GB/T18287-2000 is a standard, the product number is V5-364560 but I haven't found this battery anywhere.
The fact that the battery is using wires rules out the PP being directly compatible with Nokia battery, yet this is an advantage as when the original battery dies it should be easy to "recycle" the wires and connect them to any standard, unwired cellular battery delivering 3.7V. Theses are very common and the dimensions should not be a problem either.
One should also be able to upgrade the battery this way, it's possible to find 1200mAh or 1400mAH batteries with the same dimensions.
