I have two original Nokia BL-5J batteries and interesting is that one is 1320mAh and another is 1430 mAh. I think that last Nokia that used BL-5J was Asha 202 with 1320 mAh. And second last was Nokia Lumia 520 with 1430 mAh. And there is still available 1430 mAh in Amazon: https://www.amazon.com/Replacement-N.../dp/B00EZG3OGW
