Old fashioned battery tester
Stormin Mormon
flash light bulb (PR-4 is good, the old screw in 112 is
better, more close to the proper voltage). Then, take about
six or seven inch long piece of #10 or #12 solid wire. Wrap
one end of the wire around the bulb. Curve the rest of the
wire, so it looks like a letter C, or G.
Touch one end of the battery to the lead spot, on the bulb.
Touch the other end of the wire to the other end of the
battery. If the bulb lights, the battery is OK. Works for
AAAA through D cells. Have to bend the wire a bit, for
different sizes.
After using this for a while, you can also roughly guess the
battery state. New, used, weak, dead. By how bright the
light is. If using a PR-4 bulb, you can also test 3 volt
lithium photo batteries.

No shit Sherlock. You are really telling me that if you put a bulb
across a battery and it lights that the battery is ok? That's amazing.
Your daddy was some guy!

fun, especially if the washroom had multiple bulbs ;)

Old fashioned light meter:-
Open your eyes, if you can see it is light. If you can't see it is dark.

Hardly scientific ... guess by how bright the light is?
A load test must also include a voltmeter and some knowledge to be a real
test.
But, your Dad certainly understood an important fact: A cell or battery
must be loaded to evaluate its condition.

Reminds me of the very first camera I ever bought (no idea what brand it
was). The 'exposure metering system' on it was an eyepiece you looked
through and saw a piece of film with the numbers 1 to 10 in rows (white on a
black background). As the numbers increased, they got darker until you
couldn't see the next one. That was the number to set the exposure ring on!
Not sure what branch of the sciences this was based on (witchcraft maybe?)
but it didn't work, I do remember that...

that's about only time and place I use it. Why would you say
less effective?

Many times you can get a good estimate without load.
A rechargable is best tested by
a very loooong test.

Just measuring the no-load voltage on these will give a fair
estimate.
