How many C batteries would it take, to power a flashlight that uses 2 D batteries?

I don't want to start blowing bulbs.

I need to borrow a friends C device, test my C's and throw them out, if no good.
Every device I have, that works (from TV remotes, to flashlights, to cassette players) use AAA, AA, or D's.

That same website said a 9 volt battery is clearly 9 volts.
And the other flashlights or lanterns that use those rectangular batteries are 6 volts.

If you take them apart you will find that they contain 1.5 volt cells connected in series.

If you want to be technically correct, you will call your C batteries C cells.

You will eventually learn all of this in General Science class.

I had a flashlight that used C batteries.
I lost the darn thing.


Following you so far...

I have close to 10 C batteries and need to test them as good or bad.

Just how LONG was this "flashlight" that it needed ten C cells? (wink wink, nudge, nudge, knowwadimean??)

Any way to test them without a device?

Device? OK, so if you have nothing to use these batteries with, is there a purpose in testing them? I'm trying to envision this...

"Yep! I have TEN, count 'em, TEN working C-cell batteries. Just tested them. (sticks thumbs behind suspender straps, leans back in chair and smiles knowingly) I just have then sitting on a shelf so that I can admire them."

What types of devices still use C batteries?

Dunno. (wink wink, nudge, nudge, knowwadimean??)


Seriously, I can't imagine buying a product just to use some old C cells I had lying around, and I'm one of the cheapest people you'll ever meet. Give 'em to a kid. Donate them to a Radio Shack recovery group.

That was pretty much the main reason why I bought my second motorcycle (used of course). I was keeping spare gas in a 5 gallon gas tank and it was getting stale so I bought a new bike to make sure of that gas too. Couldn't let 5 gallons of gas go to waste! (wink wink, nudge, nudge, knowwadimean??)

Will someone loan you a device knowing that you might lose it?

I do not want to throw the batteries out if they are good.
And I did not say that while spitting venom like some which is an unfortunate characteristic of all websites with forums.

I think some of us are having a little fun at your expense. OTOH, as some have said, knowing the batteries work now doesn't mean much if you don't use them for x number of years.

It doesn't, the device determines the type and amount of batteries required. If you have a flashlight with a 3 volt bulb it would take two 1.5 volt batteries, a flashlight with a 4.5 volt bulb would take 3. A D cell flashlight would work just fine on AAA, AA, or C cells, it just wouldn't run as long.

I have a flashlight that uses two D batteries.
I have a flashlight that uses two AA batteries.
I have a cassette player that uses 3 AA batteries.
I have a cassette player that uses 4 C batteries. No, I can not test it with my C batteries because the buttons on the device do not work.

How many C batteries would it take, to power a flashlight that uses 2 D batteries?

It would take 2, as the voltage is the same, you would just get less usage from the device before the batteries died

Exactly, ...well not exactly on that first sentence, which was me just being silly. The silliness part of my post has smilies . The serious part started out with "Seriously" (I thought that was a dead giveaway, but apparently the dead don't want to be given away around here). The second sentence of your post reiterates the idea of moving on and not worrying about that stuff about to go moldy in the back of the refrigerator and trying to put it in something new and tasty.
