[HELP] GE Digicam J1470S DRAINING BATTERY EVEN SWITCH OFF

Leaving my fully-charged Li-ion battery mounted in my GE Digicam J1470S turned off for 2 days, emptied my battery?

Is this normal? With your digicam, do you have problems like this?
It's brand new and I already send it to the store where i bought it, they already change the battery but still the same... Their tech guy says it normal which is opposite in my side. I need your opinion and how ABOUT your camera too?... thanks in advance..
