Blue and white flashing light evertime I put batteries in

Every single time I go to replace the batteries. I make sure two are fully charged and insert them it blinks blue and white and i have to reconnect. However it's not easy. It takes hours of leaving both batteries out. Putting them in and out then even if unplugged for 5 min trying I have to charge them again which takes another hour to get them fully charged again. Usually after 5/6 of trying and leaving the batteries out for hours it will finally connect again. Sometimes it will recognize the second battery and other times it won't. It's extremely frustrating. Does anyone have a trick to fix this. I am considering a different type of camera. I just expected to pop a new battery in when needed, not have to go through this every time.
