Can the Ultrafire charger charge RCR123s?

[KDOG3]

I have a couple of batterystation 3.7v 900mah RCR123s and I'm wondering if the Ultrafire charger will safely charge them with a spacer that I have. I have the little DSD charger that I got with them, but it would be nice to just have the one charger.

I do it all the time. But be careful with the Ultrafire charger and unprotected cells, if you leave them too long after the light goes green it will charge them to 4.4 volts!

And will this charger charge them independently - i.e. two cells of different discharge levels?

Yeah, good point. Thats' why I only use protected cells.

Yes.

Awesome. Thanks for the info. I know what I'm getting from DX next...

I don't think this is true of all Ultrafire chargers, mine only charges to about 4.13Volts, I always check my battery voltages after they come off the charger.

Just to be clear, the one I have that can overcharge them is a Ultrafire WF-139

Mine is the same model.

I have both the WF-139 and WF-138 - both only charge to no more than 4.17v. I have even left unprotected 18650 for a few hours on the green LED, and still no over charge.
