Anyone with a laptop more than a year old, knows that the battery in most units can barely run Microsoft Excel and a web browser for than 40 mins without demanding a charge – so it might come as a surprise to find out that most old laptop batteries could soon be powering communities in the developing world.
Computer hardware giants IBM have this week released a study that says old lithium-ion batteries such as those found in laptop computers could have enough life in them to power homes in rural slums.
The study found that 70% of laptop batteries tested were capable of keeping an LED light array on in a home for as much as 4 hours per day for an entire year.
