Nowadays we have become again witnesses of new recalling Sony battery packs for laptops in amount of 100,000 pieces. This recall is referred to 2.15Ah lithium-ion cell batteries which had been sold for HP, Dell and Toshiba devices.
The notice made by U.S. Consumer Product Safety Commission that states they have received 40 reports of battery overheating. The recall covers also Inspiron and Dell Latitude units sold about three years ago. It was quite a surprise for Sony as they did not sell the batteries directly, they were sold by PC makers, electronic stores and online retail dealers.
The reason of overheating is flaws in the PC and separate batteries sold outside the United States. And Sony report a number of incidents have occurred because of smoke and flames, some minute damage, flaws in the electrodes metal foils and small burns. There is an opinion that due to some adjustments in Sony’s manufacturing line, taking place in 2004-2005, from which the quality of cells in certain products suffered. Sony also say that only a small part of laptop battery packs were recalled which were sold within last six years. And it is almost nothing compared with 10 million Sony batteries sold to several major computer manufacturers in 2006-2007.
The request of U.S. Consumer Product Safety Commission for the manufacturers is to remove and replace the damaged batteries.
