bought some VERY el-cheapo CR123s

[325addict]

Just for testing purposes, I recently bought 10 very cheap "Golston" CR123s.

Tomorrow or so, I will be doing some capacity tests with 450mA discharge current. Let's see if they can live up to the expectations... they are 1400mAh, manufacturer rated of course

I am looking forward to your tests. You can also get Titanium Innovations branded CR123A's for $1 each and they test really well, nearly as good as Duracell, Surefire and 4Sevens brand CR123A's.

I've seen several tests of these Golston cells. None of them were very favorable. Here's one. Granted that's an old one, but I doubt things have changed much. It will be interesting to see how they do.

Although I use very few primary lithiums, I prefer to stay with the known good brands, as the cost really isn't that much more, considering......

@ TranceAddict: you couldn't say it more clearly!

I don't plan to USE these, especially NOT in series! I am just curious how they perform...

Oh, I thought you were going to stuff 6 of those bad boys in your SF M6 when you get it...

any results>?

It does seem like a good deal.....cant wait to see how the results of the cells come too.

 

[325addict]

have some results:

conditions:
A: discharge to 2.00V
B: discharge rate: 450mA

#1: total capacity: 919mAh
#2: total capacity: 872mAh

until about 75% of the discharge, voltage remains fairly constant at about 2.45 to 2.55V.

Don't gonna use them in an M6 though

Large currents don't seem to be the best thing to throw at these batteries.
Maybe I can use them in a P1D - on low and medium.

Cell temperature didn't rise at all, even not at the end of the discharge. Maybe this was because I cut them off at 2.00V.

Conclusion: you get what you pay for. I could only advise them for SINGLE CELL lights, that don't draw more than about 500mA!

that seems like nice size.

anything over 800mah i think is worth keeping in cr123's

Damn right.
