Despite attempts by Nokia to put fears to rest about its cell phone batteries exploding, Nokia is once again on the defensive after a consumer organization claimed three batteries could short circuit. 

The claim came from a press release issued by Belgian consumer organization Test-Aankoop, which reported three Nokia batteries -- the Nokia BML-3, BMC-3 and BLC-2 -- are not protected from short circuiting. Nokia says the charge is false and that all Nokia batteries adhere to "stringent safety and quality measures, including short circuit protection."

Batteries have been a topic as of late, following a smattering of reports of cell phones exploding, including one out of the Netherlands in which a battery used in a Nokia 7210 exploded. Nokia has remained steadfast in its belief that any batteries that have malfunctioned have been non-original Nokia batteries. The No. 1 handset maker even launched an internal investigation, which found that in all reported cases, a non-original Nokia battery was to blame. The investigation found that the problems were caused by an internal short circuit due to careless design, an uncontrolled production process or both, Nokia said.

The handset maker has said it will be even more vigilant in its enforcements efforts, including alerting its own distribution channels to the dangers of counterfeit products; requesting their assistance in identifying sources of such products; and prosecuting parties found to be distributing counterfeit products.
