Lithium ion batteries are also affordable to manufacture.

The downside: Lithium ion batteries incorporate an electrolyte (lithium salt) dissolved inside a extremely flammable solvent. when the batteries short-circuit, they could overhead--causing failure, and occasionally generating them erupt in flames.

What About Other Batteries?
Sony, the maker with the computer batteries that Dell lately recalled, also would make batteries for Apple, Hewlett-Packard, Lenovo, along with other companies. Other than Apple, none of those firms have lately recalled any Sony batteries, as of the writing.

Battery recalls haven't been restricted to laptops. In 2005, lithium ion batteries inside a Nikon electronic camera, a Belkin GPS navigation system, plus a Polaroid convenient digital video disc participant have been recalled, according towards customer item security Commission.
