The Finnish giant, which produces nearly a third of all mobile phones sold worldwide, has been plagued in recent years by exploding handsets, due to low-quality replacement batteries made to look like Nokia's own products.

"With this new Nokia authentication program, we are directly attacking the counterfeiters who manufacture potentially unsafe batteries," Razvan Olosu, a senior official with the group, said in a statement announcing the move.

"The hologram label enables consumers to identify that the battery they are using is indeed an original Nokia battery."

The label will be a sticker with a holographic Nokia logo on it -- a three-dimensional image produced by a laser beam on a metallic surface -- making forgeries difficult.

According to Nokia, more than 40 of its phones have exploded worldwide due to faulty batteries, but in all of the cases the power packs were counterfeit.
