Bad RCR123's

[redham]

I bought 4 AW RCR123's and a Lumens Factory D26-LED Special 3.6 volt 250 Lumens Lamp from lighthound when I got my 6p 2 years ago. Funny thing is that none of the RCR123s have ever worked (properly), I didn't bother to return them since I thought I would be able to use the RCR123s for other electronics that use 123s. The lamp would turn on and then cut off 2 mintues later.

Now I have in my collection, 6p, fenix ta21, fenix tk11, and 2 new e2dl (newer version)

None of the rcr123's work with any of these lights. I recently pulled them out of the draw again becuase the e2dl's are supposed to be able to take rcr123's. Is there anyway I can test them?

I hear the newer e2dl's might not take the 17670's so my options will be limited to primaries and possibly rcr123's. I want to figure out if its definetly a bad batch of rcr123's or the lights that I have.

Ok , but not sure how they are bad ?

Do you own a Multi Meter ? , what charger are U using ? are they charging up to 4.2v ?

You may need to be a little more specific and detailed .

Using a Ultrafire 3.7 rapid fire charger. I guess a better questions is why they won't work with any of my lights.

Are these protected RCR123's? If so, it sounds like the current drain for that bulb is too high, and the protection circuit on the cells (one or both) trips, to keep the cell from being damaged.

You will want to buy a Multi Meter .

If you dont have one , you just wont know whats going on .

Got a multimeter now..

Settings are DCV - 20V

Sample readings trial and error.

AW18650 Protected = 4.12
AW17670 Protected = 3.92

ICR123 Protected = 0.00

Pissing me off as, day 1 these never worked right. Did I screw them up some way? I always inserted them properly while testing them. They have been sitting in the draw for about a year now.

0-volts = protection circuit tripped ...

Take that 18650 , + to + and - to - from a good cell to the tripped cell , to open the circuit .. You may need to make contact a few times , and only hold for a second or two .
