I spent a good deal of time reading reviews of 'genuine' Nokia batteries. I don't subscribe to the view that if it's cheap then it's alright for the vendor to claim that it's genuine and/or new. I chose this seller because the reviews were encouraging and the price seemed reasonable.
I am pleased with this purchase. The battery arrived quickly. I think it's a genuine, new, Nokia battery. The hologram and printing on the battery are the same as my original. The contacts are gold plated and are not scratched by previous use. The battery is clean and unmarked. It charged quickly and has the capacity that I would expect from a new battery.
