The nasty, old school way was to lick them batteries and if it tingled your tongue, it was good.
Wiser and way more accurate way would be to find a tiny light bulb, same as the ones used in flash lights, then have 2 pieces of wires (18-24 gauge) and all you need is like 5"-6" for the wires. Touch one wire from the bottom of the battery to the side of the bulb and the other wire from the top of the battery to the bottom of the bulb.

Disclaimer: I am always right 50% of the time.
When I was trying to find out if a bulb was good or bad, I took a bulb out of a AA flashlight and into the other flashlight and the new bulb blew out. Those flashlight bulbs are designed for different sized batteries.
ex: see the attatched photo. Those bulbs are for AA and if used on larger batteries will blow.
I am trying to avoid buying a device only to find the 10 batteries to all be bad.
I've got 5 flashlights AA or D so don't need another one.

If you could lick both ends of a C battery at the same time, well, that would be impressive.
That trick only works with a 9 volt battery. 1.5V isn't enough to tingle one's tongue.

If you have nothing that uses C cells, and aren't going to buy anything that does, why do you care if the batteries are good? Hang on to them, and test them when the need arises. It doesn't matter if they're good now, only if they're good when you need them.

Yeah, it has to be a bulb that would obviously handle the voltage the C batteries dish out but a bulb from a flash light that uses C batteries should work but I guess you don't have that to begin with. Doesn't Duracell has some of their batteries come with a battery checker within the package.
I only saw them for AA and AAA batteries but I am thinking it should work for C batteries if it fits.

Oh yeah, you are right, duh!
If I found a chick who could do that, I would marry her on the spot!
I suppose he could use a paper clip from the other end to his tongue?
I was travelling and took the AA and the C flashlight with me.
The bulb on the AA needed to be replaced. I tried auto parts places like Autozone. No flashlight bulbs.
I ended up at Walmart. The choices were.
$1.00 for a AA flashlight that came with batteries and a bulb.
Or pay $2.00 for the pack of 2 new bulbs.
I went with the pack of two, in case one went bad.
I'll try one last search for the C flashlight. It is not in the vehicle and not lost or stolen.
I've got a flashlight that uses D batteries.
The bulbs in that one, might show if the C batteries are good, using the 5"-6" wire method.
Well this is an interesting fact:
AAA, AA, C and D batteries all are 1.5 volts.
How does that determine how many of each battery a device needs?
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?

2 C batteries. The bulb will be slightly (probably imperceptible) dimmer because of the slightly higher internal resistance of the C batteries.
