When charger is a universal charger. That means you can pinch one wider than batteries with the stroke of the pen and you can the two electrodes (+ and -) to move individually over several centimeters so that it is in principle no matter, at which point the battery has to be charged his contacts. With me that charging worked well, if you ("loads" fully charged "") the lamp may believe. That's it then but also already. Neither batteries was recognized by the Lumia 630. Due to the adventurous construction of the charger I shall take care not to allow a working (original) battery charge, because there is no protection against reverse polarity or short circuits and neither the electrodes on the charger nor the (usually 3!) Contacts on the battery are clear marked "or" Earth "- as a" + "." Conclusion: Not even a functioning charger is used, not to mention the completely incompatible batteries.
