Your charger does that because it is momentarily trying to drive a constant current through an open circuit (when you remove the batts), which causes the voltage to spike. Don't forget, the charger is actually running off 12v input and is using an internal switching power supply to boost that 12v to whatever it needs to charge the attached pack.
