The OP is in Malaysia. Battery quality is a common problem in many places. At least that is what my daughter told me after she returned from extended visits to India and Thailand. She found that it was not unusual to buy what appeared to be a sealed pack of new batteries only to find the whole lot to be bad.
As for Pentax quality and the possibility that the camera is dead. Sadly, the general quality of new dSLR cameras is not up to the historic standards of what we have come to expect from the photo industry. According to Consumer Reports, a significant number of Canon (5%), Nikon (5%), Olympus (4%), and Sony (3%) dSLRs require replacement or warranty service. (They lacked sufficient data for Pentax, but indicated that the brand is no worse than its competition.) That is one in 20 cameras going out the door going back in as defective. Not good.
As such, it is important for new camera buyers to be aware of dealer return policy and camera warranty details before purchasing. The new buyer should also take care to thoroughly exercise their new toy to find any bugs or issues that might be present while the camera is still under warranty.
