Have you tried RCR123s in your PD3Q5? I tried them in mine and they don't work, I think its because the voltage is too high (3.7v instead of 3.0v), maybe you can get 3.0v RCRs?
I'm also looking for some recommendations (or even reviews) for a good 2 x RCR123A Charger and Batteries.
I looked at the charger that Lighthound and 4sevens offer earlier today and it seems good, but it would be nice to hear what everyone here has found to be good in their own use or from gathered knowledge here on CPF.
Can't go wrong with AW RCR123's from Lighthound. Their considered some of the best here on CPF. I have 2 AW RCR123's myself and they work great. I charge them with the newer Ultrafire WF-139 charger and have no complaints.
