I want to try some rechargable batteries in my Surefire G2, it has a Malkoff bulb rated between 3.8-9 volts. Can I use 2) 3.7 volt RCR123 batteries or stick to the 3 volt ones? I also have a new Malkoff MD2 that can take a rechargeable 18560 but there rated at 3.7 volts, will they work?
That one. I use it for my L2, comes with 2 battery sticks and also the charger, that's the black box, it itself just plugs into the wall. Ive been very happy with the performance on the set-up. Cant beat the price
I have a G2 but have not run the RCR's. RCR's normally come off hotter (you said 3.7V) than 3V, but you said you had a range up to 9V, so you are still under the 9V and should be Ok. I just recently put an after market Cree R2 LED ($19.99) rated at about 230 lumen's in my G2. Works great, and gives longer run times for my 2XCR123. Here is the link. Look down to the Cree up-grade.
