OK, thank you for clarifying that Venom. After rereading it a few times I had a feeling you were talking about two seperate incidents. :+1:
Ronin42 was exactly right about the leaking battery you found in the monitor.
As far as the “exploded one” …… beats me??? Glad it was in a drawer though to contain the shrapnel. 
The Xtar is not hard to run, but it is just a fast charger. IMO you will be much better off starting off with the Lii 500. As far as how long does the charge take. If you are charging a “close to empty” 3500 mah battery at 1000 ma (1A) it will take approximately 3.5 hours. 2500 mah / 2.5 hours, and so on. These are estimates of course, but they will give you some idea. :+1:
I usually get my Eneloops from Thomas Distributing / more from Thomas or sometimes Light Junction . Personally I don’t mess with Amazon or FleaBay and I know if I get them from either of the above they are the real deal.
I got one Lii 500 from Banggood & one from Gear Best.
In fact, GearBest has them on sale right now. HERE is the link to the sale.
I got the SV2 back on a “Black Friday Sale” from IMR Batteries .
Illumination Gear is good also. And HERE is another good place here in the USA also.
No you do not have to buy a USB Power supply with either of those two chargers. They come with a power supply. You are in the USA so make sure it says it has a US plug.
Yeah, you might need two if you buy a lot of batteries and use them a lot. But……. start with the Lii 500, learn about it and batteries n’ such. Then if you need another…… get it. :+1:
Here is some more good info on LiIon batteries, click on it. Lithium-ion battery safety 101
Oh yeah, I figured out why everything is “getting mushed together” in your posts. 
You are indenting several spaces when you start a new paragraph. IF you will stop doing that it will not “mush together”
See how what you wrote in the quote above…. I fixed it.
Sooooo, start the new paragraphs on the left edge of the page and your spaces between paragraphs will be there……
