I have an Inforce 9VX light for work that I'm partial to.
It runs on three CR123 batteries and burns through them quickly.
I would like to move to rechargeable. It has been a while since I screwed around with rechargeable CR123 cells. When I last did, they were dodgy at best.
I'm assuming the tech is better now. I was looking at Nitecore NL166 rechargeables. I have two Nitecore lights (I know they are Chinese and not generally liked) that I have had excellent luck with.
Is buying six of these things the most economical decision for a rechargeable solution?
I determined that 17500 cells are essentially 1.5 times the size of a CR123.
Does that mean two (2) 17500 rechargeables would work as an alternative?
Lastly, I noticed Battery Junction (are they still the best place to buy this stuff?) has three (3) variations of 17500 including:
a) Ultrafire 1300 mAh 3.7v "protected" LI
b) Saft LM-17500 A Size 3000mAh 3V Lithium Manganese Dioxide (Li-Mn0.2) Button Top
c) Saft LS-17500 A Size 3600mAh 3.6V Lithium Thionyl Chloride (LiSOCI2) Button Top
I apologize for the newb questions but I notice different voltages and chemistry here and don't want to waste money or return shipping!
Thanks for the space.
