Choosing the right battery for portable computing

Laptops are known to be tough hosts on their batteries. The host demands a stream of uninterrupted power but offers a poor working environment in return. As a result, the battery cannot provide the promised runtime and the service cuts short, often with little notice. In this paper we address the unhappy marriage between the host and battery, and examine what causes a battery to deteriorate faster than in other portable devices.

What's the best battery for laptops?

Batteries for laptops have a unique challenge - they must be small and lightweight. In fact, the laptop battery should be invisible to the user and deliver enough power to endure a five-hour flight from Toronto to Vancouver. In reality, a typical laptop battery provides only about 90 minutes of service. Many users complain of much shorter runtimes.

Computer manufacturers are hesitant to add a larger battery because of increased size and weight. A recent survey indicated that, given the option of larger size and more weight for longer runtimes, most users would settle for what is being offered today. For better or worse, we have learned to accept the short runtime of a laptop.

The energy density of modern batteries improves by about 10% per year. However, the benefit of better battery performance is eaten up by higher power requirements of laptops. This results in the same runtime but more powerful laptops.
