Power demand is increasing annually as more people use more computing devices and get hooked up online. That said, developing technologies that better handle power management and, at the same time, consider the delicate nature of our environment are becoming the norm. New battery and power supply technologies contribute their fair share to this expanding power consumption situation as computer systems--be they desktops, servers, server farms, clusters or mainframes--are running 24/7.

It has been noted in the news of recent days that the expanded use of desktop systems and servers is putting a strain on the power grid. Every company manufacturing computer battery and power supply technology is aware of these facts and research and development departments continue to work on better and more efficient ways to handle these essential issues.

Evolving Battery Technology

Today's desktop systems easily rival and exceed the mainframes of yesteryear, yet power management and battery technology continue to be refined. This allows for a combination of software, chip and battery technologies to co-mingle in this delicate dance. For example, a long life replacement PC/AT clock battery contains a diode and resistor which prevents charging and controls the voltage required by the clock and configuration memory.

Multiply this fact by the tens-of-millions of systems in use and one can begin to see the need for this type of focus and concern. Using the latest battery and power supply technologies contributes greatly to more efficient laptop, notebook, and desktop computers. It also greatly extends the life of these devices as they spend more time crunching the daily business data.
