Li-Ion Batteries - THE TRUTH

[Lorddrek]

Lorddrek: Thanks for taking a few minutes to do some tests. Exactly where were you seeing the 114ma though?

This was at the charger output where the battery is screwed into.

How'd you manage to measure that with the battery connected? Don't tell me you just connected the meter directly to the bare terminals with your meter set to measure mA's? Yikes!

All I'd need to measure this properly is a dead battery for the fitting. That, or 5 hands to hold the leads against those darn threads.

Thanks Magnus and asidrave for clearing up some of the misinformation that gets passed around about Li-Ion batteries.

I vote for stickiness as well!

Good info Magnus and adisrave - I work in an industry that deals with Li-Ion batteries as part of our primary product and all the information you posted is accurate. It also happens to apply directly to my e-cig experiences so far. I was always confused by the conflicting accounts I read here since they contradicted my own experiences and knowledge.

Not with the battery connected although with some battery mods that will be possible at some point. Yes to the bare terminal. Please explain "Yikes!" to me as I know of no other way to test amps with my meter.

I personally think the whole battery/charger thing is not very well covered and a very possible source of battery problems, early death, ect. There is not much solid info on this subject that an easy search can find and what is said is rather vague.

I've tried that. The Kill-A-Watt is not sensitive enough to even register the thing when it's definitely charging, so obviously it's not of much help when the green light comes on.

I thought that might be the case. Like you say, proper test equipment and a willingness to cut wires is the way to go.

[Lorddrek]

My discharged 200ma pilot battery charged for 3 hours before the green light came on. I will see if this lasts as long as it did before.

This could do with being in the sticky

Being 100% new to this whole e-cig thing, reading so much misinformation in print and in videos here regarding the charging of lithium ion batteries for these e-cigarettes is unsettling.

As this thread indicates already, it seems as if there are many users that have taken the battery treatment methods to older types and applied it to Lithium Ion batteries.

This thread should definitely be a sticky, it looks like you have many people pushing methods based on superstition rather then reality.

I wonder how much of the other stuff is also based on hunches vs fact.

Thanks for taking the time Magnus

Don't forget that Radio controlled planes use volitile Lithium Polymer batteries and not the Lithium-ion batteries that ecigs use.

A direct comparison may yeild inconsistent data.

Much as you wouldn't directly compare Nickle-metal Hydride(Ni-Mh) and Nickel-Cadmium(Ni-Cd). similar but not identical.
