The short answer is to ditch the batteries. They're not designed for cold weather. The longer answer is a three-step process: First, and most important, check with your camera's manufacturer to make sure the body will continue functioning in the cold if it has a good source of power. You may have to write and ask this specifically, because the published ...
According to the guys at Magic Lantern, when you open the SD card door and the light flashes while it accesses the SD card, you should wait until several seconds after the light stops flashing as it is still accessing the card (which is silly, because that light has one job!) or you can cause the camera to lock up and drain the battery.
I've just got my camera back from repair and this was apparently caused by water damage to the DC-DC board, an expensive repair but I hope that my camera will now work well for some time to come! I've not yet worked out how the water got in - but I'm suspecting a damp camera bag after a seaside shoot.
The Bower XC-CE6 3-in-1 Individual Battery Charger for Canon LP-E6 description at amazon.com says it can charge your LP-E6 batteries via USB. I've never used one.
I had to take mine to a Canon service center as none of the methods suggested online (switch off, remove battery/lens, insert battery/lens, switch on) made the error code go away. I got the repair covered by manufacturer's warranty. Apparently Error 80 is a somewhat typical error code for this camera model.
I don't know if it's exactly the same thing, but earlier in October, Canon released a product advisory for their LP-E6 batteries and the LC-E6 charger. Full details can be found here.
Unfortunately, the fact that batteries perform poorly at low temperatures is a fundamental characteristic of most battery chemistries. As such, the only real solution is to either keep the battery warm, or switch to an exotic battery chemistry (and exotic batteries are not easy to get a hold of). The best idea I can think of is to fashion an external ...
The problem may be the voltage rather than the mAH. A standard AA is 1.5 volts. If your battery is only providing 1.2 volts, it may be insufficient voltage for the circuitry to operate on.
How long have you left them on the charger? From completely dead, it can take quite a while to charge the batteries. I would leave the batteries on the charger for 8+ hours and then try them in the camera by itself, without the grip. If they don't work and other batteries do work in the camera, then it sounds like a dead battery. Another option you could ...
Without actually testing, I am reluctant to say with absolute certainty, but I won't let that stop me -- I will just make a list of assumptions :-) Assuming stacked exposures of the same total time as the single bulb exposure, that your are not using dark frame noise reduction, that sensor power efficiency does not get significantly worse as it heats up and ...
In general, there are two problems with low temperatures: The battery capacity is severely reduced; the lower the temperature the less usable capacity. Lubricant or bearings used for the moving parts of the camera may stiffen, so it takes more power to move the shutter and mirror, possibly more than the battery can deliver. Lubricants in cold weather: ...
When I'm out in the cold, I bring several batteries. One's in the camera (of course), and the rest are somewhere warm (inside my coat; near my body). I swap the batteries fairly frequently - probably on the order of once every hour or two, and I've been perfectly happy with the results. I'm using a Canon 40D, and I've used this technique at temperatures ...
