stacking batteries in a charger

[madstabber]

How bad of an idea is it to stack 2 18350 batteries in a charger that is too long to fit them single. My charger will fit 18650 and longer but won't fit 18350's. So if I put 2 18350's in my charger stacked it will fit, but will it charge? and is it really unsafe or just kinda? Has anyone tried this and lived to tell about it? If so let me know how it went.

Please don't do that.....

 

[madstabber]

So it won't work?

that doesnt sound safe..

Please don't make a decision until you get a lot more replies.
Wait for the battery experts to come in here and give their opinion.

And definitely look at post count when weighing the replies you get.
Post count doesn't mean everything, but it does tend to weed out the background noise.


As for me, I have nothing to say, because I am not an expert in this area by any means.
But I do look forward to what comes of this discussion.

And that's all I've got to say about that.

That will not work. For many reasons.

For one, battery voltage needs to be lower than the charger voltage. Stacking batteries will double the voltage, and current would tend to flow to the lower potential, or the charger.

Two, a charger can't monitor each battery individually, if two batteries are in series.

There are more reasons. Just don't do it.

that made me jump when it finally blew LOL

If you want to charge batteries together at normal voltage, they need to be in parallel which you can't do with the type of charger you're talking about. You could put a "blank" (just a chunk of conductive metal) in the charger with your batt to fill in the gap

Please use the battery charger in the manner, which it was intended to be used.

We don't need to read about your charger experiment in the evening News.

Thanks for the responses people. I was just curious if it would work or not. I was guessing that it wouldn't but wanted to hear what you all thought. Live and learn.
