ALERO-
Check Battery junction.com they carry a "Tenergy" protected, rechargeable, RCR123A, 3.0 volt,900 mAh-$3.95 ea, and the REQUIRED Smart Charger for it-$12.95. While you're at check the deals on SureFires. There's no discount on the flashlight price, but they have a discount code "thankyou 2007" for 5%. Also, free shipping on conditional orders, no sales tax, and, virtually fistfulls of free CR123 Tenergy batteries with SF flashlight purchases!.....With my L2 I got 16 free batteries, 6PL-8, U2 Ultra-28, and the SF M6-40 free batteries! Now, even if you only pay $1 each for 123's that adds up to a pretty nice dicount on SF's! Almost all of them except rechargeable models get a deal. Their customer service is great too, I get immediate responses to my e-mail questions. I don't mean to sound like a salesman...just relating my experience FYI.
Good luck.
