Dumb Question

LED Flashlights – General Info
1

Hi Folks, this is a simple (and dumb) question I know, but the people here have always had a lot of patience... so here goes. I have a 6-D Mag-Lite. I purchased some 2-AA to D cell converters so I can use my eneloops in the light. When fully charged, I get 1.45V off a single AA eneloop. When I combine two AA eneloops in the converter, I still get 1.45V. I assumed the voltage would be doubled.

So what is the point in doubling up the batteries if the output is the same as a single battery? Is it just longer run time?

If that's the case, can I use 6 converters (12-AA batteries) without damaging the torch?

Please forgive my ignorance.

in series parallel the voltage is same current doubled in parallel series double voltage same current

is what you said longer runtime, if was in parallel series giving 2xvoltage(out of standard D cell) you can fry the bulb/driver

better use battery with the same charge level

jaja so nap XD

Yes you can do that. The point of the converter is to use AA batteries instead of D batteries. So it's going to be in parallel therefore you only get 1.5v.

Thanks how2,

Does batteries facing the same way means "series" ? So I can use 12-AA batteries and it will still be only 9V's?

What is the benefit of doubling up the cells?

Thanks.

Thanks also to MixoMaxo

If you are getting 1.5v when in the converter then it's safe to use.

It's parallel facing the same way the benefit is that you will get double capacity.

Here look at this

Thanks Again how2, I told you it was a dumb question...LoL.

There are no dumb questions just dumb answers.

Novel concept.

It would seem so.

Well, that diagram made it real simple to understand. I'm a little smarter now...Thanks.

It’s just the opposite, Mixo.

Connecting in Parallel
When connecting in Parallel you are doubling the capacity (amp hours) of the battery while maintaining the voltage of one of the individual batteries. This would be used in applications such as laptop batteries, some scooters, some ups backups, etc. Use a jumper wire between the positives of both batteries and another jumper wire between the negatives of both batteries. Connect your positive and negative wires to the same battery to run to your application.

jaja really sry pod7381 to put confusion on your head, I confused series and parallel words on my mind, not concept :P

Ty johnny to correct my mystake and for the crystal explanation but I well know that, as you can guess from my precedent posts ..I have prooofs xD

about cr123/16340 batteries

or old posts... about a 12v Dx led


CrackHead your first post(or old user new account?) was just a childish insult to my person, take exemple from johnny pls
you are NOT welcome! xD
jokig have fun be happy :)

No dumb questions. If one does not know something ask.

If no one ever asked "dumb questions" we may have missed out on some of the worlds greatest breakthroughs and inventions.

Simple thoughts/questions lead to great solutions and answers that end up helping us as humans to make us all more enlightened, informed, and advanced.

This thread alone will help someone somewhere answer a question they have. We all know that doing something new with batteries can result in bad stuff if you have no clue what the outcome will be.

Good job to the OP for asking and all that have contributed info. :)

BLF...

Making the world a better place :)

wise words m8 :slight_smile:

Well said, I definitely learned something with the simple clear explanations. Thanks to all.

my old granny who is long gone used to say

if you don't know ask the question you may never know the answer

wise words that i have never forgot and gave me the inspiration to never be embarrassed to ask for a opinion from others that have more knowledge than me
