More than meets the eye.
Laptop batteries are the most important battery in the field of
rechargeable batteries, but they are also the most complicated and
regulated of all rechargeable batteries. The process alone to
manufacture a laptop battery is long. How laptop batteries interact
with the computer to function properly is another lengthy process.
Manufacturers are also working constantly to improve laptop battery
technology.
The process used to created laptop batteries involves a system of tests
and re-tests to insure safety and reliability. Inside that plastic case
that is the finished product, there are a number of components besides
the battery that make it work. Inside the casing, there are safety
fuses, breakers, thermistors, and charge electronics which all aid in
the functionality of laptop batteries. The battery pack casing is
welded together in a specific process and is then sent on for final
inspection. During final inspection, tests are documented for form, fit
and function and once the battery passes the test, it is labeled with a
lot and date code.
All those extra components added to the battery pack are essential for
laptop battery functionality. The thermistor controls the resistance of
the battery and tells the computer to stop charging when the battery
heats up as it completes charging. The circuit breaker helps protect
against over charging and short circuits.
Laptop batteries are built with the best quality battery components
that can be found. Battery cells are ensured to yield the highest
capacity and safety qualifications, whether the battery cell is NiCD,
NiHM, or Li-Ion. Some batteries are even equipped with their own
microprocessor that communicates important charge information to the
computer.
Information about laptop batteries proves that they are some of the
most advanced rechargeable batteries available. Now when choosing a
laptop battery, you won’t just see a black box, but rather a
mini-computer that helps your laptop to run reliably and effectively.
