Nokia, hit by a recent spate of reports, from Vietnam to the Netherlands, of its batteries overheating and catching fire or exploding, says a follow-up test by a Belgian consumer watchdog had shown its own-made batteries were safe for use, Reuters reports.Nokia said in a statement a new test by Test-Aankoop, conducted on November 17, showed all Nokia-made batteries were protected against short-circuiting, believed to be the cause of the problems. The Belgian firm said in a separate statement its previous test released earlier this month had accidentally included counterfeit batteries in the sample. But it said Nokia should address the issue of many forged batteries sold under Nokia’s brand.
