CHARGING [email protected] VOLTS

[9X25]

Howdy folks.

DISCLAIMER:
This is in no way a recomendation to anyone; don't try this at home, kids.


In the past I was charging the Li-Ion cells at 4.25 volts and watching the current.

Now, I charge at 4.5 volts and I notice current eventually goes to zero.

I've probably shortened the life of the cellc(cycle life), but since I have an unlimited free supply of all types(NIMH,NICD,LI-ION), why not have some fun!


2 17500 light up an overdriven 5 watter just as nicely as 3 123 cells and last longer(runtime), IMO.

Ok, flame away.....

Hello 9X25,

I believe your disclaimer covers it all.

I did that with some of my cells and they died after 6 cycles. They had excellent run times during those cycles, but now they are dead.

Good luck with yours.

I killed many of 14500 and 93447 about two years ago by charging constant current of 400mA.

Well, since noone else has asked, I guess I will. How is it that you have an endless and free supply of batteries? /ubbthreads/images/graemlins/thinking.gif Are they surplus packs or something?

If you have any extra 17670s I'd be interested in buying some. /ubbthreads/images/graemlins/wink2.gif

Hello,

Thanks for asking LitFuse :-)

I charge mine with a specially designed charger that
limits the voltage to 4.220 volts and limits the
max current to 1 amp (18650 graphite cells).

Take care,
Al

Mr. AL, Litfuse wasn't asking you. And you didn't even answer his question, D'OH!


Litfuse: send me a PM if you're really interested.

Hmmmm, that's very interesting 9X25...

So i guess i DIDN'T answer a question he WASNT asking me...
What does that tell you?
Is it just possible that people DONT answer questions
that they ARENT asked? hee hee

This is one for the record books :-)

Take care,
Al

Mr Al,

sorry, it sounded like you had tried to answer a question that was asked of me. My apologies to you for sounding rude.
