What are the longest lasting, highest mah rated rechargeable CR123 batteries I can get? They're for a fenix P3D
That torch takes 2x cr123.
I've got the PD30 which takes the same batteries. I find that I can just about squeeze in a 17670 3.7V Li-ion rechargeable from Deal Extreme.

The CR123a cells are 3V each right, totaling 6v for two in series? whereas the 17670 is just 3.7v. So your LED emitter is running at nearly half voltage? Whats the light output like?
Goan, the only rechargable cr123a cells I've seen were 600mAh, which do not last all that long unfortunately. There are some on ebay for a reasonable cost but you'll be changing them often if run in turbo mode 🙁

There's a switching regulator inside which in theory should mean it makes no difference, provided you stay within the voltage range it can cope with.
I've just tried a very unscientific test, switching between a pair of CR123's and a 17670 and they seem about the same to my uncalibrated eyes.
If I was buying a new battery for this torch though, I'd get the 16mm diameter ones (possibly sku.3273 ?) to make it easier to get them in and out.
And if I was buying a torch again, I'd make sure it took the higher-capacity 18mm diameter batteries.
I've got a P3d that I don't use a lot as the cr123a cells are so bleeding pricey so an alternative would be great. I use an L2d but the light from the p3d is better.
If youre finding that the output with a 17670 is about the same as two cr123a cells then I'll give it a try. Is the 17670 cell a really tight fit with some fettling required or is it just a bit tight?
It doesn't just drop out. I can only get the 17670 cell in and out by unscrewing both ends and then gently pushing it in/out.
However, if [url= http://www.candlepowerforums.com/vb/showthread.php?t=180963 ]this thread[/url] is to be believed, they won't work very well in the P3D - I guess the forward voltage must be too high.
Instead you might have better luck with a pair of 3.7V Li-ion batteries, such as [url= http://www.dealextreme.com/details.dx/sku.19627 ]these[/url]. The energy density seems to be about the same as my single cell, though still not as high as the non-rechargeables (about 6.4Wh vs 7.8Wh).
Get your ruler out before ordering though.
But while you're ordering from Deal Extreme, you could also just buy one of their newer torches.
CR132a non rechargeable (unfortunately) from www.component-shop.co.uk/ are 99p each, and seem to be lastingf just as well as the £3-odd panasonic ones i have been using.
My batteries last for ages, but then as Goan knows i'm a stingy light theiving barsteward who'd rather ride ninja than climb a fireroad with lights on.
I have a TK11 that runs on 2xCR123's.
I've just ordered a pair of trustfire 18650 batteries and a charger from dealextreme for about £9.61. I'm supposed to get an additional 40% run time over the paired cr123's.
Makes sense when you account for the space lost due to terminal button and one end of the casings of each of the cr123s.
Gotta be worth a try for less than a tenner.
These should do the trick!

I bought some of these
came within a week or so.
Seem to work ok, can't guarantee they are 1000 maH, but last 2 hrs on next to highest setting on a P3D
As martinb above, I got some 1000maH ones from some eBay seller in the States. A pair would run for about 2 hours in a BLT Ozone 21e light as opposed to about 1.5 hours from the 900maH cells I had before.
