re: Primos Camera issues

I had the same camera with some issues about killing the batteries and they told me to reformat SD card and it seems to have fixed it. Not sure if it will help yours but maybe worth a try.
To reformat an SD card in your computer:

Insert SD card into computer (If a window opens, close it)
Left click on START
Left click on MY COMPUTER or COMPUTER (This will open all the icons in computer)
Locate in the REMOVABLE STORAGE section, the SD card DRIVE and RIGHT CLICK (This will open up a drop down box)
Middle ways down the box is the word FORMAT – LEFT CLICK FORMAT
Press START
Make sure that the File system is FAT 32 and uncheck the Quick Format Box if it is checked (We want a full format)
You will then get a Warning box that states all will be removed from card – CLICK OK
Once the card is formatted, you will receive a message on the screen that says FORMAT COMPLETE.
Insert the SD card into camera and test.
