How to do the tests with basic kit?
Insert one test battery and screw the bulb until it turns
on. Record the time and battery size and model. Inspect the bulb
every 15 minutes until it completely turns off. Then record the
time again and calculate how many hours and how many minutes
did your battery last.
The bulb that you receive with your kit has a magnifier that
helps you to see the filament.
Even at the last moments of your battery life, the filament may
still be red. So wait until it loses all its light and redness.
If for some hours you are not able to inspect the light, turn
it off. Turn it back on when you are ready to inspect it again
every 15 minutes. Keep track of the hours that you turned the
light off and deduct it from final hours that you calculate.
to turn off the light, you may loosen the bulb by turning it
counter clock wise or by removing the battery.
The battery holder that you receive with your kit is designed
for the D size battery. To test other sizes, that are smaller,
you will need to put something in battery holder to raise its
bottom and since other batteries are shorter, you will need to
use a piece of metal such as a spring or screw as a filler to
attach the battery ends to the connectors of battery holder.
How to do the tests
with standard kit?
- Fill the battery holders with 4
different brand batteries.
- Screw the light bulbs in lamp
holders so that they all lit.
- Make observations every 15 minutes
and record the time each battery looses its power.
- At any time you are not able to
continue your observations, loosen all light bulbs so they will turn
off and stop consuming electricity.
