Using six or so inches of 12 or 14 solid copper wire, and a
PR-2 flash light bulb, this device can be used.

By bending the wire a bit, you can test any cells from
AAAA to D. After testing a few cells, you can get a
rough idea if the battery is useful, by how bright the bulb
glows.

Voltage available doesn't necessarily mean the battery is
useful. I found this out years ago, with carbon zinc cells
that read 1.5 volts, but which do not power a device.

True, no load voltage is unreliable, BUT using your method, you will have to
keep in mind a *reference briteness* for each sized battery!! Which might
not be so bad for that limited range of sizes.....

A radio-shack-type tester varies the load for each type battery, essentially
"normalizing" the meter, so's you don't have to make any power translations.
And also, the radio shack type testers take a very wide range of batteries,
from button cells to 22 V jobbies.

For you greenies:
A battery that "fails" in one context may be quite adequate in another
context. For example, I can take a dying AA battery, put it in my wireless
moose, and it will run the mouse for sometimes months!!! So in light-duty
applications, you can really milk the last erg of energy from some cells.

AAAA battery?? Must be the diameter of a pencil lead....

Tech America, a now extinct division of Tandy/Radio Shack, used to
give out a little clamp-on style tester that was very similar and also
did a load test. Free with any purchase sometimes, just bring in the
coupon and pretend to look around at others. Got a couple of them.

This is what it looks like if anyone ever comes across one.

Contacts on the side for 9V.

I have that but prefer:

They also used to give away a pretty nice stainless steel pocket
knife. The edges were safe to give to small children as toys but if
you spend a career getting them sharp, they are very nice. Got
several of those too.

I got both of them. Use the old Rat Shack one more often though.

One bleeding-heart type asked me in a recent interview if I did not
agree that "violence begets violence." I told him that it is my
earnest endeavor to see that it does. I would like very much to ensure
- and in some cases I have - that any man who offers violence to his
fellow citizen begets a whole lot more in return than he can enjoy.
