Should an 18650 take 12 hours to charge?

please re read my post, you obviously misunderstood my point.

taken from your link:


even their normal charging is 0.5C..
but you missed the part of my post when i stated, charging above 1C can degrade the battery causing shorter life span, and possibly failure...

I'm not an expert... but please stop posting about things you have yet to fully comprehend... you got a long way to go.

Besides, believing those numbers on the link you provided, is like believing the MPG ratings at a car dealership...

Absolutely. Info that I am posting is tested already. I stand behind it. Just read your posts one more time. Rule of thumb. There is NO rule of thumb when using Li-ion batteries.
I've never seen so many wrong informations from veterans. You guys better get it together bcse people are believing in your posts. Somebody will get hurt.

Good intention YES, wrong info YES :(

If I asked you to tell me what is difference btwn ICR, NCR, INR and IMR what would you say? Yes, you can use internet to research .
Let pple say their opinion. Unfortunately this is not CPF... People who know will understand.If there are pple from CPF here....

Again :toast:

I would be very interested to know the different charging methods for the various chemistries and why some should not be charged at currents based on their C rating. Do some of these chemistries work in a way that charge/discharge currents are not a derivative of capacity?

Don't be that guy who makes fairly odd/generalized claims and demands to be believed just based on CPF membership. Share the info so we can see whether it floats or not.

Strontium... i really dont understand what point you are proving, but this is ECF not CPF.

a good number of users here can barely grasp ohms law.
One user actually used copper wire for a coil... but that's a different story
Do you think the average vaper really cares about proper charging cycles?
The better informed usually have to simplify things to keep the average Joe safe... Someone may mis-interpret good information and end up harming themselves.

so yes the 1C charge IS a rule, that most use within the RC world... because it is a compromise between charging speed and safety(idiot proofing).
yes there are batteries that can take a higher charge rate.
And No i dont trust what is written on a web site, or who someone i dont know claims as actual fact.
I have the equipment to do my own testing. :p

People will interpret what they read in which ever way they want.
saying "its okay to charge @ 2Amps when using good batteries", is never a good idea on this public forum.
Unless you know 100% that the audience reading it, fully understands why.

I'm not saying you are wrong or questioning your statements,
I'm just saying dont give someone the excuse to blow themselves up.

That's a scary claim on many levels. Try charging a "good" 10450 300mah at 2A, IMR or not. Charge and discharge capabilities are derivatives of capacity. Thus, batteries should ideally be charged based on C rating, not at a one-size-fits-all amperage.

I would have no objection charging any of my vaping batteries at up to 1C. I simply don't do that because I don't care to rig up my hobby charger every time I need a charge. So, I charge at the rates given by my simpler charger. Which is well below 1C.

Get good batteries and a decent charger and charging is just a matter of plugging a battery into a charger. It's not multi-cell LiPos we're dealing with here.

@Not aimed at BuzzKilla even tho you're the quoted one ;)

Obviously the difference is in the battery chemistry. I'd be interested in seeing a brief breakdown of the chemistries and their intended application differences if you could do so.

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

Good job Baditude. Everybody should read this.

Batteries Explained and Safety - » The Original Electronic Cigarette Social Media Network




Especially people who believe in 1C charging rule of thumb ;)

English is my third language, but I see that members do not have problem understanding my writing.

Last letter in ICR, IMR, NCR... means Round cell.
