Sony has finally given in and started to recall its own batteries, but so far just in Japan and China. The company has announced it's recalling 90,000 of its Vaio notebook batteries, 60,000 from Japan and 30,000 from China.

Sony has issued the recall for its “customers' peace of mind”, not because they have caused problems yet. The battery flaw that has led to around 8 million of them being recalled worldwide is that little pieces of metal have been left in some cells during the manufacturing process.

The company has not decided yet which laptops in other countries have batteries that should be added to the replacement list.

The news means that Sony is considering a revision to its annual earnings outlook. It's been hit hard by the costly recall, as well as a PS3 price cut before the console has even been released. More financial troubles may be in the pipeline if Toshiba goes ahead with a suit against the company claiming damages for loss of brand reputation because of the recall.

Sony predicted operating profits of about $1.1 billion (£591 million), which is 43% less year-on-year. However, analysts at Morgan Stanley have told Reuters they estimate an operating profit of around $455 million (£245 million), but that the following year should see a recovery at $3.15 billion (£1.7 billion).
