What is a battery cycle?

Cycle life is measured by the amount of times a battery
may be charged and discharged. Every time a battery is
charged and discharged, it uses one cycle. Cycle life is
very important in battery applications such as laptop
batteries and Power Tools batteries(drill battery). A
Ni-Cd batteryhas a cycle life of 500-1000 ormore cycles.

Introduction of New Battery Technology

The huge battery recalls from a few years ago showed that a flaw in the battery could have serious consequences for computer makers and consumers. Several batteries short-circuited and caught fire likely to property damage on more than one occasion.
This new battery technology that has been introduced by Panasonic will not only offer longer run time for laptops, but promises to be safer too.Compared with the 2.9Ah of current cells,the new batteries use a standard cell form factor and pack in 3.1Ah per cell.
In addition to the longer run time, it also features an insulating metal oxide layer which prevents overheating in the event of a short circuit between the cathode and anode.
