The title is the question.
Where do you charge your li-ion batteries?

In the charger.
I tried leaving them in the same room with the charger, but they just didn't display any intiative in getting together on their own.

I charge mine in my basement.

ha, ha, Lets clarify the question, In what enviroment do you charge your batteries, for saftey reasons? Thanks for the humor.

WOW
Nice set up!
I use my kitchen counter. I wish I had a gararge or basement were other's don't find my property community properity!!!

Quick question: how dangerous is this? I mean if the charger is a DSD charger is it risky to just leave it over my wooden floor to charge ?
Thanks for the advice and feedback!

Interesting. Just when I thought I'd conquered my fear of having lithium cells in my home...
I've got a couple unprotected 14500s and an UltraFire charger. I charge them on my bathroom counter.
I'm now considering some kind of blast shielding.

Yeah, I forgot the smileys, I'm glad you understood, and it was too good to resist.
On a more serious note though, I'd be interested in seeing the reaction of mainstream consumers to the responses that are received here.
Conversely, I'd be just as curious to see how many mainstream consumer have experienced some of the episodes that have been shared on this site. Of all of the people that I know, I don't know a single person who has had a LIon battery explode or burn, from a flashlight, laptop, mp3 player, cell phone, or digital camera. Of course, it does have to be qualified that that I only know of one person who uses RCR123 batteries in a flashlight, other than myself, and everyone else that I know of, who uses a LIon battery in a flashlight is using a Strion.

I charge mine in my bedroom with a DSD. At times, I've charged them in the trunk of my car from a 12v pack.
I'm ALWAYS careful to make sure that I have the correct polarity when inserting the cells since there's no nipple on them and it's easy to make a mistake in a rush.
I also spend the extra bucks on protected cells. I'm tempted to try some unprotected both for the cost and the availability of 2600mah cells but I'm terrified of them.
Nice setup you have there. :lolsign:
Are you afraid of having something like THIS happen?

I just use an old cake pan. I do them where I am to keep an eye on them.

In a custom plastic holder which sits on the top edge of a computer monitor in our home office. The basement idea is pretty good. I might consider that if I had a basement. How flammable are those floor tiles?
The plastic holder is next to my DC power supply. I set the open voltage to 4.20 volts. Then I set the charge current depending on the mah rating of the cell. I have not had any cells get much above room temp.

The tiles are ceramic, so not flammable at all.

Near my wallet and keys by the front door, so I won't forget them on my way out the door.

I only use protected cell (from AW) and charge them on my desk at work. No risk to my kids in case the building is consumed in a huge fire ball. :naughty:

On top of a stainless steel burner cover on my stovetop. I use AW's DSD charger with protected 18650s only. I always charge just one cell at a time, and I carefully inspect the cell to make sure I observe proper polarity when placing it in the charger. I only charge cells when I am going to be nearby for the several hours it takes to complete charging (my computer is in the living room not too far from the kitchen, so this last requirement is easy).

Hi there,
An explosion is caused then a large amount of energy is released in a short
amount of time. The energy can come from anywhere or anything.
Batteries are a source of energy and can release this energy in a short
amount of time, therefore batteries can explode. Since it takes
very little time to conduct current, batteries can discharge in a short
amount of time, which affects the power of the explosion. How fast
they discharge therefore is a big factor in determining how big the explosion
is. For example, an 18650 Li-ion cell wont even get hot if you discharge it
into a 10 ohm resistor, simply because the energy is not being released fast
enough. On the other hand, an internal short can cause it to explode like
a one-sixteenth (1/16) stick of dynamite.
Probably the recent battery-caused fires were started because the
cells developed a short, but the short was of a high enough resistance to
prevent an explosion yet would still cause resistance heating enough to
burn nearby combustable materials.
Li-ion cells can develop an internal short during charging, although it must
be a very rare thing to have this occur, as long as it's charged correctly.
I charge my 18650 cells in a charger built with a blast shield. The case itself
closes so that the battery is entirely closed except for a slot about 1/4 inch
wide and about an inch long to release energy. The case is made of fairly
heavy aluminum and was given to me by another CPF member a long time ago.
The case was originally made for something else.
I think what would make a cool blast chamber would be an automobile tire
mounted on a rim with the Li-ion cell inside the tire where the air normally goes,
and have the valve stem removed. If the cell explodes, the rubber of the tire
absorbs the pressure wave and vents it slowly through the open valve.
Would also need some heat sensors to detect temperature rise.
Would be kinda big though.
