We seem to take batteries for granted these days and barely
give them a second thought. This popular electrical device powers a multitude
of technologies from laptops to cars and phones to cameras. Since the invention
of the first battery in 1798 by Alessandro Volta, batteries have become a
common power source for many household and industrial applications- so much so
that the worldwide battery industry generates approximately $48 billion in
sales each year.

Batteries work due to a chemical reaction inside them that
causes electrons to flow from the negative to the positive terminal of the
battery.when all of the chemicals inside the battery have reacted, the battery
is spent. This is true for disposable batteries still in their original
packaging as well with each losting 8-20% of their original change every year
simply due to being stored in warm temperatures of 20-30 degrees Cecilius. The
same goes for rechargeable batteries, which lose a percentage of their change
each day when left off the charger and, despite the capability to be changed
repeatedly, will eventually die.
The battery is one of mankind’s top inventions because it is
due to the advances in battery technologies that people no longer have to carry
large brick phones and can now operate their smartphones for over 12-14 hours
on a single change.
