A product advisory has been released for the Nokia-branded BL-5C battery manufactured by Matsushita Battery Industrial Co. Ltd. of Japan between December 2005 and November 2006.

It appears that in very rare cases, the affected batteries could potentially experience over-heating while charging. This is caused by a short circuit, which could make the battery dislodge. Nokia is still investigating the situation with the “relevant local authorities.”

While world-wide battery recalls are practically a dozen a dime nowadays, 46 million batteries still represent a staggering amount. Of course, most people will probably just miss the advisory or don’t bother. So, it remains to be seen whether a full 46 million little parcels of BL-5C will end up being whisked around the globe.

What few people are aware of is that lithium ion batteries are considered quite volatile relative to the other types of battery technologies available. Hence, the appropriate cut-offs must be built into batteries and devices, which drives up the cost. These safeguards are generally more than adequate to the task — until a manufacturing defect gets overlooked.

It is unclear who will ultimately bear the cost of replacing the batteries.
