Be aware - I spoke with SUREFIRE and their CR 123 batteries (I pay 6.50 for a set) are rated at 1400 Mili-amps. Good batteries for lights that need these cells.
I use FENIX lights myself, but a local cutlery shop carries these batteries which are better and cheaper (by 1/2 the price) than others.
P.S.(SIDE NOTE) This shop that I bought from sells Surefire lights as well, which have similar specs as my Fenix lights but for like 4 to 5 times the price as Fenix. (Scratching head here) - I WANTED to buy a surefire, but the price and fact that Surefire's specs are similar made me wonder ....why spend more? Can anyone shed some light.....pardon the pun.
