Apple Demonstrates Energy-Efficient MacBook Battery at MacWorld

Steve Jobs’ absence hasn’t prevented exciting things from happening at this week’s MacWorld Expo in San Francisco. This morning, Apple unveiled the new 17 inch MacBook Pro, complete with a new energy efficient lithium-polymer battery.

According to the company, the MacBook’s battery can run for eight hours on a single charge and retains 80 percent of its capacity for up to 3,000 charge cycles. That’s a big upgrade from the 13 and 15 inch models, which only have 300 recharges.

Apple’s battery retains its long life with the use of an embedded chip that keeps track of charge level, temperature, and manages the charging current.

Speculation abounds as to who will be the battery supplier, but Apple hasn’t provided any leads. Possibilities include Toshiba, Sanyo, Panasonic, Mobius Power, Actacell, and Boston Power.
