OLPC has learned from experience that finding electricity is the main problem in getting the XO laptops to kids in developing countries. Many areas lack electricity, making it hard to recharge laptops. The group has come up with a number of novel ways to recharge the laptop’s batteries.

McNierney recharged the XO-1.75 with a hand crank. It takes 1 hour and 47 minutes to fully recharge the battery by hand, he said.

The battery is made with lithium ferrous phosphate, which he said is safer the lithium ion. The OLPC batteries are designed to last for five years and slow-recharging is one way to extend the life of the battery, he said.
