When I received this seller mr! Trade, the reference battery is BP105R but the charger is noted BP210E. I did not know how to use the battery in the charger, and I felt an obvious inconsistency. I wrote to the seller located in Wehrheim (Germany). He replied in 24H assuring me that the two products were well tolerated despite appearances, with orders for installation. And indeed, I have reached a firm clip to position the battery in the charger BP210E. And it works well now, and the loading time seems right. I did not test loading with the car adapter. 4 stars because nothing seemed obvious to the implementation and use.
