NiMH or alkaline? When to choose rechargeable batteries over
disposable ones?
Should you always opt for rechargeable batteries? Is it cheaper to
reuse one battery instead of buying multiple batteries? Or are
disposable batteries better? When NiMH and alkaline come into play,
the answer will always depend on your specific needs. Read on to
find out when you like which.
It all begins with the flow of energy
The primary purpose of disposable and rechargeable batteries is the
same: to store chemical energy and convert it into electricity when
needed. When the battery discharges, a chemical reaction causes
energy to flow through an external path between the battery's two
electrodes. As the stored energy reaches its limit, the chemical
reaction slows down. In the case of disposable alkaline batteries,
this means it's time to recycle the battery.
What about rechargeable batteries? Due to the different chemical
composition of NiMH batteries, the "depleted" flow of electrons can
be reversed. By connecting the battery to a charger, electrical
energy can be converted into chemical energy. When the maximum
capacity is reached, the cycle is complete and the battery is ready
to release new energy.
Are rechargeable batteries cheap?
But considering that rechargeable batteries last between five and
10 years, you can save a lot of money over time, in most cases.
This can have a huge impact on demanding, power-hungry equipment.
After all, a single rechargeable battery can be the equivalent of
hundreds of disposable batteries.
However, for low-power devices with longer battery life,
rechargeable batteries are not always the best choice. Sticking
with disposable batteries might make sense if you consider the
average life of rechargeable batteries. Wall clocks can last for
months on a single charge, so an investment in rechargeable
batteries may not be as beneficial.
Understand your requirements
When weighing NiMH versus alkalinity, remember to understand the
requirements of your device. Does it need to last for months? In
this case, disposable batteries can usually be used. If you need
fast, robust and reliable power or frequent charging, rechargeable
batteries will be more economical -- and better for the
environment.
