NiCad

Nickel Cadmium (NiCad) is the most popular and durable type of rechargeable battery. They are quick to charge, last approximately 700 charge and discharge cycles, and work well in extreme temperature conditions. Unfortunately, NiCad batteries suffer from "memory effect" if they are not completely discharged each cycle. The memory effect reduces the overall capacity and run time of the battery.

NiMH

Nickel Metal Hydride (NiMH) batteries do not suffer from the memory effect as the NiCad counterpart. Compared to a NiCad battery of equal size, NiMH batteries run for 30% longer on each charge cycle. They are also made from non toxic metals so they are environmentally friendly. They downside of NiMH technology is the overall battery life. These batteries generally last for 400 charge and discharge cycles.

LiON

Lithium Ion (LiON) is the latest development in portable battery technology. These batteries do not suffer from the memory effect. Compared to a NiMH of equal size, a LiON will deliver twice the run time from each charge. Unfortunately, these batteries are only available for a limited number of models and are more expensive than NiMH. Similar to NiMH technology, LiON batteries have a life expectancy of 400 charge and discharge cycles.

Smart Batteries

Most new notebooks use "smart" batteries with internal microprocessors. These special circuits communicate valuable charge/discharge information with your notebook. This helps run useful features like the battery fuel gauge while providing extra safety.

Poly Switch

A "poly switch" provides self-resetting protection in case you accidentally short circuit your battery.

Prevention of Overcharging

As the battery cells begin to heat during charge, a thermister in your battery pack changes resistance telling the computer to stop charging the battery further.

Multiple Cells

A battery pack consists of multiple high-capacity battery cells inside. These high-quality NiCad, NiMH, and LiON cells are used to guarantee maximum capacity and service life.

Fuse Protection of the Notebook

A current and temperature fuse provided inside the battery pack to insure that your battery does not damage your notebook in case other devices fail during periods of severe overcharge or short circuit.

Self-Resetting Breakers

Self-resetting thermal breakers prevent severe overcharge in case your computer doesn't sense that your battery is fully charged. This device also protects the battery from damage in the event of short circuit.
