Bought this charger with the Placard states CHP4WB4 but when I opened the package with the charger it had stamped on the charger CHPRIUS. On reviews I get negative responces like: CANNOT CHARGE BATTERIES. or BATTERIES WILL NOT CHARGE. Should I take it back to dealer and related to dealer these reviews I am reading. Did Engergizer switch the charger and put in the Placard with CHP4W-B4 with the model CHPRIUS.
