrong with his email?
 
pipesmoker, I have ordered on his site and gotten rapid delivery every time so far. And when I had a problem, Jon immediately fixed the problem and went far beyond what most folks do (sending replacement item without requiring the defective to be returned, etc.)

I have found he sometimes is a little slow about answering email but he is very fast filling orders placed on his shopping site.
 
this is phenomenal info.. i am truly amazed by the caliber of people on cpf...
 
Hello Wayne,

That is an excellent idea. Keeping cells in a group will eliminate some safety concerns.

Thanks for offering this feature.

Tom,
SureFire have been offering this "feature" for many years, well over a decade if I recall correctly. SureFire's SF223AC, SF323AC & SF423AC battery sticks are designed and intended to be protected against heavy recoil for use in WeaponLights.

Wayne,
Do not all USA-manufactured 123A batteries have PTC protection?
 
Hello Al,

Very interesting... When I go to the SureFire web site and put those battery numbers in, I get a reference to weapon lights, but no information on what the sets of batteries cost. Any idea what they charge?

Hi Tom

Using SureFire's website as a source of information?!
Tsk! Tsk!
You should know better! /ubbthreads/images/graemlins/rolleyes.gif

I suggest that you contact a CPF Supporting SureFire Dealer, or call SureFire themselves.

Best regards,

Al
 
At 1.5 amps those surefiires get hot i cut off at 150degrees.

anyway I did this test cooling with a fan durring one test and not cooling on the other. more current on the hot one is produced.
I was wondering on those charts that ou generate on with the cba do you add the wat hours numbers or is there a way for me to get the software to put that there for me?

Hello Yaesumofo,

Higher temperatures give more power, but when things get too hot you can have other problems.

The current CBA software does not give Watt Hours... I am still working on them to add that feature. /ubbthreads/images/graemlins/smile.gif

Just read this thread in detail and that is exactly what happened to my sister using the Surefire batteries I supplied her with an E2. Not once, not twice, but three times from a single box of 12. Light worked fine, next time she used it completely dead without the faintest of amber glow. Wish I had saved the batteries for analysis, particularly to find out if it happened to both cells in the light or just one of the two.

Now I use and give to family members the Sanyos which I get for a dollar each. Thus far they have seemed pretty reliable.

You also may have shed some light on the SureFire sudden death mystery. If those cells continued to rise in temperature even after testing on them ceased, the cells could conceivably trip the thermal shutdown protection system AFTER the flashlight has been turned off, which explains why we've had various reports of people using a flashlight just fine, turning it off and setting it on the mantle, only to find the following morning that the light wouldn't even turn on.

Tom, were you able to modify your testing equipment for low amp tests? You talked about going with 250mA.
