The camera is 7 years old and things happen. If you have the original Manual, look up the code error to see what it relates to. If you say you installed Fully Charged new batteries, then an event relating to C:04:00:00 could be a circuit board malfunction or the metal conduction ends that touch the battery are corroded. With a light look inside the battery chamber to see if any material is covering the contacts. If dirty, scrape and clean the surface.
If you don't use the battery for a long period of time even a new battery may become dead. You can try a new battery. If it still doesn't work then the problem is with the charging IC. u can also try a desktop charger instead of direct charger.
Sometimes the batteries will build up a memory if they are only used for short periods of time and never used to the point of going completely dead, so possibly getting a new battery online. B&H photo is a pretty good site. I know some chargers have an output to the cameras battery connector that powers the camera, and if that is plugged into the charger it will not charge the battery simultaneously. If the camera is working when plugged into the power source it usually turns out to be a battery problem. Sadly the only choice it to buy a new battery.
Yes, when both lights are on.. it means the battery is charging. The "charging" light should turn off once the battery is fully charged. If the "charging" light remains on 12 or more hours later, your battery might need to be replaced.
I got hold of Canon support. I had the same problem. Got a new battery, fully charged and would not run the unit. Canon told me to do a system reset. pull out main battery and aux battery (bottom of unit) and to power switch to aux for 90 seconds. the put batteries back and it should work. Hope this helps.
This is usually caused by a failed component in the power circuit within the camera and can usually be repaired fairly inexpensively. However, it's not a user serviceable problem and will need to be repaired qualified service technician.

My old Panasonic Palmcorder IQ shows a red light in both switch positions-camera and VCR. Maybe yours has red for camera and green for VCR so you could tell them apart. I found that the Panasonic battery that came with the camera was the cheapest kind with the least charging time. I bought other batteries, they were good for a while, but now, many years later, they won' t hold a charge. Since I am only recording inside of my house, I have resorted to using the AC wall socket for power. I have to take the battery out of the camera. I found a power plug-in hole (like ones on cell phones) in the battery compartment. I also found one of these holes on my battery charger. My camera came with a double ended power plug. I plug one end into my camera and the other end into the battery charger. I plug the charger power cord into the wall outlet, and I have power to my older camera. Maybe you can find this double ended power cord at a store or on line.
Did you know that there are 2 kinds of batteries? Some have memories and others do not rely on a memory. The ones with memories have to be fully discharged or they will only charge a little, and keep charging less and less each time they are charged. The ones without the memory can be charged fully without being discharged fully. Check into battery information on line to get more information. Maybe you can get the non-memory kind.
