Mini preppers store batteries. You need them for your
flashlights, radios, lanterns, etc. You should also store batteries
for your smoke detectors and remote controls.
Write down all the batteries that you need for your emergency equipment, and
make sure that you have a good supply of them.
The most common batteries lanterns and flashlights are C and D batteries.
Small flashlights, headlamps and remote controls use AA and AAA batteries.
Fire alarms usually use AA batteries. Some remotes use extra small
batteries. Keep a list of the batteries you need, and watch for
coupons and sales.
One place to buy batteries at a good price is Costco. You can buy more
of them for less, and they will have a longer stale date.
Store them in a cool and dry place.
Most batteries have a shelf life of about 5 years, so you do
need to rotate them. Most people change their batteries for their smoke
alarms when the time changes or at the beginning of the year. Pick a date,
and check them at least once a year.
Do not leave batteries in your radios, lanterns, or other
emergency equipment that you are not using on a regular basis. The
chemicals in batteries will leak out after a few years. They will
corrode and ruin your devises.
