Batteries in electronic devices have been dangerous for years. However, the Sony batteries used to power Dell laptops were not only dangerous, but they were also deadly. Dell used these dangerous batteries to power more than 4 million of their popular laptop computers. These lithium-ion batteries were made by Sony, but their products were faulty and overheated.

Analysts jumped at the chance to crunch the numbers. Once the recall was issued, they estimated that Sony and Dell had to fork out about $400 million to get the dangerous products out of the market.

There were some very deadly scenarios including when Thomas Forqueran’s Dell laptop caught fire and ignited a box of ammunition in his car. That exploded his gas tank.

The next product is something most cooks have in their kitchens.
