I am pretty much a charging fanatic. I use a lot of lights, and charge a lot of batteries, daily.
All these years, I had been wanting a C9000 charger, but it just never happened.
I'm a huge 18650 battery fan, but also use RCR123 LiFePO4s, 14500, 16340, 17650, 26650, AA and D NiMhs, for other lights; so, I found myself in need of multiple chargers, to do the job quickly, since I'm also a stickler for always having charged EDC batteries, and regular maintaining all of my rechargeable batteries, regardless of chemistry.
Around Mid-2012, I started to find myself falling down the rabbit hole in Flashlight Land, and over the next five years, I've ended up with these chargers (Mostly XTAR units), starting with a pair of the modest Nitecore i4 V2, which were replaced, by D4s, then replaced by SC4s).
I find myself using analyzing and conditioning features very rarely. For that, I use the Dragon, and it seems to have fit the bill, for now.
As of today, I've pretty much scratched the C9000 off of my list of wanted chargers (not that I'm actually in need of any more chargers, at this time lol).
I appreciate the comments you guys have made. Thanks for sharing!
