The Sony laptop battery recall has hit 100,000, tripling in size since yesterday’s announcement that 35,000 were being recalled due to overheating problems. The recall now includes Li-ion batteries used in some Lenovo and Acer laptops as well as the original list of Dells, HPs and Toshibas. All of the recalled models were sold between 2004 and 2005, with two-thirds being sold outside of the US. Sony also noted that the faulty batteries were made by the same factory that produced a batch of recalled batteries two years ago.
