New Nokia Battery frm NOKIA

Few weeks back, received a DHL delivery. Whats that? I tot i got some surprise from someone but as usual NOPE! Its a new battery from Nokia to replace my old mobile battery. Why? I also not sure wats goin on with da old one, but they say i can change mine, and since its free and New, why not?

And need to thanks Edmund's mother, Auntie Christine who told me about this.
Big envelope! But oni a small piece of battery inside the big DHL bag.
