Well then I will buy more batteries when they go bad. I like having the opiton to charge some cells fast in a hurry if you need them quick.
The steam is probably due the the cell venting poisonous gases. You are not suppose to charge the a single (1S) cell with anything other than 1S. You are risking your house being burnt down.
Here are some horror stories mainly due to wrong charging voltage and current: http://www.rcgroups.com/forums/showthread.php?t=719116
I usually charge at 1C but 2C is probably the max charging current that I would use on my rechargeable flashlight batteries without having a smoke detector and a fire extinguisher next to it.
Bewarned!

Lithium polymer? That is some scary stuff.
Protected single cells on a quality charger only for me.
Here is mine, one charger does all !
Charger
Power supply
I have a box with just about every lead and adaptor you can think of for charging or discharging just about any thing, the only thing that limit,s you with hobby chargers, is your imagination as you can make any lead or adaptor to charge any type of battery and places like hobby king sell leads dirt cheap that normaly just need a quick mod to suit your plugs.
I like to balance charge 6 x 18650,s
A link on hobby chargers it has some pic,s of a bit of some of the leads i use most oftern starting at post number 47

The links save me posting a few pictures
I think it's funny he has one of those burn your house down halogen lamps too ...
that lamp is saying .."Hey look that wasn't MY FAULT ..I didn't do it "
Seems like a very appropriate picture for a ..show us your charging set -up thread .
Well I'm pretty sure the CPSC would have put a recall on the battery chargers by now if they proved to be unsafe. And I also doubt that Energizer would make a product that they themself would be liable for millions upon millions of dollars of product liability. I know of no product recall on this charger.
A 15-minute charger isn't unsafe - it is pretty hard to make an NiMH explode. And my one is the pickiest about which cells it'll accept of any charger I've used.
It's just that charging at those rates (7.5A - actually quite a bit more, but pulsed to average at 7.5A) dramatically shortens the cell life. You'll be lucky to get 150 cycles out of the cells before they become useless. About ten cycles and the cells will be in noticeably worse condition and self-discharge becomes ridiculous.
My only use for the thing nowadays is to check cell quality - if that charger will accept the cell then it is definitely in good condition.
I don't think Energizer do sell them any more. I seem to recall they stopped supplying them several years ago.
There is some quite informative discussion in the Other Place on those:
My memory is at fault - they aren't as quickly destructive of cells as I remembered.
Thanks Don. Looks like that charger will serve my purpose well. And I can use sparingly if I want and still have some good cycle life from my cells.
And as far as that picture above in reference to using this charger is just that...an exaggerated scare tactic claim that is falsifying the safety about using this charger.
And technically the picture should be removed in reference to why it was originally posted to try and show false safety concerns with using the Energizer 15 min charger when there are none. Technically Energizer could sue for false accusations about their product if they really thought that it would prove damaging to this product in a wrong about way.
And that is just a little warning to the guy that posted it. Maybe he should heed his own warning.
And I checked the Energizer website. And they still have the 15min charger listed.
Click the link below and select 15 min charger option and then click the go button and it will take you there.
I broke it D:
I had that exact same halogen lamp in my living room and it burst into flames at 3am while I was sitting on the couch watching TV. The bulb popped and a 2 foot flame licked out the top of the lamp, had I not been home or even worse been sleeping my house would have burned down. That type of lamp is far more dangerous than a properly set up attended charging setup. The moral here is please don't charge your batteries unless you have time to babysit them and don't buy that halogen lamp either. I got mine on sale for 10 bucks and almost lost everything because of it.
I'll jump in here. Photo from a few months back. More lights, RC stuff, and battery packs these days. Solar charge controller upper right into four 6V 225ah deep cycles (in the coolers vented outside). That Skycharger 6200 clamps onto the lower pure sine inverter. This system also runs the TV, lamps, and the laptop upstairs.
I'm lost...wait...how do you connect multiple leads to the batteries again?? Forgive me, I'm a noob...
Did you assemble the solar system yourself? Do you have any good links on that subject?
