General Packet Radio Service (GPRS) is a radio technology for GSM (Global System for mobile Communication) networks which increases functionality offering the possibility of charge by amount of data sent rather than connect time. It allows for continuous connection to the Internet for mobile phone and computer users.

GPRS is very popular with small and large businesses around the world due so called ‘always online’ technology meaning users can access their e-mails whenever and wherever they want. Devices which make use of GPRS technology include mobile phones, Laptop computers, PDA’s.

As with all portable devices it is a requirement that the operational time when running from a battery pack is as long as possible. With such handheld devices becoming more complex and even more powerful, the power demands from such devices are also increasing; meaning battery manufacturers are constantly being pressed to develop battery technology to get the best out of new technologies.

The development of Lithium technology has meant that batteries have been developed that not only can cope with the high current demands of such devices, but it has also meant that such batteries can be made to be small enough to enable portable devices to remain portable i.e. fit in your pocket.
