The Patona I got for my 4 year old granddaughter toys. The wear of normal baby cells was very high and I decided to bring rechargeable batteries. So that no more bottleneck I ordered 2x4 Stück.Eine good decision. The power-2200MA 1.2V, depending on the use of toys 6-7 days. The batteries can be charged and quick charge Normal charge. Very noteworthy is the depository of the battery cells. The batteries are kept in a transparent PVC box. The box can be closed by a lid.
