I bought this battery, because my old battery has slowly but surely given up the ghost. The delivery went smoothly. So purely with the new battery in my Nokia and ... invite nil. The display in the mobile display shows me not supported charger. The old battery with the new compared, both are identical. So the old battery back to the phone, and lo and behold, it loads as it should. New battery back in, same problem. Have the new battery will be loaded into an external multi-charger. Worked perfectly. Conclusion: The loading of the new battery in another charger works perfectly, but is very tedious because after removing the battery from the phone, all settings (date, time) need to be readjusted.
