The Nokia-branded batteries can experience overheating, caused by a short circuit during charging. In this "very rare case" the battery can dislodge, the company informed. Presently, about 100 incidents have been reported globally, with no serious injury known.

For its BL-5C battery, of which the company has shipped more than 300 million, Nokia has several suppliers. Only batteries produced by Matsushita are affected by the problem.
