Sytem Technology ByuckHae Korea has developed a portable smart battery pack that extends talk-time, or battery life, of mobile handsets by 800 percent. The MPB 4000 lithium-ion cell portable battery pack has power capacity of 4,600-mAh about fourfold the 1,000-1,300-mAh capacity of regular rechargeable battery of cell phones. The portable cellular phone battery charger Mobile Saver MPB 4000 is touted as the world's first smart cellular phone-use portable smart battery pack.

Equipped with an in-house developed integrated circuit (IC) microchip, MPB 4000 identifies its chemistry and tells the charger which charge algorithm to apply while protecting the battery from overcharging, under-discharging and short-circuiting. Will be on display at Consumer Electronics Show 2005 Jan. 6 in Las Vegas.
The smart battery pack is planned for release next year, with an estimated lifecycle of 5 years, will sell at $60 per pack, the company said.
