Overdriving LED-based lights with rechargeables can shorten the LED's life, in some cases, so I generally do not recommend this. However, a few folks have tried AW's MP700 cells and batteryspace.com's Powerizer RCR123a cells. The A2's a great light; kkwarth's recommendation of the Executive Defender is also great. And those are for the wife. Reserve a Kroma MILSPEC for you; it will light up just about anything and fit in your pocket.
Here is the A2 Rechargeable thread.
The A2's incandescent light throw was impressive. I want an LED based torch that can match or exceed that one.
