Should an 18650 take 12 hours to charge?

I have a hamster that runs around the wheel really, really fast.

Beware - should the wheel be inadequately lubricated it could seize up, resulting in the injury or death of the hamster. As an ocelot the best course of action would be to eat it and discretely provide a replacement.

I have been researching for an answer to my question and came across the following article which gives an explanation:

Batteries Explained and Safety

If anyone is interested there is a well formatted version of this document here. Pretty good reference IMO, but there are a couple of mistakes in it. For example ICR batteries don't have a typical max discharge rate of 23 C. Probably meant 2-3 C.

And you trust a guy who states "Do the math and you come up with an average "best guess.""??
I trust the ones who know how and do the actual tests: Flashlight information
But then again, I was working with high performance flashlights about 6 years before I discovered vaping.

There are many good sites out there. Yes the "best guess" was in quotes. Most of us end user do not have the equipment to fully test a batteries at all levels needed. Most of what we do is "best guess". For example.. feel your batteries during charging if they get too hot then don't use them. Okay now answer what is too hot? Do we all have thermals to test the heat dissipation as they are being charged to look for variations?

Grats on flashlights I guess.... doesn't really float my boat but whatever. Considered they use power differently than we do as does the RC cars guys. I just happen to read different forums and then form an educated guess by gathering all that information together. But please feel free to post all the scientific data with batteries that I am sure every vaper would understand.

Well if you would have taken the time to actually look at the site you would have found the sections on battery testing and charger testing. What you fail to understand is the people who really know batteries learned from high performance flashlights years before mods hit the market. And unlike you making an "educated guess", we've dug up the data and tested it, we speak not just from what we've read, but from what we've learned from actually doing.

I believe the Charger is at fault the more I read. It's a Trustfire TR-001. The batteries are Blue and say IMR 18650 2800mah. I ordered AW IMR 18650 batteries yesterday. Granted, these read 4.1 V on the iTaste after a full 15 hour charge, and they last through chain vaping for at least 12 hours. But the charge time is excessive. Time of a new charger!

The answer is absolute not it should not take that long. No batteries should come that dead in the first place. Get a Nitecore Intelligent charger and AW, MNKE ,Panasonic batteries and get rid of Trustfire ones. You want the best you can get as others have said batteries are key.
